The REC Temovex Blue 4 is the third generation of the Temovex units. It is a compact unit for effective ventilation with efficient heat-recovery. The appliance has, like its predecessors, a white goods design and is intended to be placed on the floor in utility rooms, boiler rooms, auxiliary kitchens, hallways, etc. The unit consists of two ultra-efficient DC fans, easily accessible filters, heater (electrical or hot water) and automatic bypass. Extremely large double counterflow heat exchanger allows over 90% of the heat energy from the extract air to be recovered and used to heat the fresh incoming air. By using a counter-flow heat ex-changer there is no air leakage between extract air and fresh air. The Blue 4 is a totally redesigned unit, currently undergoing testing to be certified by the Passive House Institute in Germany.

How a ventilation and heat recovery system works
The principle for a ventilation-heat recovery system with supply and extract air is simple. Harmful contaminants and moisture held in the interior air is removed via the extraction vents in the “dirty rooms”; kitchen, bath, toilets and utility rooms. Before leaving the house, the old air gives off its heat to the fresh incoming air in the heat-exchange unit.
With a balanced mechanical system, you control the amount of ventilation in the house. Not too much on windy and cold days and enough on humid and mild days. At the same time the incoming air is filtered from dust and pollen. The system allows you to determine where you want the fresh air to be introduced, in what quantities and at what temperature. The fresh new air is normally supplied through a vent in the ceiling in the “clean rooms” such as bedrooms and living rooms.
A whole house ventilation system helps to provide consistent temperatures though-out the house or apartment. The house or apartment must be reasonably well insulated and draft-proofed for the system to work to its highest potential. The used air, which has now released most of its energy content, is fed out through the exhaust duct (brown duct). This happens most commonly though either a louvered grille or combi-box on an external wall, or through a roof hood.
Ventilation units make your home into a thermos! You retain the heat in the building without the need for unnecessary new thermal energy. As a result your heating system will have a much easier job to do. The kitchen extraction fan is usually kept separate to avoid contamination of the ducts and of the main unit.
