AIR COOLED CHILLERS FOR OUTDOOR INSTALLATION WITH INTEGRATED FREE COOLING EQUIPPED WITH SCREW INVERTER COMPRESSORS AND AXIAL FANS
Cooling capacity from 308 kW to 1837 Kw
Packaged air cooled chillers of RAH VS F eries with integrated free cooling section are suitable for outdoor installation and can be used to cool glycol fluid solutions for air conditioning or in industrial applications.
Semi-hermetic screw inverter technology allows to reach great efficiency improvements at part load, if compared to the other traditional systems for cooling capacity control.
The integrated free cooling section allows to partially or totally recover 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.
The combination of high efficiency finned exchangers with the thermophysical purity of refrigerant used, almost glide-free during the changes of state, allows having nominal EER near 3 with ESEER above 5 in mechanical operation.
These units have been designed considering limited space requirements and keeping, at the same time, high cooling performances. Such result has been attained with high-quality and up-to-date components.
All units are completely assembled and tested in the factory with specific quality procedures and are already equipped with all necessary hydraulic, refrigerant and electrical connections for a quick installation on site.
Before factory testing, cooling circuits are tested under pressure and then supplied with refrigerant and a non-freezing oil charge.
