2 OVERVIE hy choose tandems? A tandem configuration reduces operating costs through greater capacity control and lower power consumption. Staging the operating sequence of the compressors allows system capacity to match system load. The unloading of conventional fixed speed compressors imposes a serious efficiency penalty at part load or low load conditions. But in a tandem installation, an individual compressor can be switched off while the other compressor continues to run, delivering full capacity and full load efficiency. hy choose Danfoss tandems? Tandem compressor systems present certain design challenges oil equalization, proper oil return, and pipe configuration. Field erected systems can not effectively manage these issues. To ensure highly efficient and long running tandem systems, choose Danfoss. Designed and tested to effectively manage noise, pipe vibrations and oil management, Danfoss tandem scrolls manufactured in North America ensure optimal performance along with these additional benefits: 100% proof-pressure testing and mass spectrometer leak testing of entire assembly Oil equalization system designed for correct performance and reliability throughout the entire operating envelope Overall cost savings to the OEM compared to in-house assembly Oil equalization systems ensure proper oil balancing between compressors Rail mounting tested to protect against vibrations and noise Other standard features: Suction line insulation Crankcase heaters Schrader ports (for P and P cut-out switches) 2
