Airedale launches efficient air-cooled chiller range
Airedale’s DeltaChill range of air-cooled R410A chillers comprises 42 models with cooling capacities from 100 to 450 kW. They are compact, quiet and highly efficient, with excellent part-load efficiencies and configuration flexibility.
Optional EC fan technology integrated with smart control logic such as interactive head-pressure setpoint management and compressor sequencing raises seasonal efficiency ESEERs to over 4.5.
The distinctive V frame, modular, coil-fan arrangement substantially improves part-load performance and control and allows easy access to all components for ease of maintenance. Pumps are below the condensers and can be maintained while the system is running.
Sequenced control compressors are applied in a way to significantly increase the efficiency of staged cooling. Up to three scroll compressors can be used on a single refrigerant circuit, or six compressors on two circuits.
There are two sound ranges, Quiet and Extra Quiet — both with AC fan technology as standard. Extra Quiet models have slower fans to minimise noise and acoustically lined compressor enclosures.
Design features include condensing coils with large surface areas, electronic expansion valves, chiller sequence management and optional Energy Manager.
An optional inverter-controlled pump and electronic flow meter combine to offer the ultimate in water-flow control.
