Emerson extends chiller range

Emerson Climate Technologies has extended the product line of its Vilter single screw compressors.

The new VSS-1301 fills the displacement gap with a volume of 1849 m³/h and a 312 mm screw diameter.

Additionally, four new large screws with a diameter of 401 mm reach a maximum displacement of 4200 m³/h. All Vilter screw compressors are usable in booster and high stage applications using ammonia as the refrigerant.

Cooling capacities from 100 kW (Booster) up to 2700 kW (High stage) are covered. All models include standard oil cooling options and can incorporate economized operation for high compression ratio applications.

Emerson says the Vilter single screw compressors have fewer moving parts than twin screw compressors. In addition, the Parallex slide system allows running the compressor at optimum efficiency through its full capacity range from 10 to 100 per cent.
