Bitzer adds CO2 compressor remanufacturing

UK: Green Point UK, Bitzer UK’s remanufacturing operation, has extended its operation to include transcritical CO2 compressors.

A complete service for Bitzer transcritical units can now be offered following the investment in a bespoke hydraulic test rig, capable of testing compressor bodies up to 180bar. Based on oil, it overcomes the risks associated with conventional pressure testing using air as a direct compression medium. The service covers all Bitzer Ecoline 2, 4, and 6 cylinder transcritical CO2 compressors.

“We have been aware for a while of an emerging need among UK customers for a certified remanufactured option as a growing number transcritical CO2 units come to the end of their working lives,” explained Green Point UK’s general manager Will Pribyl. 

“The obstacle has been the high pressures required for full quality assurance testing. Our comprehensive remanufacturing and testing process, overseen and backed by Bitzer, gives total confidence that our transcritical units will perform to specification, with safety assured by certificated testing.

Remanufacturing by Green Point returns units to their original factory specification, reinstating original levels of energy efficiency. Remanufactured transcritical units are covered by a one-year warranty as standard, with an optional further one-year extension, as for new compressors. 

“Unlike most competitors, we fit a new motor to every remanufactured compressor, irrespective of the condition of the existing motor. This can make a big difference to efficiency. With soaring energy prices, it can significantly reduce running costs for an end user with a pack system,” said Will Pribyl

“The UK is one of the first in Green Point’s global network to introduce this service for high pressure CO2 units,” revealed Bitzer UK MD Kevin Glass. “We have played a key role in developing the critical pressure testing technology, and are proud this UK advance has opened the way for what will be an international roll-out of transcritical remanufacturing in the months and years to come.”
