Air Technology Australia has introduced a range of scroll chillers, from Clivet Italy, to the Australian market.
The air-cooled scroll chillers, designated WSAT-XSC2, deliver full-load efficiencies the same as screw chillers. But these high efficiency models yield much better part-load efficiencies, making them an ideal choice for air conditioning and process applications where part-load efficiencies are important.
The top of the range ‘Excellence’ model incorporates electronically commutated condenser fans as standard, and is available with many optional features such as full- or partial-heat recovery, free cooling and hydropack with board pump and tank options.
Claiming energy efficiency ratings (EER) of better than 3.1 and ESEER’s of up to 4.6, the range covers capacities from 183kW to 657kW cooling.
All machines have two refrigerant circuits with multiple scroll compressors. Where there are two compressors on a circuit, these are of unequal size, allowing greater efficiencies than with two equal size compressors.
The Clivet Talk control system deploys the machine resources in the most efficient sequence to meet the instantaneous load conditions. With the optional Master/Slave control module multiple chiller installations act as a single chiller with a larger number of compressors yielding even higher part-load efficiencies.
Under the European Eurovent Energy Classification the Excellence model WSAT-XSC2 scroll chiller achieves in the top of Class A and are Eurovent certified.
The WSAT-XSC2 scroll chillers are also available in a ‘Premium’ featuring condenser fan speed control via variable speed drives.
Both versions include acoustic compressor enclosures providing a quiet operation.
