Johnson Controls has designed the Sabroe reciprocating ammonia compressor range for use in refrigeration, air-conditioning and heat-pump operations, in even the toughest industrial, marine and offshore applications.
The range includes about 40 different sizes of single-stage reciprocating compressors. Six are also available in high-pressure versions for heat pump operation using ammonia, for CO2 applications and for use with other high-pressure refrigerants, such as R410A. Two-stage reciprocating compressors are also available in eight different sizes for use in low-temperature applications.
The Sabroe ammonia reciprocating compressor range includes both single-stage and dual-stage models.
Variable-speed drive – only using what’s needed
The vast majority of Sabroe compressor models (both reciprocating and screw types) are available with variable-speed drives (VSD) to provide stepless control of your compressor capacity. This helps you achieve maximum cooling effect using minimum energy, as well as keeping operating costs to an absolute minimum. The combination of a frequency converter, a VSD motor, and the UniSAB integrated systems controller makes it possible to run the drive motor at speeds that match the load at any given time. This enables you to reduce energy costs by as much as 30 percent compared with traditional fixed-speed compressors.
