Compressor Reconditioning. When you have determined that your refrigeration or air-conditioning system has a problem with the compressor, it may be less of a problem than you think.

Reconditioned refrigerant compressors can prove to be a cost effective alternative to purchasing a new compressor with minimal down time.

At this point, in order for you to determine if compressor reconditioning is for you, it is valuable to give you information on the reconditioning procedure for both open drive and semi-hermetic compressors.

When your compressor is received at Our Auckland Base it is recorded and then disassembled to completely assess the extent of damage. In the compressor the motor is removed and tested , or in the case of open drives the shaft seal is tested that it meets manufacturers specifications and/or current draw. Compressor parts such as pistons, rods, rings and crankshafts are sized to check they meet manufacturers rigorous technical standards. Those parts that are worn or damaged are discarded and quoted for replacement. The oil which has been drained from the sump is checked for both quality and quantity and the bores are gauged and checked for damage or wear. All damage is recorded, including damage to heads and bolts, and a final quote incorporating parts and labour is drawn up for the client. Compressor spares for the most popular models are carried ex stock. Those that are not, are sourced from suppliers and a time frame for sourcing them is incorporated into the quotation.

All jobs are quoted and a price is faxed to the client, prior to their approval. At this time, you the client can decide whether it is in your best interest to continue with the job. If you decide not to continue only a minimal charge to cover assessment and quotation is charged for the job. In most cases it proves to be cost effective, otherwise you will be advised. A time frame for the rebuild is also advised in order to minimalise down time.

At this point a cause of failure is fairly evident, which is advised to the client to help with their re-commissioning of the rebuilt machine.

On approval of the job an order number and any special instructions from the client is attached to the job.

The disassembled compressor body is cleaned and degreased in a carefully and constantly monitored cleaning tank to remove any and all existences of dirt or foreign matter.

The body and its cylinders are examined and gauged to meet strict OEM specifications, honed and polished. The cylinders are strictly measured and machined to manufacturers specifications.

All valve plates are re-ground or replaced to meet manufacturers dimensional and operational specifications. The motor, if quoted for rewinding is rewound, varnished and tested to meet electronic specifications, ensuring quality, reliability and maximum performance.

Our technicians then rebuild your compressor in our specially designed assembly room, using new parts that have been quoted for replacement. Valve reeds, rings and all gaskets are replaced as standard, to ensure maximum performance. The compressor is then filled with oil.

Once re-assembled the compressor is put through specialist dehydrating and run tested under load to check that it meets manufacturers strict technical standards and current draw and oil pressure. Once checked and approved, the compressor is painted and transport is arranged back to the clients address ready to be re-installed in their system. All work is covered by our 3 Month standard parts and labour warranty.

Strict adherence to OEM measurements and standards at each step ensures ' Good as new' quality and performance.
