How they work
Warm water from the heat source is pumped to the water distribution system at the top of the tower. The water is distributed over the fill (heat transfer media) by means of large orifice nozzles. Simultaneously, air is drawn in through the air inlet louvers at the base of the tower and travels upward through the fill in the opposite direction of the water flow.
A small portion of the water is evaporated which removes heat from the remaining water. The warm moist air is drawn to the top of the cooling tower by the fan and discharged to the atmosphere. The cooled water collects in the basin at the bottom of the tower and is returned to the heat source. The vertical air discharge and the distance between the discharge air and fresh air intakes reduces the chance of air recirculation, since the warm humid air is directed up and away from the unit.
Construction Materials
Packaged cooling towers are manufactured from fibreglass panels and in some cases also available in steel and stainless steel construction. Internal components are selected to offer long life and ease of maintenance.
Site-Erected cooling towers are available in a wide range of materials from FRP, steel, stainless steel and concrete.
Spare Parts & Servicing
Spares and accessories are available for all Evapco cooling towers, along with retrofit spares and accessories for most other makes of cooling tower.
We offer a full range of aftermarket servicing for all Evapco cooling towers.
Applications
- Heat rejection from water cooled chillers
- Heat rejection from industrial heat sources, such as generators, compressors
- Reducing heat from milk dryers, prior to releasing waste product into the ground, heat must not be added the ground, as will upset the echo system
- Heat reduction of data sites
- Cooling of cooked food products, extending the life if cooled quickly, many producers cool the product in large water vats
- Cooling of water used in boring machines and other machining equipment
