Counterflow evaporative condenser

Operating principle

The counterflow evaporative condenser uses water and air to exchange heat with hot refrigerant gas inside a coil, condensing it to liquid. It contains a spray system, condensing coil and drift eliminator, with an external circulating pump, axial fan and optional electronic scale-control device. Refrigerant enters at the top of the coil and leaves as liquid at the bottom. Water spreads over the coil while induced airflow carries away heat and evaporated water. Unevaporated water returns to the sump for recirculation; a float valve replenishes water losses.

Features

• Efficient heat exchange

  Closely arranged elliptical coils reduce airflow resistance. Axial fan airflow supports heat exchange while helping prevent dry spots and scale formation on coil surfaces.

• 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

  Counterflow air and water support effective heat exchange at a low condensing temperature, with reduced water and power consumption, low noise and low maintenance costs.
