New Ecoline 'unlocks full CO₂ benefits'


07 June 2023

Compressor manufacturer Bitzer says food manufacturers with large cooling requirements can now harness the full benefits of environmentally friendly carbon dioxide-based refrigeration following the release of its new high capacity Ecoline CO₂ unit.

The 8-cylinder reciprocating compressor for transcritical CO₂ applications is said to deliver outstanding energy efficiency and ultra-low global warming potential (GWP) in a compact footprint that is easy to integrate on site.

In the past, high cooling loads could only be delivered with transcritical CO₂ systems by using multiple smaller compressors to achieve the desired refrigeration output. The new Ecoline compressor enables large cooling loads to be met with a single unit, saving space, improving energy efficiency and performance, and simplifying service and maintenance.

Kevin Glass, managing director of Bitzer UK, said: “Using transcritical CO₂ in large refrigeration systems has a number of advantages. It’s a natural, non-toxic refrigerant which enables compact system dimensions, while future-proofing operators against changes in F-gas regulations, thereby ensuring regulatory compliance and protecting capital investment.

“The new 8-cylinder unit brings all these benefits together in a single, compact package that is even more energy efficient. For food manufacturers with large cooling loads, it’s an excellent all-round solution.”

Bitzer adds that the new unit is around 10% more energy efficient than smaller 6-cylinder compressors currently available, reducing energy consumption and emissions, and cutting running costs throughout the lifetime of the equipment. 

Available in two motor variants with displacements between 69.4 and 99.2 m3/h, it is also equipped with Varistep mechanical capacity control for higher efficiency at part load operation.
