Parallel-flow evaporative condenser
Coils and a fill section provide heat exchange with parallel water and airflow.
Discuss this product ↗Product overview
Operating principle
The parallel-flow evaporative condenser uses water and air to exchange heat with hot refrigerant gas inside a coil. It includes a spray system, condensing coil, fill heat-exchange layer and drift eliminator, with an external circulating pump, axial fan and optional electronic scale-control device. Refrigerant enters at the coil top and leaves as condensed liquid below. Spray water and air absorb heat; a portion of the water evaporates and is carried away by the fan. Remaining water returns to the sump, and a float valve replenishes water losses.
Features
-
Efficient heat exchange
Closely arranged elliptical coils reduce air resistance. A fill section provides secondary heat exchange with parallel water and airflow, helping prevent dry spots and scaling while improving heat transfer.
-
Convenient transport
A split construction simplifies transport and installation.
-
Easy maintenance
Large access doors, service passages and fixed ladders facilitate maintenance. A sump float valve and stainless steel filter support servicing without shutting down the unit.
-
Low running costs and efficient operation
Parallel water and airflow support efficient heat exchange, a low condensing temperature, reduced water and electricity consumption, low noise and low maintenance costs.
