Abstract
Taking into account all the main advantages and disadvantages of the considered types of compressors, Bitzer has created a new series of Octagon reciprocating compressors, in which, in order to improve them, a number of essential parameters have been modified, including: smooth running and noise characteristics, efficiency, performance controllability, overall dimensions and weight, cost.
