The PRIME-D series air-cooled chiller units are equipped with high-efficiency R410A refrigerant with zero ozone depletion potential and dual-scroll compressors. Due to the dual compressor design, the device can operate at half capacity in situations where the cooling demand is low, significantly reducing electricity consumption. Additionally, in the event of a failure in one of the compressors, the unit continues to operate at half capacity, preventing a complete process shutdown. Compared to completely independent units, they have lower initial investment costs. Furthermore, they have general features such as high temperature sensitivity, optional colored touchscreen control panel, and easy and fast installation thanks to the integrated hydraulic module.
