Refrigeration Compressor Supply & Maintenance


ThermaCom supply, repair and service a range of refrigeration compressors from leading brands.

Our compressors can be used within commercial, industrial, food processing and railway applications, and as you can imagine, these types of industries require a very high level of quality control.

We have over 20 years technical and practical experience working on Screw, Semi-Hermetic and Scroll refrigeration compressors, our quality control and consistency for our compressors is one of the highest in the industry. We have a fully functional chiller test rig to test each compressor on.

Fully Checked

fully checked

All compressors castings are fully checked to make sure no damage has occurred. Then, they are stripped back to the bare casting, and any reused parts are fully cleaned and tested.

System Control

The compressors are run-tested on a fully functional chiller with a highly sophisticated and powerful control system (installed by ThermOzone Ltd).

Compressor Performance Comparisons

Of Reciprocating, Scroll and Screw Compressors


One of the many patents on the reciprocal engine was awarded in 1838. Today these compressors are prominent in the refrigeration industry and have been developed to improve their efficiency. The efficiency of these compressors can be increased by 5 - 10% by adding better controls.

Starting Efficiency = 0%

Add a Control = + 10%

Total Efficiency = 10%


In 1905 the scroll machine was awarded one of many patents. The onslaught of this technology was a result of the invention of computers, therefore making this type of compressor more economical and easier to maintain than the previous reciprocating compressor.

Starting Efficiency = 5%

Add an Inverter = + 10%

Add a Control = + 10%

Total Efficiency = 25%


Archimedes could take credit, along with others, for the development of the refined screw compressor. This was invented as a follow on from the computer controlled machine. This compressor started as industrial equipment, but has now been established in the commercial area.

Starting Efficiency = 15%

Add an Inverter = + 10%

Add a Control = + 20%

Total Efficiency = 45%
