Compressor Services

Complete compressor overhauling: every part stripped, cleaned, checked and measured against manufacturer tolerances — then rebuilt to OEM standard with OEM spare parts.

Overhauling

There are few compressors beyond repair

Our compressor overhauling includes a complete strip-down and clean. All parts are checked for damage and all tolerances are recorded and checked against the manufacturer’s recommendations. The compressor is then rebuilt, replacing any worn or faulty parts to the exact OEM recommended standard using OEM spare parts.

Where rotors or crankshafts are found to be beyond the manufacturer’s recommended wear limits, they can be precision machined back to the original standard. From a motor rewind to a complete rebuild including a new crankshaft, there are few compressors beyond repair.

Even complex projects are managed and carried out efficiently. Our service experts have mastery of the technologies used during repairs and overhauls, and professional project management keeps delivery on time and quality at its highest.

Remanufactured compressors

On the shelf, ready for despatch

By monitoring trends and types, Arctic Mount endeavours to hold comprehensive stocks of remanufactured refrigeration compressors ready for immediate despatch. Direct replacements keep downtime to a minimum and help preserve your produce.

If requested, our experienced lift & shift teams can remove the old unit and install the remanufactured compressor, often within hours and with minimal disruption. This service is available nationwide.

Overhauling & stator rewinding

Our own in-house rewinding department

Rewinding is a specialised process, and we place great emphasis on having our own in-house rewinding department. Our rewinding personnel are experts in the field, and a computerised coil winding machine lets us deal promptly with all types and sizes of stators — invaluable in a compressor emergency.

We use only the highest-grade materials for the demands of the refrigeration industry: all varnishes are Freon-proof and insulation is to the highest Class H standard. Rewound stator windings are rigorously tested — flash tested to 2000V to earth, tested on a full load transformer and checked for rotational direction. Ohms readings are recorded and retained.

Warning signs

Signs a compressor needs overhauling

Catching these early often means an overhaul instead of a replacement, and planned downtime instead of an emergency.

Book an inspection

General guidance only. Our engineers confirm the actual cause on site.

01
Knocking or metallic noise
New knocking or grinding sounds usually mean mechanical wear in bearings, pistons, valves or rotors that will get worse under load.
02
Rising vibration
Increasing vibration points to wear, misalignment or loose mountings. Left unchecked it damages pipework and the compressor itself.
03
High discharge temperature
Running hot can come from worn valves, poor lubrication or system problems, and it breaks down the oil and the motor insulation over time.
04
Motor tripping or insulation faults
Overload trips or low insulation readings can indicate a failing stator winding. A rewind is often possible instead of a new compressor.
05
Oil carry-over or oil loss
Oil leaving the compressor starves the bearings. Worn rings or seals and system design issues both need investigating.

FAQ

Compressor service questions

Which compressor brands do you overhaul?

We overhaul and recondition open and semi-hermetic compressors of all major brands, including Trane, Carrier, York, Bitzer, Copeland, McQuay, Hitachi, Grasso, Kirloskar, Refcomp and Hanbell.

What happens during a compressor overhaul?

The compressor is completely stripped down and cleaned, all parts are checked and tolerances recorded against the manufacturer’s recommendations, then it is rebuilt with worn or faulty parts replaced to OEM standard using OEM spare parts.

Do you rewind compressor stators?

Yes. We have our own in-house rewinding department with a computerised coil winding machine, Freon-proof varnishes and Class H insulation. Rewound windings are flash tested to 2000V to earth, load tested and checked for rotational direction.

Can you replace a compressor on site?

Yes. Our lift & shift teams can remove the old compressor and install a remanufactured one, often within hours and with minimal disruption.
