CIAT Ozonair Ltd has launched AirDuo, a new range of split air-to-air cooling units and reversible heat pumps designed to combine high efficiency with environmental friendliness. Suitable for a wide range of applications including shops, offices and light industrial buildings, the range comprises 14 models with cooling capacities from 20 to 135kW and heating capacities from 22 to 145kW.
All models employ R410A refrigerant and have casing made from polyester-painted, galvanised sheet steel panels on self-supporting frames. Depending on size, models also feature either one or two independent refrigerating circuits and one or two new generation high output scroll compressors.
External units have fin and coil type high efficiency air exchangers, which offer great compactness in ‘U’ or ‘V’ configurations.
Operation of units is by means of new, advanced technology Avant Pro (Carel PCO3+ PGD1) control units. These provide automatic control of the fans to achieve optimum all-year-round performance with the option to select low noise priority.
