OptiChill range Features Key feature: Modulating screw compressors Top-of-the-range twin screw compressors offer high performance coupled with low sound and vibration levels. The compressors modulate to accurately meet cooling load and are complemented by economisers to produce a significant increase in cooling capacity. Airedale’s long experience in combining this technology with other performance-enhancing features such as electronic expansion valves and intelligent head pressure control means that system design is fully integrated and efficiency maximised. Key feature: EC (electronically commutated)...

OptiChill range Options Key feature: Electronic expansion valves Pressure (Bara) The Mollier diagram shown right helps to illustrate how this increase in efficiency is achieved. Reduced condensing pressure EXPANSION By reducing the need for artificially high head pressure, an electronic expansion valve (EEV) typically provides an increase of up to 30% in the system energy efficiency ratio (EER), cutting operating costs accordingly. Cooling Evaporating pressure Increase in Cooling Duty Enthalpy (kJ/kg) Reduction in Compressor Input Power Key option: Closed transition star/delta starting During...
