K-SERIES

Multiple Applications 

Variable Load Capability

Simplified Package Design

Supports a Wide Range of Pressure Conditions

Multiple configurations are available in drive type (direct/belt) and refrigerant compatibility ( A m m o n i a , P r o p a n e a n d F l u o r o c a r b o n refrigerants). A compressor suited to many different refrigeration applications,

A wide rotational speed range from 800 to 1800rpm provides a powerful output capacity.

Hydrau l ic l ines fo r capac i t y cont ro l a re incorporated into the casing design, allowing s i m p l i f i e d p a c k a g e d e s i g n s a n d e a s y maintenance.

The components are designed for high pressure applications and a wide range of operating conditions. The K series can be used in demanding applications such as high pressure systems and heat pumps.
