Analyzing ECOLINE VARISPEED model 4TES-12.F4Y
The BITZER ECOLINE VARISPEED series extends the trendsetting qualities of the ECOLINE compressors with a new series of integrated frequency inverters (FI) for stepless capacity control. This inverter is solidly flanged onto the compressor's motor cover and is cooled by suction gas, which eliminates the need for a fan and ensures maintenance-free operation. Key benefits include a cooling capacity increase of approximately 45% compared to fixed-speed operation (at 60 Hz) and an infinitely adjustable cooling capacity ratio of 3.5:1. This stepless control significantly reduces suction pressure fluctuations and cycling frequencies, leading to substantial energy savings and high system efficiency. The series also features a solid, speed-proof drive gear and a universal refrigerant range, including low GWP options.
