The Heat Exchanger

The heart of every Delta Cooling System Ltd Ventilation system is the heat exchanger. This is where the heat from the outgoing air is transferred to the incoming air. This works both ways so if the outside temperature is higher than inside the exchanger helps to maintain a constant pleasant internal climate.

The unique patented Delta Cooling System Ltd counter flow heat exchanger design has proven itself to be one of the most efficient on the market. Combined with a surface area of 60m² in the family house size units provides exceptional heat recovery of up to 99% (thermos 200 dc 97- 99% at 200m³ /h).

Designed to be Inaudible

The high quality balanced fans and attention to detail make Delta Cooling System Ltd units the quietest on the market. There is no point in building a low energy house if people don’t want to live in it. Experience has shown that when constant, even low noise levels prove to be disturbing. Combine Delta quality with the very best ducting design drawing on years of experience in Kenya.

Air Quality

Delta Cooling System Ltd  uses high quality large surface area filters that ensure a clean air supply. The large surface area of the filters provides an extended service interval and reduces loss of flow. A properly tuned comfort ventilation system prevents CO2 build up with out the need to open windows. Removing the need to open windows has the added benefit of keeping the noise of contemporary life out side the home.

Product Range

Delta Cooling System Ltd units can be fitted in suspended ceilings, horizontally in boxing over kitchen cupboards, vertically in a larder unit, or a utility room or garage. They can supply ventilation demands from 30 to 6000m³/h. The compact units utilise air source heat pump technology to provide both heat and hot water along side the ventilation requirement.
