ARA series air-cooled chillers are units with single, double, four and six scroll compressors according to the relevant capacity with highly efficient R410A and R454B refrigerants with zero ozone depletion potential. In models with multi-compressor structure, the device starts to operate at half capacity when the capacity requirement is low, significantly reducing electricity consumption. In addition, in the event of a failure in one of the compressors, the process is prevented from stopping completely by continuing to operate at half capacity. Initial investment costs are low compared to completely independent devices. In addition, it has general features such as high temperature sensitivity, production with known quality components and color touch control panel that can be offered as standard or optional according to capacity, fast and easy installation thanks to the integrated hydraulic module.
