DESCRIPTION:

Petra’s water cooled liquid chillers (WPSa) with a wide range of capacities and exceptionally high efficiencies, were designed to meet customer requirements for a variety of applications.Petra WPSa chillers offer state of the art low sound, high quality and reliability, optimized performance and a compact physical footprint.Petra WPSa chillers with semi-hermetic screw compressors and R-134a HFC refrigerant are 100% factory tested and commissioned to ensure efficient performance at specified operating conditions.

Highlights:

The WPSa series meets or exceeds the new ASHRAE 90.1 efficiency levels at both full and part load efficiency.The WPSa series is available as a door way or extended chassis designThe WPSa chillers feature compact footprints and are suitable for close-spacing installation to serve the areas that have space constraints.To ensure the best performance, all the chillers in the WPSa series are factory-run tested, produced in an ISO 9001-2015 listed manufacturing facility & certified according to AHRI standard 550/590.Installation is made quick and easy with complete factory wiring, easy lifting provisions, factory installed options and start-up. To eliminate potential start-up problems, a complete factory- test run is performed on each unit.Suction lines are insulated with closed cell foam insulation, then wrapped with a special protective material and finally epoxy coated. This gives further protection for the insulation against weather and other factors.Other exposed copper pipes and headers are epoxy coated after being cleaned, to maintain pipe material and brazing protected against external conditions.Petra paint is certified according to ASTM 117 A&B 5000 hours salt spray test.
