Green Point UK Extends Service To Include Remanufactured Transcritical Carbon Dioxide-Based Compressors

In a significant technical and commercial development, Green Point UK, BITZER UK’s specialist services arm, has extended its remanufacturing operation to include transcritical carbon dioxide-based compressors.

Will Pribyl, Green Point UK’s General Manager, said “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.”

Remanufacturing operation service extended

The obstacle has been the high pressures required for full quality assurance testing"

He adds, “The obstacle has been the high pressures required for full quality assurance testing. However, following recent investment in a new facility at Green Point UK, we can now offer a complete service for BITZER transcritical units, returning them to full original specification, with quality underpinned by the manufacturer.”

Will Pribyl continues, “It is a live issue for national contractors, many of whom have comprehensive contracts with customers. First-time fix is vital, as call-backs for faults or repairs can eliminate profits. 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.”

BITZER Ecoline 2, 4, 6 cylinder transcritical CO2 compressors

The service covers all BITZER Ecoline 2, 4, and 6 cylinder transcritical CO2 compressors, which are deployed in thousands of applications across the United Kingdom, 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 with one-year warranty

Remanufactured transcritical units are covered by a one-year warranty as standard, with an optional further one-year extension, as for new compressors.

Kevin Glass, the Managing Director of BITZER UK, said “The UK is one of the first in Green Point's global network to introduce this service for high pressure CO2 units. 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.”

Industrial end users adopting transcritical CO2

Industrial end users are now increasingly looking to adopt transcritical CO2

Use of transcritical compressors took off in the early 2000s, as a number of UK supermarkets championed the solution as a low-GWP alternative to high-GWP refrigerants, putting the United Kingdom in the vanguard of the switch to cooling with carbon dioxide.

Industrial end users are now increasingly looking to adopt transcritical CO2 due to the toxicity and flammability issues with ammonia, the traditionally preferred solution for large-scale industrial applications.

Re-manufacturing returns units to original factory specification

In addition to the capital cost and safety advantages, a further benefit of Green’s Point UK’s remanufactured units is that, over time, compressors tend to become less efficient due to normal wear and tear. Re-manufacturing by Green Point returns units to their original factory specification, reinstating original levels of energy efficiency.

Will Pribyl stated, “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.”

Enhanced efficiency

He adds, “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.”
