Water Chillers

Ammonia water chillers are industrial refrigeration systems that use ammonia (NH₃) as the refrigerant to cool water or brine, which is then circulated to provide cooling in various applications (like HVAC, food processing, dairy, or cold storage systems).

These chillers are known for their high efficiency, environmental safety, and suitability for large-scale cooling operations. Ammonia water chillers can provide +1°C to +10°C chilled water.

 

Key Features:

1. Uses Ammonia (NH₃) as Refrigerant

• Natural refrigerant with zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP)

• Non-corrosive to steel and very efficient in heat exchange

2. High Cooling Efficiency

• Excellent thermodynamic properties enable fast and efficient heat removal

• Lower energy consumption compared to synthetic refrigerants (like R134a or R22)

3. Chilled Water or Brine Output

• Provides chilled water typically in the range of +1°C to +10°C

• Can also be configured to circulate brine for sub-zero cooling needs

4. Robust Industrial Design

• Built for continuous heavy-duty operation

• Made with stainless steel or carbon steel components for durability

5. Reciprocating or Screw Compressors

• Available in different configurations depending on cooling load:

  • Reciprocating for small to medium loads

  • Screw compressors for high-capacity continuous cooling

6. Plate or Shell & Tube Heat Exchangers

• Uses plate-type or shell-and-tube evaporators and condensers for efficient heat transfer

• Often includes a separate water/brine circuit

7. Automatic Controls & Safety Systems

• Includes:

  • Pressure and temperature sensors

  • Ammonia leak detectors

  • Emergency shutdown systems

  • PLC or SCADA-based automation for precise control

8. Environmentally Friendly

• Ammonia is a natural, eco-friendly refrigerant with no global warming effect

• Helps companies meet green regulations and sustainability goals

9. Application Versatility

• Suitable for:

  • Dairy and beverage industries

  • Breweries

  • Food processing

  • Ice-making plants

  • HVAC systems in large commercial buildings
