Scroll compressors for use with A2L refrigerants
ORBIT (MODEL RANGE VL) and ORBIT+ scroll compressors from BITZER have been ap- proved for serial production for use with the re- frigerants R454B, R452B and R32 and are also suitable for operation with A1 refrigerants.
This makes BITZER the first manufacturer in the world to supply scroll compressors with dis- placements of between 20 and 80 m3/h (50 Hz) for use with A2L refrigerants. These have only low flammability ratings and a low GWP.
The familiar ORBIT series in the VA model range will continue to be available for opera- tion with A1 refrigerants. ORBIT and ORBIT+ are already integrated into BITZER software ensuring they can be quickly and easily config- ured by customers.
BITZER customers will particularly benefit from the A2L approval of the ORBIT (model range VL) and ORBIT+ compressors: both series provide several years of planning security due to
the low GWP values of the refrigerants R454B, R452B and R32.
Before they were approved for serial produc- tion, the ORBIT and ORBIT+ scroll compressors demonstrated their quality and future-proof compatibility in extensive tests. In addition, they have been successfully qualified by OEM cus- tomers in their qualification programs.
The ORBIT and ORBIT+ compressor models feature displacements of between 20 and 80 m3/h (50 Hz) and are designed for air condi- tioning systems and heat pumps in particular.
Their strengths include a wide application range, their high energy efficiency and a low noise level. All compressors in the series can also be operated at a fixed speed or used with an ex- ternal frequency inverter with variable speed (35 to 75 Hz). ORBIT and ORBIT+ scroll compressors can also be equipped with the BITZER Advanced Header Technology (BAHT), providing custom-
BITZER's Advanced Header Technology System (BAHT).
ers with hundreds of potential tandem and trio assembly combinations.
With the ORBIT Portfolio, OEMs can tailor of- ferings to their customers, whereby the construc- tion and manufacturing processes in the system construction can be designed largely the same.
This saves OEMs significant costs in develop- ment and production.
As the ORBIT and ORBIT+ series feature identi- cal connection sizes, there is less design, produc- tion and logistics work involved in the develop- ment of a new generation of systems. This provides OEMs with maximum flexibility and efficiency.
