Independent screw-compressor service - every major brand, one contract
Modern Tech Group is a brand-independent service provider for industrial screw compressors 4-75 kW. That means one maintenance contract covers your Atlas Copco GA, Kaeser BSD, Ingersoll Rand R-Series and CompAir L-Series without routing each machine through a different OEM distributor. For a plant with a mixed fleet, that is typically 20-30% cheaper than three parallel OEM contracts.
Every visit ends with a signed English report listing measurements taken (differential pressure, discharge temperature, oil condition, vibration on the airend housing), parts consumed and next recommended intervention. The report format is unchanged across brands.
How the service works for multi-brand fleets
- Unified maintenance plan across all compressor brands on the same site
- OEM-equivalent parts sourced from ISO/TS-16949 suppliers, priced in EUR
- Genuine parts on request for equipment still under manufacturer warranty
- Overhaul of screw airends in our Radom workshop - bearings, seals, rotor regeneration

Screw compressors (rotary screw, both oil-injected and oil-free) are the workhorse of Polish industrial compressed-air rooms. We service every major brand - Atlas Copco GA / G / ZR / ZT, Kaeser SK / BSD / CSG, Ingersoll Rand R-Series and Nirvana, CompAir L-Series and DH, Boge S / SL / SF, Almig Combi, Airpol, Renner RS-M - from a single Radom base with mobile teams covering Mazowsze, Świętokrzyskie, Łódzkie, Lubelskie and Małopolskie in day trips.
For clients further afield (Silesia, Wielkopolska, Pomerania) we run a scheduled rotation model: preventive maintenance is grouped by region, dispatched Tuesdays and Thursdays, keeping travel cost per visit low. Emergency calls anywhere in central and southern Poland are on the road within 2 hours of confirmation, on-site the same day if the call comes before 12:00.
Why a specialist screw-compressor service, not a general mechanical shop
Air-end diagnostics before overhaul commitment
The 'is the air-end really worn out or is it the inlet valve' question is a five-figure decision. We diagnose with vibration analysis, oil particle count, and controlled pressure ramp tests before recommending an air-end swap. In roughly one third of cases the customer avoids an overhaul that a less-specialised shop would have sold them.
Oil-free screw competence (ISO 8573-1 Class 0)
Oil-free two-stage screws (Atlas Copco Z-Series, Kaeser CSG, CompAir DH) require dry-side rebuild skills that most general workshops lack. We rebuild Z-Series air-ends in our Radom facility with OEM-spec torque and clearance protocols, and verify class-0 output on the customer site.
Controller and VSD retrofit
Older fixed-speed screws can often be retrofitted with variable-speed drives at 30-40% of the cost of a new compressor, cutting energy bills 20-35% on typical duty cycles. We size, install and commission Danfoss and ABB drives with matched control-system integration.
Multi-brand fluency saves you a second service contract
Compressor rooms accumulated over 20 years typically hold two or three brands. Rather than signing separate contracts with each OEM, one contract with us covers all of them - with a single point of accountability when things go wrong.
Site reports engineered for group CMMS
Post-service PDF reports in English (or German on request) with the exact field structure that SAP PM, IBM Maximo and Infor EAM ingest. Your group maintenance planner does not translate or re-key anything.
FAQ - industrial screw-compressor service
How do I know when a screw compressor needs an overhaul vs targeted repair?
Symptoms alone are unreliable. The honest test is: oil particle count trending up over 3 consecutive samples, air-end vibration signature deviating from baseline, and inability to reach set pressure at nominal draw. If two of those three are positive, an overhaul discussion is legitimate. If only one, targeted repair almost always resolves it.
What is the realistic lifetime of an industrial screw compressor?
For a maintained oil-injected screw running 4,000-6,000 h/year: 60,000-80,000 h before first air-end overhaul, 120,000-160,000 h total useful life. Oil-free two-stage machines: 40,000-50,000 h before major overhaul, 100,000 h+ total. Neglected units die much earlier - usually from oil starvation or intake contamination, not age.
Do you handle OEM warranty work?
For most current-generation Atlas Copco, Kaeser and Ingersoll Rand machines, third-party authorised service does not void warranty provided documentation is complete. We keep the warranty paperwork clean. For units under first-year manufacturer coverage we can act as your technical proxy during OEM warranty claims.
Can a VSD retrofit really pay back that fast?
On a compressor room running one 55 kW screw at 60-70% average load, a VSD retrofit typically pays back in 14-22 months at Polish industrial electricity prices (0.65-0.85 PLN / kWh in 2025). At lower average load or higher electricity price the payback shortens further. We calculate site-specific payback before quoting.
