Air Cooled Modular Chiller

Air Cooled Modular Chiller

Petra introduces compactness, reliability, redundancy, efficiency and serviceability through its air-cooled modular chillers, which are available in the range of 35 kW (10 Tons) – 211 kW (60 Tons) 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

  • The chiller module has an engineered compact design to save space and to enable easier lifting, handling & installation
  • High efficiency design up to 10 EER at AHRI conditions
  • 35-211 kW (10-60 Tons) capacity range, all AHRI certified
  • Module acoustical design provides low sound level through using low noise condenser fans and heavy unit structure
  • 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 use 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
  • Each module has its own individual control panel. And all modules can be mastered in one controller
  • Modules can be operated in case of master controller fails
  • Each module is factory charged with non-ozone depletion R-410a refrigerant, which offers better efficiency and higher capacity
  • Dual scroll compressors with independent circuits for each module
  • Stainless steel high efficiency brazed plate heat exchanger
  • Heavy gauge galvanized steel casing, electrostatic powder paint, 5,000 hr salt spray test
  • C-channel base prepared for lifting by heavy duty eye- bolts
  • Wire mesh is added for coil protection
  • Each module can be isolated by water isolation valves to enable maintenance for other modules for redundancy issues
  • Available in heat pump and capable to provide hot water up to 54ºC (130ºF) in addition to providing chilled water
  • Single point power entry is available for multiple module units to make site work easier and less cost
  • Communication with BMS systems is available (BacNet, Modbus, Lon works)
  • Manual or Automatic Water Isolation Valves
  • Hot Gas Bypass
  • Head Pressure Control
  • Liquid Receiver
  • Suction Accumulator
  • Water Differential Pressure Switches
  • Condenser Coil Coating
  • Low sound compressors jackets
