Refrigeration Compressors & Components

Sunnen has set the standard for refrigeration compressor honing solutions. Sunnen supplies solutions for compressors large and small, for cooling systems for large buildings to smaller room-sized air conditioners and dorm refrigerators. Compressors require precision bores for the pistons that pump the refrigerant through the refrigeration cycle. Precision bearings used in compressors are also honed to improve life and provide smooth, quiet operation.

A Sunnen honing machine with special fixtures is capable of being loaded automatically by robotics for high production. Abrasives can be tailor made to satisfy the most demanding requirements of size, surface finish, and abrasive life. Fixtures are designed for quick load-unload cycles to improve throughput.

Like other types of compressors, refrigeration compressors use pistons or other methods to compress refrigerant gas or vapor and deliver it to the condenser. Refrigerating compressors typically operate with superheated vapor associated with the operating conditions of refrigerating machines. These compressors require precision bores for the pistons so vital to the refrigeration cycle. Sunnen can provide solutions for refrigeration compressors of any size or application.

Sunnen produces the industry’s largest selection of honing machines – horizontal or vertical, single or multi spindle, automated or manual, standard or integrated – and our systems are designed with a focus on reliability, flexibility, and ease of use.
