Types of compressors we overhaul
Our engineers have experience working with a wide range of compressor models and configurations across refrigeration, chiller, and HVAC systems, including equipment from leading manufacturers such as Copeland, Bitzer, Carrier, Danfoss, and Frascold. Chiller and refrigeration compressor overhauls form a core part of our day-to-day operations.
Semi-Hermetic Compressor Overhaul
We carry out comprehensive semi-hermetic compressor overhauls for commercial and industrial refrigeration systems, including those used in chiller compressor overhaul and refrigeration compressor overhaul applications.
Each compressor is fully stripped down, allowing for detailed inspection of internal components including crankshafts, conrods, valve plates, bearings, and motor assemblies. Worn or damaged components are replaced using OEM or high-quality equivalent parts, ensuring reliable performance in demanding refrigeration environments.
Screw Compressor Overhaul
Our screw compressor overhaul services are designed for high-capacity systems operating in demanding industrial environments, including compressors used in chiller compressor overhaul and large-scale refrigeration applications.
The overhaul process includes full strip down and inspection of rotors, bearings, shaft seals, and housings. Components are rebuilt with precision to restore efficiency and minimise internal leakage.
Scroll Compressor Overhaul
We provide scroll compressor overhaul and support services for HVAC and air conditioning systems, including compressors used in HVAC compressor overhaul and smaller chiller applications.
Due to the design of scroll compressors, overhaul is assessed on a case-by-case basis, with repair or replacement solutions provided where appropriate to maintain system performance.
Reciprocating Compressor Overhaul
Our reciprocating compressor overhaul services cover a wide range of applications across refrigeration and HVAC systems, including compressors used in refrigeration compressor overhaul and HVAC compressor overhaul projects.
The overhaul process includes full disassembly, inspection of pistons and cylinders, and replacement of worn components to ensure reliable compression and long-term performance.
Our engineers have experience working with a wide range of compressor models and configurations across refrigeration, chiller, and HVAC applications. Chiller compressor overhauls and refrigeration compressor overhauls are day-to-day
