Centrifugal Chillers

Centrif. maintenance and shaft seal replacement - Chiller repair

The Service and Maintenance of Centrifugal Chillers

Centrifugal systems are not positive displacement systems like screw and reciprocating compressors. Therefore, they have a lower volumetric efficiency. They are used in applications such as large industrial processes or district cooling

Shaft Seal

The compressor in the picture left is open drive. The shaft seal needs to be replaced when it shows signs of wear. Because the issue is noticed during the maintenance, the repair can be arranged to take place during a factory shut down

Tube Fouling

This lowers efficiency and can lead to safety shut down and loss of production. A visit can be arranged to dismantle the heat exhangers and clean the tubes

Oil Return

On the major maintenance visit the oil filter is cleaned or replaced according to the type. This allows the effective lubrication of the bearings for the high and low speed shaft. The low speed shaft is driven by the motor. The high speed shaft spins the impeller

What We Offer

We have years of industry experience with the Repair and Maintenance of centrifugal compressorsOur re-manufacturing facility is complete with a gantry crane for the removal of compressor components

Case Study

A large centrifugal compressor had been surging under low load at a chemical plant we look after. On start-up the oil pumps pre-lube the compressor bearings but oil pressure was not building up. This is because the oil drops through the worn bearing and out through the compressor

Compressor Re-build

We arranged the lift and shift, then re-built the compressor in our work shop. That was two years ago now and it is still running perfectly

Why Choose Us?

More service- less cost. We have the highest level of technical ability at a reasonable price
