BITZER ECOLINE compressor range operates at lower condensing temperatures and can use a wide range of commonly used refrigerants. BITZER ECOLINE compressors have achieved up to 12% more COP than previous products. Product energy efficiency is improved by further optimizing the design of the compressor valve plate. Reduce compressor internal losses and reduce compressor exhaust pulsation. This series of compressors can also be used in conjunction with frequency converters.
