Reception
Once the compressor reaches our workshop it is completely disassembled and the condition of the parts is checked. Parts that do not meet the necessary requirements will be replaced with new parts. The quotation is then drawn up, including an itemisation of any new material required, such as pistons, rods, gaskets etc., and any other work to be done, such as grinding and labour. Finally, a report is produced indicating the possible causes of the fault: seizure due to lack of oil, liquid slugging, phase failure, etc.
Mechanics/grinding
Once the quotation has been accepted, the compressor and all its parts are cleaned.
This is one of the most important parts of compressor repair.
Repairing refrigeration compressors involves cleaning them with specialist products, enabling us to remove all traces of oil, grease, rust and paint, and leaving the compressor looking like new. It is then reassembled and new brand parts or alternative parts are fitted, the latter option making our prices very competitive. Compressors that may need some grinding due to scratched sleeves, rod necks and bearings are machined to adapt them to the manufacturer’s settings.
Electrical/winding
This part consists of the Stator, which is checked and verified. If the windings are burnt, they are rewound with premium-quality material, suitable enamelled copper wire and varnishes that are totally compatible with the freons and oils used in the refrigeration industry.
Test/Controls
Tests performed on the compressor after repair:
Start-up and verification of:
– Oil levels (oil according to the coolant gas)
– Water tightness test
– Oil pump pressure
– Megging of the Winding at 1000 MegaOhms and isolations
– Consumption of ampacity by empty phases
– The compressor is also checked to see if it has travel when it is stopped.
Dispatch
Once the repair has been completed, we load the compressor with the corresponding oil for testing, painting and analysis, and for subsequent dispatch and/or pick-up.
