PETRA’s Air-Cooled Smart chillers (PSC) with hermetic scroll compressors with R410a / R407c refrigerants, offer a wide range of sizes to meet customer requirements for different applications.
PETRA’s Smart chillers are designed to meet customer requirements by offering state of the art low sound, reliability, high energy efficiency and small physical footprints. The wide range of cooling capacities and flexible installation arrangement makes them easy to install and maintain.
PETRA’s Smart Chillers (PSC) are designed to be shipped as a complete factory package which are 100% test run in the factory. Unit capacities in this series range from 151 kW (43 Tons) to 1,343 kW (382 Tons) at 50Hz and from 179 kW (51 Tons) to 1565 kW (445 Tons) nominal tons at 60Hz with refrigerant R410a and from 144 kW (41 Tons) to 1,322 kW (367 Tons) at 50Hz and from 162 kW (46 Tons) to 1523 kW (433 Tons) nominal tons at 60Hz with refrigerant R407c. A wide choice of chiller capacities and options are available to meet most design requirements.
PETRA’s Smart Chillers PSC consist of highly efficient low-pressure drop coolers and high quality condenser coils with maximized airflow. Condenser coils are equipped with low noise fans with patented design fan and motor mounting.
PETRA’s Smart Chillers are equipped with an intelligent microprocessor controller to manage the unit’s performance for optimum efficiency at both full load and part load values.
- The PSC series meets or exceeds the new ASHRAE 90.1 efficiency levels at both full and part load efficiency.
- The PSC 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 PSC 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 PSC 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 PSC chillers 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.
- PSC chillers are available with Microchannel (MCHE) condenser coils which are cost effective compared with traditional coil design or with copper tubes aluminum fins and copper tubes copper fins condenser coils 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.
