  Modular Chiller


• Wide Range of Capacities: 10-60 Ton capacity range, all AHRI certified

• High efficiency design up to 10 EER at AHRI conditions 

• Compact design

• Easy installation and maintenance


Petra introduces compactness, reliability, redundancy, efficiency and serviceability through its air-cooled modular chillers, which are available in the range of 10-60 ton per module. And can be combined together up to 16 modules in cooling or heating mode.

In addition to the new construction jobs, modular chillers can be considered as a perfect solution for the renovation jobs where it is too expensive to repair or operate an existing system. Modular chillers are lower in installation costs, operation cost and maintenance cost, in addition to the wide variety of combinations that can be enhanced with the modular chillers, and possibility of future expansion.


• Each module is factory charged with non-ozone depletion R-410a refrigerant

• More reliable design is provided by using dual scroll compressors with independent circuits for each module, in addition to using stainless steel
  brazed plate, hi-efficiency heat exchanger

• Each module can be isolated by water isolation valves to enable maintenance for other modules for redundancy issues

• All module components are accessible and laid out in a way that enables the user to make full maintenance without disassembly of modules

• Unit design offers the user to add additional future modules and expand the unit to have more capacity if needed

• Modules are flexible to be installed at site as back-to-back or side-by-side, based on site and space requirement, with one set of common headers

• Available in heat pump and capable to provide hot water up to 55 C° (130°F), in addition to providing chilled water

• Modules can be operated in case of master controller failure

• Communication with BMS systems is available (BacNet, Modbus, Lon works)

• Additional factory installed options are available, like: Manual or Automatic Water Isolation Valves, Hot Gas Bypass, Head Pressure Control, Liquid
  Receiver, Suction Accumulator, Water Differential Pressure Switches and Condenser Coil Coating

All models specifications are subject to change without prior notice.
