Adiabatic Cooler
Adiabatic Coolers — Efficient, Sustainable, Versatile
Adiabatic cooling combines dry cooler technology with a pre-cooling mist system. Water is sprayed or evaporated over special pads in front of the coils, reducing the incoming air temperature before it passes through the heat exchanger—resulting in higher cooling efficiency, especially during peak summer heat.
WORKING PRINCIPLE
In the adiabatic cooling process, hot ambient air first passes through specially designed adiabatic pads, where water is sprayed from an external source. As the air moves through these wetted pads, the evaporative cooling effect lowers its temperature before it reaches the coils. To ensure efficiency, a PLC-based control system automatically regulates the amount of water sprayed, using only what is necessary. This intelligent adjustment maintains stable cooling performance even during peak ambient conditions. Additionally, the anti-scaling design of the pads prevents water drift, protecting the heat exchanger from scaling and ensuring long-term reliable operation.
Applications of adiabatic Coolers
Engine & Equipment Cooling
- Engine & Equipment Cooling
- Mobile/remote sites prefer adiabatic coolers due to low maintenance and no permanent water requirement.
Industrial Process Cooling
- Cooling of process fluids (glycol, water, oil, etc.) in industries like chemical, petrochemical, steel, plastic, glass, and cement.
- Used for maintaining stable temperatures in heat exchangers, reactors, compressors, and hydraulic systems.
Power Generation
- Cooling for diesel/gas engines, turbines, and generators.
- Common in backup power plants, data centers, and cogeneration (CHP) systems.
HVAC & Data Centers
- Used in large air-conditioning systems, chilled water plants, and IT data centers where reliable heat rejection is needed without heavy water consumption like cooling towers.
- Maintains low water usage and avoids Legionella risks.
Food & Beverage Industry
- Process cooling in breweries, dairies, bottling plants, and cold storage warehouses.
- Ensures stable cooling without contamination risks.
Plastic & Mould Cooling
- Used in injection molding, extrusion, and blow molding machines for precise temperature control.
- Replaces traditional cooling towers to reduce water consumption.
Environmental & Energy Saving Applications
- Adiabatic coolers are widely used in areas with hot, dry climates where dry coolers alone are insufficient.
- They combine dry cooling efficiency with evaporative assistance to reduce energy use.
