Petra’s air cooled liquid chillers (APSa) with a wide range of capacities and exceptionally high efficiencies, were designed to meet customer requirements for a variety of applications.
Petra APSa chillers offer state of the art low sound, high quality and reliability, optimized performance and a compact physical footprint.
Petra APSa 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.
- The APSa series meets or exceeds the new ASHRAE 90.1 efficiency levels at both full and part load efficiency.
- The APSa chillers offer low sound power levels, measured in accordance with the BS ISO 3744 standard. The low sound power levels make the APSa ideal for sound sensitive applications such as schools, hospitals, and sites located in residential neighborhoods.
- The APSa 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 APSa 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.
- Petra introduces the APSa chillers with nominal kW of 2110, 2040 & 1935 (nominal tons of 550, 580 & 600), with a length of 14400 mm (567 inch) as a single piece unit with single power entry. This unique single unit design provides the largest capacity in one chiller model with a compact footprint.
- APSa chillers are designed with Microchannel (MCHE) condenser coils which are cost effective compared with traditional coil design. Copper tubes aluminum fins and copper tubes copper fins condenser coils are also available with your choice of corrosion resistance coating finish.
- 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.
