Power Compressor Company
As a Power Compressor Company we make it our business to be on top of our game, to know what is happening in the industry, to know how to repair semi-hermetic and hermetic compressors, streamline and make more efficient a current cooling system, and to support all we do by way of repairing, servicing, exchanging, renting and remanufacturing power compressors.
To this end we stock and supply spares and parts to industry. PCE is invested in engineering to perform radical testing of both screw and reciprocating compressors, semi-hermetic or hermetic. PCE can also repair hermetic compressors (sealed or welded closed).
What is a Remanufactured Compressor?
A remanufactured compressor is a compressor that has been stripped down to its component parts, cleaned, machined where necessary, new parts supplied and rebuilt to the original manufacturer’s standard.
You’ll find that the cost of this is far less than buying a new compressor and yet you can still enjoy the benefit of many years of excellent service. At PCE all of our remanufactured compressors carry the same one year warranty as the original equipment.
We have an excellent range of remanufactured compressors ready to exchange, or you can ask us to remanufacture your own compressor. The choice is yours.
What different types of remanufactured compressor do you get?
Power Compressor Exchange remanufactures many different types of compressors. Some of the more common mechanical compressors are Screw, Reciprocating and Centrifugal. These can be powered by electric motors, steam turbines or gas turbines. They can be either hermetic (welded closed) or semi-hermetic (bolted together).
Extensive engineering services
We specialise in overhauling industrial compressors of all kinds, including hermetic and screw machines.
Before we commence work, we provide a fully comprehensive inspection report. When your compressor arrives for re-manufacturing, the procedure is as follows:
- Examine it carefully and take it apart
- Strip all parts, clean them with chemicals and inspect them
- Remove all worn or damaged parts and replace all gaskets and seals
- Replace reed valves, piston rings, cushions, thrust-washers, valve springs
- Check dimensions of crankshaft and pistons with a micrometer
- Rewind the electric motor
- Assemble to original specification and standard
- Test thoroughly – temperature, pressure, electrics, mechanicals, oil pumps
The result is a high-quality compressor that’s ready to perform optimally and – equally as important – safely.
Our workmanship is guaranteed
Our repaired and exchange units carry the same one year warranty as the original manufacturer. We also offer an extended warranty.
Remanufactured screw compressors
The tight tolerances involved in screw compressors make them difficult to remanufacture correctly. Power Compressor Exchange is an industry leader in remanufacturing screw compressors.
Our skilled PCE technicians work with great care, especially with rotor pairs, as any deviation outside the tolerance will cause the compressor to fail. Each make and model of screw compressor has its own set of specs which must be met in order to function properly. We make sure these standards are met.
Reciprocating compressors use pistons driven by a crankshaft. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines.
A reciprocating compressor is used to deliver a small volume of refrigerant at a very high pressure. It is usually a semi-hermetic compressor which simply means that it can be serviced easily because the casing is bolted together rather than welded.
Small reciprocating compressors are common in automotive applications, usually used for intermittent duty. Household, home workshop and smaller job site compressors are most often reciprocating compressors with an attached receiver tank.
Larger reciprocating compressors (over 750 kW) are found in industrial and petroleum applications. Discharge pressures can range from low to very high.
In certain applications (such as air compression), multi-stage, double-acting compressors are probably the most efficient. They are typically larger and cost more than comparable rotary units.
The centrifugal compressor achieves compression by applying centrifugal force to an air mass. It uses a rotating disc to force the gas to the rim of the impeller, increasing the velocity of the gas. A diffuser (divergent duct) section converts the velocity energy to pressure energy.
The few moving parts in a centrifugal compressor make it popular in the industry. It is also very energy efficient and delivers a higher refrigerant flow than a reciprocating compressor of similar size. It is hermetically sealed in a single piece welded steel casing which cannot be opened for repair.
Centrifugal compressors are more suited to higher volume but low pressure applications - such as those that use ventilation fans, cooling units and air movers.
These compressors are used mainly for continuous, stationary service in industries such as oil refineries, chemical and petrochemical plants and natural gas processing plants. Their application can be from 75 kW upwards. With multiple staging, they can achieve exceptionally high output pressures.
Many large ski resorts use centrifugal compressors to make snow. They are also used in internal combustion engines as superchargers and turbochargers, as well as in small gas turbine engines or in the final compression stage of medium sized gas turbines.
