Compressor: Bitzer US Inc.
Bitzer US has started production on its new Ecoline of reciprocating compressor. The company says the new series is transferring all the advantages of the proven Ecoline series for R134a refrigerant to an even broader range of applications in order to provide customers with added value. The compressors are approved for R134a, R404A, R407A, R407C, R407F, and R507A, and are offered in sizes ranging from ½ HP to 50 HP. The series has higher efficiency levels and simultaneously expanded application limits. It can also still fit into existing systems as a replacement. The coefficient of performance was improved throughout the series by 6% (at nominal rating points) and, at low condensing temperatures, which are important for seasonal efficiency, the increase was up to 12%. The new Ecoline compressors with motor version 2 are now universal refrigeration compressors – for full applicability in low temperature applications and medium temperature applications. Motor versions 1 or 3 are provided for heat pumps, medium temperature applications with R134a, and special applications.
