Airedale has launched OptiChill, a new range of large capacity, high efficiency, air-cooled screw chillers. OptiChill has a small footprint and offers a raft of options providing a high degree of flexibility to meet a diversity of applications.
Offering 500kW to 1100kW nominal cooling capacities across dual independent refrigeration circuits, OptiChill has been optimised for use with R134a refrigerant. A choice of 78 model permutations is available through the range. Thirteen model sizes each offer a Standard and a High Efficiency Range and three low sound level variants in each range.
The very best components are selected for optimum operating efficiency and combine to give EER values of 3.0 or more at Eurovent conditions and ESEER values above 3.5.
Each of the two high efficiency, top-of-the-range compressors modulate to accurately meet cooling load and are complemented by economisers, electronic expansion valves and super-efficient heat exchangers to enhance system performance and efficiency.
The shell and tube evaporator is the best ever presented by Airedale and offers extremely high evaporating temperatures for a given supply water temperature. Condenser coils have larger surface areas to provide greater heat exchange.
