Bitzer adds variable-speed drives to Octagon range of reciprocating compressors
Bitzer’s Octagon Varispeed range of reciprocating compressors has a flange-mounted frequency inverter that is cooled by suction gases — making them maintenance free and safe to operate at high ambient temperatures. The control range is from 25 to 87 Hz, and these compressors can be used in compound systems and standalone applications to save considerable amounts of energy over a year.
Other benefits include optimal capacity adaptation and low starting currents.
The Ecoline compressor variant in the Varispeed series offers particularly good scope for substantial energy savings.
With the Varispeed versions of its Ecoline series and the Octagon series, Bitzer will in the future also offer reciprocating compressors for trans-critical CO2 applications with built-in frequency inverters.
There are 15 Varispeed compressors from 24 to 99 m3/h at 87 Hz.
