NEWS Green Point extends remanufacturing to transcritical CO 2 compressors Will Pribyl of Green Point UK with the new transcritical test unit Green Point UK has extended its remanufacturing operation to include transcritical CO 2 -based compressors. The service covers all BITZER Ecoline 2, 4, and 6 cylinder transcritical CO 2 compressors, which are deployed in thousands of applications across the UK, including supermarkets, food and drink manufacturers and industrial process applications. Pressure testing is carried out on a bespoke hydraulic test rig, developed by Green Point UK, which is able to test compressor bodies up to 180 Bar. Based on oil, it overcomes the risks associated with conventional pressure testing using air as a direct compression medium. Remanufactured transcritical units are covered by a one-year warranty as standard, with an optional further one-year extension, as for new compressors. In addition to the capital cost and safety advantages, Green Point says a further benefit of the remanufactured units is that, over time, compressors tend to become less efficient due to normal wear and tear. Remanufacturing by Green Point returns units to their original factory specification, reinstating original levels of energy efficiency. General manager Will Pribyl said: "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. For companies operating national estates, with perhaps thousands of refrigeration systems, it could amount to millions of pounds of savings a year."
