Evaporative Condenser

Thermax Evaporative Condenser operates in a manner wherein a condenser is integrated into a cooling tower which rejects the latent heat of condensation of refrigerant (Ammonia/Freon) through a coil to the surroundings by means of evaporation. Water sprayed onto the coil exchanges heat with the refrigerant.
A small quantity of water is evaporated into the air thereby cooling the remaining water cascading to the basin at the bottom. Post evaporation the saturated air passes through the drift eliminators and then forced out using a fan.
The coil serves to isolate the process fluid from the outside air, keeping it clean and contamination free in a closed loop, thus creating two separate circuits.

• Primary / Internal circuit in which the process fluid / gas circulates inside the coil
• Secondary / External circuit where water is sprayed over the coil and mixes with outside air
• Systems using a Thermax Evaporative Condenser are far simpler when compared with conventional system. The Primary circuit is identical to the conventional system whereas the cooling tower, secondary pumps, PHE / shell & tube heat exchanger and associated piping, valves are eliminated. Thermax Evaporative Condenser has a built in heat exchanger coil, spray pump & exhaust fan, which saves power & installation space while ensuring ease of maintenance.

  Operating Principle
  • The refrigerant flows through the coil of the evaporative condenser.
  • Heat from the refrigerant is rejected through the coil tubes.
  • Part of the heat is removed directly by the downward induced air and discharged to the surrounding.
  • Rest of the heat is rejected to the water cascading down over the tubes.
  • Simultaneously, air is drawn in through the air inlet louvers at the base of the evaporative condenser.
  • A small portion of the water is evaporated which removes the heat. The warm saturated air travels through the drift eliminator & discharged by the fan to the surrounding, thereby reducing drift water loss.
  • Post heat exchange, the condensed refrigerant flows to receiver tank
