Spray Water Type Air Washer
Efficient Adiabatic Cooling & Humidification Systems
Spray Water Type Air Washer
Air washer units in which spray water is used as medium for adiabatic cooling of air in humidification systems (by direct evaporation of water into the air stream thereby reducing the air dry bulb temperature and raising its humidity). These systems provide efficient air conditioning through evaporative cooling principles.
Adiabatic Cooling Technology
Spray water type air washers utilize the principle of adiabatic cooling where water evaporates into the air stream, absorbing latent heat and reducing dry bulb temperature while increasing humidity. This energy-efficient process provides natural cooling without mechanical refrigeration.
Design & Working Principle
Spray Water Evaporation System
The air washer unit consists of a spray chamber where finely atomized water is introduced into the air stream. As water evaporates, it absorbs heat from the air, reducing dry bulb temperature while increasing moisture content. This adiabatic process provides effective cooling and humidification simultaneously.

Engineering Features
Adiabatic Cooling Process
Direct evaporation of spray water into air stream reduces dry bulb temperature through latent heat absorption. This natural cooling method requires significantly less energy compared to mechanical refrigeration systems.
Precise Humidity Control
Spray water systems provide accurate humidity control by regulating water flow and temperature. Ideal for applications requiring specific humidity levels such as textile mills, printing facilities, and clean rooms.
Air Washing & Cleaning
Water spray effectively captures dust, pollen, and airborne contaminants. The air washing action removes particulates, gases, and odors, providing cleaner and healthier indoor air quality.
Energy Efficient Operation
Consumes up to 70% less energy than conventional air conditioning systems. Uses water as the cooling medium instead of chemical refrigerants, making it environmentally friendly.

Working Principle
Adiabatic Cooling Process
The spray water type air washer operates on the principle of adiabatic saturation. As air passes through the spray chamber, finely atomized water evaporates into the air stream. This evaporation process absorbs latent heat from the air, reducing its dry bulb temperature while increasing its moisture content. The process continues until the air approaches saturation conditions.
