Air-cooled Scroll Chiller (R-407c)
   
  Air-cooled Scroll Chiller (R-407C)  
  Introduction  
 

Air-cooled scroll chillers are available in capacity range 22TR to 120TR in one single enclosure. Utilizing refrigerant R-407c as working fluid, chillers have been designed and manufactured to meet the requirements of tropical climatic conditions and specifically for outdoor installations.

Quiet :
Aerofoil design of condenser fan makes low noise which ensure silent operation.

Reliable :
Scroll compressor set have fewer moving parts leads to Reliable operation.

Controls Flexibility :
Protocol Selectability DDC controls integrate into your building automation system of choice. And it's simple to achieve interoperability using open, standard protocols such as Modbus or BACnet®.

 
  Features  
 
  • Air-cooled Scroll Chillers are designed to provide engineering excellence in comfort air conditioning and industrial cooling with a superior combination of energy saving, performance, application flexibility, ease of service & maintenance and withstanding extreme ambient temperatures. These chillers incorporate a wide range of features including :
  • Eco-friendly R407C Refrigerant.
  • Microprocessor controller, which monitors analog and digital inputs to achieve precise control & protective functions of the Air-cooled Scroll chiller units. The microprocessor controller is complete with all the hardware and software necessary to control the chiller unit and ensures its efficiency and reliability.
  • Compact unit design and excellent serviceability.
  • High Energy Efficiency Ratio (EER) hermetic scroll compressors.
  • Single point power connection to minimize job site installation cost and time.
  • Completely wired control panel with the advanced microprocessor controller that provides all the necessary operations and safety controls.
  • Made ready connection for remote ON / OFF switch and local Alarm output.
  • Independent and Tandem refrigeration circuits.
  • Compressor connections are Direct on Line (DOL) for all models.
  • Low noise condenser fans with direct drive arrangement with rolled form venturi design to eliminate airflow recycling & short circuiting.
  • Propeller type fans with die cast aluminum hub provides long life aerodynamic design, ensure lower noise.
  • All condenser fan motors are Totally Enclosed Air Over type (TEAO) with class ''F'' winding insulation.
