Working Principles

The cooling gas is re-circulated through the coil. Meanwhile the secondary circuit water is sprayed over the tubes. At the same time, the fan induces an airflow through the coil evaporating a small part of water. This evaporation is owed to the heat obtained from the gas in the heat exchanger, thereby cooling and condensing the gas itself.

EWK evaporative condensers are characterised by their excellent coil performances and by their long-lasting polyester corrosion-proof casing. These condensers have a low energy consumption due to the efficient aerodynamic design of the top casing and to the vast quantity of airflow. EWK evaporative condensers are also extremely easy to maintain.

In addition to this, evaporative condensers can be easily removed, dismantled and re-galvanised in unfavorable ambient or water hardness conditions.
