Fully Packaged Range of Dry Air Coolers

Industry relies on water to cool much of its reduction machinery.  The cooling of this essential resource can be achieved in a number of ways:-

Using water…

  • straight off the mains

  • via evaporative cooling towers

  • through dry air coolers

  • via a refrigeration system

  • via existing ring main of cool water

The Equipment
There are 12 models in our range of dry air coolers with duties ranging from 1kW to 200kW, all fully packaged so as to minimise on-site works, just connect flow and return into factory ring main, fill tank, connect electrical supply and equipment is ready to start work.
Cooling Capacity
The cooling capacity of the dry air coolers is based on cooling water through 10°C so that it is returned to the process 10°C above ambient temperatures i.e., in an ambient of 20°C water will be cooled from 40°C to 30°C. The heat extraction rate will vary according to the differential between the inlet and ambient temperature. The greater this differential the greater the heat extraction rate of the cooler.
