BITZER has introduced the ‘New ECOLINE’ reciprocating compressor series for use with a variety of refrigerants.
As well as R134a, R404A, R407A, R407C, R407F, R507A, hydrocarbons and the new HFO and HFO/HFKW mix can also be used.
For high-pressure R410A refrigerants, special ECOLINE compressors can be specified.
Bitzer claim the ‘New ECOLINEs’ incorporates all the benefits of the original ECOLINE series for R134a and applied them to a much wider range of applications.
Furthermore, it’s claimed they offer higher efficiency and can be used as a replacement part within existing refrigeration systems. The coefficient of performance (COP) has been improved throughout the series by 6 per cent in terms of the usual nominal points and as much as 12 per cent for the low condensing temperatures important for annual capacity (seasonal efficiency).
The compressors with motor version 2 are now universal refrigeration compressors for full low and medium temperature applications. For example, when using R404A this has an evaporation temperature of up to 0°C, even at tropical ambient temperatures. Motor versions 1 and 3 are provided for heat pumps, medium-temperature applications with R134a, and special applications.
Each ‘New’ ECOLINE is compatible with its predecessor as it features an unaltered mounting hole pattern and the same pipe connections. A number of design changes within the compressor have optimized the efficiency (higher cooling capacity with minimal energy requirements).
‘New’ ECOLINE also serves as a basis for all Varispeed compressors and the well-known air- and water-cooled condensing units.
As an optional accessory, BITZER offers tried-and-tested capacity control systems for the entire series. All the compressors are also suitable for operation with external frequency inverters.
