Saying that it is the only screw compressor unit with a five year compressor and 15-year bearing warranty, Emerson Climate Technologies, a business of Emerson, has recently launched its Vilter brand industrial refrigeration compressors in the Middle East and Africa markets.

According to Emerson, the single screw compressor technology with patented parallex slide system, elicits the following advantages:

• Part-load energy efficiency
• Balanced forces (radial and axial) for long life and low maintenance
• Quiet, vibration-free compressor
• All bearings are at suction pressure for reliability
• Widest operating range: 1.2-7.0 Vi

Emerson claims that the introductory seminars and training sessions it conducted have received positive response from interested contractors and end users, thanks to the cost-saving advantages of the single screw technology.

The company also offers Vilter’s 450XL series reciprocating compressors, with applications in the carbonated beverage and ice-making segments. Its features and applications include:

• Ideal for variable loads
• Instant unloading capabilities
• Superior part-load performance
• Inherent variable volume ratio
• Cold starting capabilities with low head pressures <2:1
• Can operate at 100% unloading for extended periods
• Enhanced part-load performance
