Vilter Single Screw Compressors

Vilter’s VSM & VSS single screw compressors for industrial refrigeration deliver longer life, higher reliability, and better energy efficiency than twin screw compressors and have fewer moving parts than reciprocating compressors. The key to the single screw compressor’s reliability is in its balanced design. The balanced design results in ultra-low bearing loads with significantly decreased vibration and sound levels.

Description

The inherent balanced design advantages allow Vilter to offer the exclusive 5/15 Warranty, including 5 years on the compressor and 15 years on the bearings. The key to the single screw compressor’s high effi ciency is Vilter’s exclusive Parallex™ slide system allowing the compressor to run at optimum effi ciency through it’s full range of capacity. Providing the highest reliability and unsurpassed energy efficiency.
