RAS F Kp

The packaged air cooled chillers of RAS F Kp series are suitable for outdoor installation and are particularly indicated to cool fluid solutions for industrial applications or air conditioning systems of the service industry, where it is necessary to grant excellent performances at very low environmental impact. 

The refrigerant used is propane, a non-toxic hydrocarbon, even at high concentrations, with an almost null ozone depletion potential, negligible global warming potential and thermodynamic properties which allow to reach high efficiency values. 

For this reason the units are designed as group for external installation, in compliance with the European standard EN378 and updates. 

The integrated Free-cooling section allows to partially or totally recovering of cooling capacity from external air without big consumption of energy. Units are equipped with an additional coil crossed by the liquid to be chilled and invested by the complete air flow generated by the condenser fans. 

As soon as the inlet Free-cooling air temperature is low- er than inlet water returning from the plant, Free-cool- ing operation starts.

The benefit obtained by the Free-cooling system is much bigger as much lower is the external air temperature than the temperature value of fluid to be chilled. That’s why such kind of units are suitable to be installed on air conditioning and refrigeration plants located where the weather annual profile is characterized by medium-low external temperatures and where the cool- ing demand is significant and for long periods of time.
