FAQ

MIK Projekt is an engineering company specialized in design, manufacturing, supply, installation, commissioning, and maintenance of industrial boiler and thermal energy systems. We deliver complete EPC solutions from concept through long-term service.

MIK Projekt is headquartered in Belgrade, with a manufacturing facility in Noćaj (Sremska Mitrovica). We are active throughout Serbia and the region, with reference projects in around 10+ countries.

Our engineering lineage traces back to 1931, when Rapid — the first Croatian boiler manufacturing company — was founded in Zagreb. Through the merger into TPK Zagreb (1946) and the establishment of MIK Projekt as an independent entity in Belgrade in 1991, we have been continuously working on industrial thermal energy systems for more than nine decades.

Yes. MIK Projekt is a family-owned company led by Igor and Aleksandar Delikladić, sons of the founder Đorđe Delikladić. Continuity of people, knowledge, and accountability has been preserved across three generations of engineers.

We have documented 217 completed projects across 23 industrial sectors, with over 8,715 MW of thermal capacity and over 2,163 t/h of steam capacity delivered through our portfolio. In total, we have supplied more than 280 boilers to 144 unique clients across 71+ cities.

Our permanent team comprises around 20 engineers and technicians — design engineers, combustion engineers, site fitters, service technicians, and quality controllers. For larger projects we mobilize verified partner resources from a long-established collaborator network.

Our references cover 23 sectors — including district heating, thermal power, food & beverage, chemical, pharmaceutical, oil & gas/petrochemical, paper, textiles, wood/timber, sugar, brewing, dairy, defense, hospitals and public facilities, as well as specialized applications such as desalination.

References exist in around 10 countries. The majority of projects are in Serbia and the region (Bosnia and Herzegovina, Montenegro, North Macedonia, Croatia, Romania), with select references outside the region such as Libya (Khoms Power Station — desalination).

Contact us via the website contact form, by email at office@mikprojekt.com, or by phone at +381 11 306 51 06. For an initial estimate, send us a basic technical specification — duty (steam, hot water, thermal oil), capacity, pressure, available fuels, and basic site information.

Single point of accountability means that MIK Projekt has one team responsible for engineering, equipment procurement from OEM partners (burner, pumps, controls), mechanical and electrical installation, commissioning, and subsequent service. The client does not contract separately with each sub-supplier or coordinate between them — every interface and every responsibility sits with us.

We design and deliver: water-tube boilers (hot water, high-temperature hot water, steam, heat recovery, high-pressure), fire-tube boilers (hot water, high-temperature hot water, steam, heat recovery, specialty), thermal oil boilers and electric boilers.

Design range by boiler type: water-tube up to 500 MW, fire-tube up to 20 MW, thermal oil up to 12 MW, electric up to 30 MW. The largest single reference in the portfolio is a 140 MW hot water boiler at the "Zapad" district heating plant in Novi Sad. Below 0.5 MW we rarely engineer custom units, as off-the-shelf commercial equipment is usually more cost-effective.

Fire-tube (smoke-tube) boilers are simpler, less expensive, and suited to lower pressures and capacities up to roughly 20 MW. Water-tube boilers operate at higher pressures and capacities up to 500 MW, respond faster to load changes, and are better suited to demanding industrial processes and large district heating systems. Selection depends on pressure, capacity, load dynamics, and footprint.

Yes. Thermal oil boilers — using diathermic fluid as the heat carrier up to 350°C — are used when the process requires high temperatures at atmospheric pressure, typically in chemical, food, wood-processing, and oil industries. Thermal oil boilers are within our standard scope, up to 12 MW capacity.

Yes, every project starts from the client's specific requirements — fuel type and quality, capacity, load dynamics, available footprint, and regulatory environment. Engineering is not catalog selection but tailored design for your application.

The highest efficiency achieved in our systems is 98.2%, realized through a combination of condensing heat recovery, economizer integration, and combustion optimization. Typical values for modern water-tube and hot water boilers with economizer are 92–96%, while steam boilers without economizer typically run at 90–92%.

Yes. All our systems are supplied with a PLC/SCADA control system, with full integration of control panels we design and assemble in-house (including Lamtec, Siemens, and other OEM partner automation). The system supports remote monitoring, alarming, event logging, and remote diagnostics 24/7.

Yes, and it is one of the fastest ways to cut fuel consumption — typically 4–8% in steam systems. We design and manufacture in-house both primary economizers (bare-tube bundle integrated into the boiler) and secondary economizers (condensing, finned-tube, as a stand-alone unit). On a project at British American Tobacco Vranje we installed a 4.54 MW waste heat utilizer without interrupting production.

Yes. Industrial heat pumps make sense where there is a source of low-temperature waste heat (process cooling, wastewater, flue gas) that can be lifted to a useful temperature — typically 70–120 °C. They are often integrated in a hybrid setup with existing boilers covering peak demand, reducing annual fuel consumption by 20–40%.

Power-to-Heat are systems that use electricity (often from renewables or during periods of negative power prices) to produce heat — through electric boilers or resistance heaters integrated with existing thermal plants. The business case applies to operators with access to electricity markets, flexible heat demand profiles, and CO₂ reduction targets.

Yes. Geothermal energy covers a significant share of heat demand at industrial sites and district heating systems where geological conditions provide adequate temperature potential. Before design we assess geological conditions, available temperature, and hydraulic capacity, then select the technical solution — heat pumps, heat exchangers, or direct systems — often combined with boilers covering peak demand.

A modern industrial boiler typically operates for 20–30 years with regular maintenance, proper feedwater treatment, and quality interventions. Pressure parts (boiler shell) can last longer, while ancillary equipment (burners, controls, pumps) is typically upgraded every 10–15 years.

The assessment starts with the age and condition of the pressure parts (certification status, wall thickness), annual fuel consumption, emissions, and safety ratings. When pressure parts are sound, modernization (new burners, economizer, controls, insulation) typically delivers 60–80% of the benefit of a greenfield plant for 30–40% of the investment. Otherwise we recommend a new build.

Yes. Our digital remote monitoring platform tracks key operating parameters — temperature, pressure, fuel consumption, alarm status — in real time, 24/7. Early-warning detection flags anomalies before they cause failure, enabling proactive intervention for clients under maintenance contracts.

Yes, within the EPC scope. Feedwater treatment (softeners, RO, deaerators) is sized per EN 12953-10 and the boiler manufacturer's requirements. Treatment system delivery is executed through our partner firms KB Tehnika and Ovex, while we retain responsibility for integration and overall system performance.

We design and deliver systems for: natural gas, biogas, light and heavy fuel oil (LFO, HFO), LPG, biomass (woodchip, pellets, bark, briquettes, agricultural residues), coal (including pulverized and biomass co-firing), wood gas, waste heat, waste materials (waste-to-energy), electricity, hydrogen, and combinations (dual-fuel/multi-fuel systems).

Yes — this is one of our most common modernization projects. Conversion typically involves replacing the burner, adapting the fuel supply system, installing new controls, and re-certifying the unit. The existing pressure vessel is retained if it is in sound condition, which significantly reduces investment compared to a new boiler.

SAACKE low-NOx burners we deliver as standard operate with up to 25–30% hydrogen blended with natural gas without modification. For 100% hydrogen operation, we supply specialized burners from leading OEMs dedicated to this technology. "H₂-ready" provisioning is considered at the engineering stage if the client is planning a future fuel transition.

Yes, we have references on biomass installations. We support woodchip of varying moisture content, pellets, briquettes, bark, sunflower hulls, agricultural residues (e.g., corn cobs, sugar by-products), and biogas systems. The combustion system is sized to the fuel's calorific value, moisture, and ash content.

Yes. We have experience with coal-fired systems across various coal grades, including pulverized coal and coal-biomass co-firing systems for district heating and industrial steam in the region. We design for safe operation, reduced emissions, and fuel flexibility.

Waste-to-Energy (WtE) converts non-recyclable waste streams into useful thermal or electric energy through controlled combustion. We engineer industrial WtE systems where waste (production by-products, waste fuel) replaces fossil fuels. This requires careful sizing due to variable fuel composition, corrosion risk, and stricter emissions control.

Yes. We supply and commission gas engines for combined heat and power, with heat recovery from the engine cooling circuit and exhaust gases. CHP makes economic sense when there is steady year-round heat demand, with total fuel utilization typically exceeding 80%.

Timeline depends on scope. A modernization of an existing mid-capacity boiler house typically runs 4–8 months. A new large-capacity boiler house with full infrastructure runs 12–24 months. The main drivers are boiler manufacturing (10–30 weeks), burner and controls lead times, and regulatory permitting.

A typical process moves through six phases: technical consultation and site survey, conceptual and detailed engineering, equipment procurement and manufacturing, mechanical and electrical installation, cold and hot commissioning, and handover with performance acceptance testing. After handover, the warranty period and optional long-term maintenance contract take effect.

We deliver both. Most projects are EPC — one contract, one team responsible for everything. We also supply equipment only (boiler, burner, controls, pumps) when the client has their own contractor for installation and commissioning.

Every project has a named project manager and a lead process engineer. During installation and commissioning, mechanical fitters, electricians, and combustion engineers are deployed on site. Team size ranges from 4–6 for a burner retrofit to 15+ for a new large-capacity boiler house.

For an initial estimate we need: intended duty (steam, hot water, thermal oil), required capacity (MW or t/h), operating pressure and temperature, available fuels, and basic site information. A detailed quote requires a technical specification or a site survey.

Yes, we have experience with these situations. First step is a review of existing documentation and the as-found site condition, followed by an assessment of what is reusable, what needs rework, and what needs replacement, with a revised schedule and single point of accountability from the moment of takeover.

The client receives complete handover documentation: as-built engineering drawings (mechanical and electrical), material and equipment certificates, test reports (hydrostatic, performance acceptance, emissions), operation and maintenance manuals, operator training, and a defined contact protocol for the warranty period.

Yes. We coordinate with regulatory authorities, integrated/environmental permitting bodies, accredited emission measurement laboratories (per SRPS ISO/IEC 17025), and international classification societies (DNV, Lloyd's Register, Bureau Veritas, ABS) for marine and offshore projects.

We typically guarantee rated thermal capacity, combustion efficiency at nominal load, NOx and CO emission values per the applicable directive, and steam or hot water quality parameters. Values are verified through acceptance testing in the client's presence, per EN 12952/12953 and equivalent standards.

Standard warranty is 12–24 months depending on the manufacturer and component type. It covers manufacturing defects in materials and workmanship provided the equipment is installed, commissioned, and maintained per our instructions. Extended warranties are available under a long-term maintenance contract.

With SAACKE low-NOx burners on natural gas we reach NOx ≤ 30 mg/Nm³ at 3% O₂ — compliant with EU MCP/IED directive limits and national regulations. For LPG and heavy fuel oil we configure the burner with flue gas recirculation (FGR) and air-fuel optimization to meet applicable emission limits.

Acceptance testing is performed with accredited instrumentation during commissioning, with a written report covering efficiency, emissions, and operating parameters. The report serves as evidence of contractual compliance and supporting documentation for the client's environmental permits.

Yes. For installations legally required to use continuous emission monitoring (CEMS) per the applicable regulation, we integrate measurement systems for SO₂, NOx, CO, particulate matter, and oxygen. Systems are designed per SRPS CEN/TS 15675 and undergo regular verification testing.

We provide a technical baseline of the current installation, recommended emission reduction measures (burner replacement, FGR, economizers, condensate recovery), and the engineering documentation required for regulatory permits. Our systems are designed for compliance with applicable IED, MCP, and EED directive limits in the country of installation.

NERP (National Emission Reduction Plan) is Serbia's national framework requiring existing large combustion plants (≥ 50 MWth) to meet IED Annex V Part 1 emission limits by 1 January 2028. We support clients with technical assessment, intervention selection (burner replacement, SCR/SNCR, dust abatement), and tender documentation preparation.

Per the applicable Serbian regulation, large combustion plants are those with thermal input ≥ 50 MWth — subject to stricter emission limits and continuous monitoring obligations. Medium combustion plants (1 MWth to 50 MWth) fall under the MCP directive with somewhat lighter but still binding limits. The 50 MWth threshold also affects technology and equipment selection.

We provide engineering support in the form of feasibility and integration studies for carbon capture (CCS — Carbon Capture and Storage, CCU — Carbon Capture and Utilization) on existing or new thermal energy plants. Scope covers techno-economic analysis (post-combustion, pre-combustion, oxy-fuel), boiler/steam cycle efficiency impact, site integration, and the engineering basis for the EPC phase with specialized CCS providers.

Yes. The audit covers combustion efficiency measurements, loss analysis (radiation, flue gas, blowdown, condensate recovery), controls assessment, and identification of savings potential. The deliverable is a technical report with a prioritized list of interventions, investment estimate, and expected payback.

We perform CO₂ emissions calculation and reporting based on fuel consumption and emission factors, supporting EU ETS documentation, MRV (Monitoring, Reporting, Verification) processes, and client internal reporting. For installations with CEMS, we integrate continuous monitoring and reporting.

Main cost drivers are: boiler type and capacity, burner class (standard/low-NOx/ultra-low NOx), scope of auxiliary equipment (water treatment, condensate return, economizer, flue gas duct), site preparation and civil works, and controls scope. Indicatively, equipment is 50–65% of project cost, installation 20–30%, engineering 5–10%, with the balance going to permits and commissioning.

We work to a fixed lump-sum price once the technical specification and scope are finalized. Price changes during execution are only negotiated if the client requests scope changes/additions or if unforeseen site conditions are discovered. This is standard practice under an EPC contract.

We prepare the technical documentation required for funding applications — energy savings, emissions reduction, and payback projections. The application process is handled by specialized funding consultants. We have clients who have financed modernization through EBRD, KfW, and energy efficiency programs of the relevant ministries.

Yes. Serbia's Ministry of Environmental Protection periodically issues tenders co-financing boiler house procurement, replacement, reconstruction, and remediation projects — including conversion to lower-emission fuels (pellets, biomass, natural gas). We prepare the technical documentation and specifications required for these applications.

Typically 3–7 years, depending on fuel, existing losses, and project scope. Fastest payback usually comes from burner replacement with combustion air optimization (1–3 yr), condensate return (2–4 yr), and economizers (2–5 yr). A specific calculation is produced based on measured parameters of the existing system.

In our Noćaj manufacturing facility we produce thermal energy system components: gas trains (DN 50–DN 800), liquid fuel skids, finned tubes, primary and secondary economizers, air pre-heaters, heat exchangers, air and flue gas ducts, structural steel (EN 1090 EXC 3), and access platforms. Large-capacity boiler components are manufactured through our partner network.

Yes. Our Noćaj facility manufactures and supplies individual components and assemblies to other system integrators, boiler builders, and EPC contractors — with complete production documentation, material certificates (EN 10204 3.1/3.2), and welding certificates (EN ISO 3834-2, EN ISO 9606-1).

Production is certified to EN ISO 3834-2 (highest level of welding quality), EN 1090-2 EXC3 (structural steel with CE marking, audited by TÜV Austria), EN ISO 9606-1 (qualified welders for REL/TIG/MAG processes 111, 141, 135), and ISO 9001:2015 (TÜV Austria). Documentation is aligned with PED 2014/68/EU for pressure equipment.

Our engineering documentation aligns with ASME standards (including PTC 4 for performance testing), DIN EN, BS, AD/TRD, GB/T16507, IBR, JIS, GOST, and other international standards. Specific ASME Section I/IX stamps (for the US market) are not currently among our certifications — for projects requiring them we work through licensed partner manufacturers.

For all products from our facility we provide EN 10204 3.1 material certificates (3.2 on request), including seamless and welded steel pipes (EN 10216/10217) and structural steel (EN 10025). Documentation accompanies all pressure components, structural steel, and pressure equipment in line with PED and AD 2000 standards.

Detailed information on employee count, annual turnover, registration data, and financial indicators is provided on request for tender pre-qualification, under signed NDA where applicable.

Yes. MIK Projekt holds an SME (Small and Medium Enterprise) certificate per the EU SME definition. The certificate is available for download on our "Documentation" page and can be submitted with tender applications and ESCO/EBRD/EU financing where SME status is required.

We maintain an occupational health and safety management system per ISO 45001:2018 and the SCC** standard (Safety Certificate Contractors — a mandatory requirement for contractors on European industrial and energy sites). We record and report on work injuries, near-misses, and safety incidents (TRIR, LTIFR indicators). Indicators are provided with tender submissions requiring HSE pre-qualification.

We hold general liability, professional indemnity (E&O), and Contractor's All Risks / Erection All Risks (CAR/EAR) policies. Coverage levels depend on the specific project and are tailored to contract requirements. Policy details are provided on request.

Yes. Our Code of Conduct covers ethical business standards, anti-corruption, environmental protection, human rights, diversity, and supplier relations. The document is available in Serbian and English versions for download on our "Documentation" page.

Yes. Our team of approximately 20 permanent engineers and technicians, with a verified network of partner manufacturing and installation capacity, enables simultaneous execution of 3–5 medium-sized projects or 2–3 large-scale projects. Capacity and schedule are planned in the pre-contract phase.

Yes. For serious prospects we arrange site visits to reference installations, subject to prior notice and host client approval. This is standard practice for projects above a certain size and we recommend it — particularly if you are looking for evidence of operation on the same fuel or technology.

Yes. We service industrial boilers, burners, and ancillary equipment regardless of manufacturer or original installer. The first step is a diagnostic assessment, after which we propose a maintenance plan or intervention scope.

We currently maintain over 500 industrial burners, 500 fans, and 55 boiler houses in Serbia and the region. This installed base is a source of data on typical failures, equipment behavior under real conditions, and optimization opportunities.

For clients under a regular maintenance contract, the guaranteed response time is 24 hours. For emergency interventions outside a maintenance contract, the response time is 48 hours. Our emergency response team is available 24/7.

We offer annual preventive maintenance contracts, with guaranteed response times, scheduled inspections, and priority access to spare parts. Service scope is tailored to client needs and equipment type.

The minimum period for a regular maintenance contract is 12 months, allowing for seasonal inspection planning and continuous system monitoring.

Yes, we maintain our own spare parts warehouse and an established supplier network for original OEM parts — including older and rare equipment models. Clients under maintenance contracts have priority access to inventory.

The training program is tailored to the installation and covers: theory (operating principles, safety procedures, regulatory requirements), practical training on the plant (start-up, normal operation, alarm response), and written documentation (operating manual, service log). Training can be part of project handover or a stand-alone service on request.

Yes. Our teams are familiar with domestic and European regulations applicable to boiler systems. We help you maintain compliance with statutory requirements — from technical inspections and certifications to reporting to competent authorities. We maintain complete technical work records ready for inspections and audits.

Modernization covers boiler life extension (structural inspection, targeted repairs, component renewal), burner upgrades for NOx compliance, replacement of outdated components (controls, heat exchangers, discontinued parts), and structured commissioning verifying all parameters against design documentation.

The main advantage is "single point of accountability" — the complete EPC cycle under one responsibility, from design through long-term maintenance. The client does not coordinate between multiple contractors, there are no interface risks, and there is one warranty and one team supporting the system throughout its operational life.

Three main differentiators: (1) more than nine decades of continuous engineering experience with a family-company identity, (2) one of the strongest certification portfolios in the region (ISO 9001/14001/45001/50001, EN 1090 EXC3, EN ISO 3834-2, SCC**), (3) an integrated model covering design, in-house component manufacturing, an OEM partner network, and long-term maintenance.

SAACKE (industrial and marine burners, combustion systems), Wilo and KSB (pump technology), Lamtec (bms systems), M&S (burner systems), Hans Hennig (burner systems). For large-capacity boiler components we partner with our partner manufacturer TPK Epo.

Yes. MIK Projekt is a long-standing authorized SAACKE distributor and service partner — SAACKE is a leading global manufacturer of industrial and marine burners, combustion systems, and control automation, with over 90 years of tradition.

Complex projects are led by a named project manager, a lead process engineer, and a coordination team that tracks all interfaces. For the most capital-intensive projects we use CFD modeling, FEA calculations, HAZOP/SIL analysis, laser 3D scanning of as-built conditions, and notified-body coordination for PED CE marking.

Guaranteed 24-hour response time, quarterly or annual preventive inspections, priority parts access, remote monitoring (where applicable), continuous work documentation, and operator training. Extended equipment warranties are available for clients under contract.

Yes. We currently have an open position for a burner service technician where candidates without prior experience are welcome — we provide complete training. We are generally open to juniors in technical fields (mechanical, electrical, automation) and invest in their long-term development.

Five steps: (1) online application with CV, (2) internal application review, (3) online interview (~45 minutes, 1–2 weeks after application), (4) in-person interview (~90 minutes), (5) contract offer — feedback is provided on the day of the interview, the contract draft shortly afterward.

Basic application includes CV (PDF/DOC/DOCX), optional motivation letter, and contact details. For specific positions we may request additional certificates (e.g. driver's license, welding certifications, employment evidence). For service positions, a category B driver's license and basic English are mandatory.

Yes. We welcome unsolicited applications in all technical and commercial areas. Send your CV and motivation letter to office@mikprojekt.com — we review all applications and contact you when a suitable position opens up.
