Water chillers

Specification

For any refrigeration/HVAC application above + 2 deg C, generally water chillers are used.

 

We are the biggest chiller plant manufacturers based in Ahmedabad, Gujarat, India who can offer the most suitable and economically viable automatic water chiller for your Refri-AC application. Looking to the current Global Warming scenario, and the need for sustainability, we always recommend natural and green gas, Ammonia as the primary refrigerant.

 

We are also the dealers of Daikin for their air conditioning products line and also their Freon based water chillers.

Commercial application:

 

Water chillers can be used in comfort cooling and air conditioning of Banquet halls, Malls, Parking lots, Building central air conditioning, etc.

Industrial Application:

 

Water Chillers are used for dairy and food processing, breweries, bottling plants, cement industries, Plastic processing (Tapeline and lamination), Pharma Utlity, Testing labs, Cold rooms / Storages, UPS rooms etc.

Capacities available

 

From 35 kW (10 TR) to 5000 kW (1400TR) ( Make: Daikin or Advance)

Advantages over DX and VRV chillers:

  • Lower life cycle cost
  • Low capital cost
  • Infinite capacity control with best IPLV
  • Precise RH and temperature control
  • Safe operation, isolated utility
  • No ducting work required

Our Special features
