Internal Installation Options

Internal, suspended coolers

Evaporative coolers can be installed internally within a building where there is already adequate existing ventilation. The flow rate of the ventilation must exceed the flow-rate of the internal cooler, otherwise you will end-up re-circulating air.

The stainless steel plenum chamber which distributes air into the room is delivered with the louvres closed.

These are then opened once the cooler is being commissioned to direct the air in exactly the desired way.

In this way air can be directed to exactly where it will have the most effect and you can achieve either total coverage of a room, or you can direct the cold air down specific "corridors".

This is especially useful, for example where machinery (e.g. Computers) sit in banks and develop considerable heat (which rises). Cold air can be distributed cleanly between such heat sources to give the maximum cooling effect and without the cold air becoming pre-mixed with the warm air rising from the machinery.

Using a Brominator

In many cases, internal air being recirculated becomes contaminated (or the external source of air may be). This requries the use of a brominator to sterilise the air. This unit supplies a constant flow of 0.5ppm Bromine to prevent any bio-films developing (and is the air-cooling equivalent of chlorinating a swimming pool).

A single brominator can support up to 10 eco coolers. Bromine levels are maintained (like in a pool) by topping up on Bromine tablets. However, where used, the waste water must be directed to a foul drain (such as a sewer) and not to a clear-water drain.

Example Installation method

In this example, in a printing works, the cooler "G" is internally mounted and air is extracted via extraction fan "H". Fresh air is supplied from outside via an inlet fan "I". Note in this instance that toal ventilation must exceed the flow rate of the cooler unitor you risk recirculating and fouling the air.
