Hitema - Model PRP Series - Modular Air-Cooled Liquid Chillers with Axial Fans
From Propane Chillers
PRP SERIES are aircooled liquid modular chillers with natural refrigerant R290. R290 represents one of the most attractive alternative to the traditional HFC refrigerants characterized by high GWP. This natural fluid has a zero ozone depletion potential (ODP = 0), a negligible direct greenhouse affect (GWP = 3) and also has very high coefficient of performance. As a result, the life cycle costs are significantly lower compared to similar systems with traditional HFCs. These units are designed to reduce the refrigerant charge per circuit and ensure high unit redundancy. A detailed safety-oriented design ensure safe operation of the systems at every working conditions. All models are optionally available with free-cooling, at low ambient temperatures the free-ccoling replaces the compression refrigeration resulting in a high increase energy efficiency. Designed for outdoor installation only.

Advantages
- Propane is not subject to the limitation of F-Gas regulation
- Propane is a pure gas, not a mixture; as a consequence of this it doesn’t present any of the glide problems that have been found in other synthetic refrigerants
- The use of Propane offers a very wide range of working area: it can be used both in refrigeration and air conditioning
- Its low density and its thermodynamic properties allow a reduction of the charge and relatively low working pressures
- High efficiency of Propane: this refrigerant proves to be more efficient than the other synthetic refrigerants normally used
