User manual BITZER ORBIT 8 TANDEM

[. . . ] ORBIT 8 compound compressor assemblies (GSD8 series) ORBIT 8 tandem and trio scroll compressor assemblies consist of two or three compressors, respectively, connected in a parallel configuration and offer advantages over single compressors with equivalent capacity. [. . . ] While the single compressor IPLV* advantage may be up to 15% better than competitive models, in a tandem and trio assembly the benefits are even greater figures. Performance of compound compressor assemblies The performance data of the compounded compressors corresponds to the sum of the performance data of each of the single compressors. For further information on technical design and performance data of single compressors see BITZER Software and brochure ESP-135.
