here is the difference
The idea to bring ventilation systems right to the work space was at the beginning of the devellopment of our heat exchangers and air units. So there were not just technical problems to solve, we also had to think in architectual and esthetical ways.
The heat exchanger as and founding on these also work in a counter current way. This way is supperior to the mainly used cross flow principle because of the higehr ability of heat recovery. Just like this a heat recovery of more then 80 % can be achieved.
Nowadays it is indispensable to think in a global way. For product devellopement does that mean to think of its end right from the beginning. There are economical and ecological reasons for creating this product so its end should not cause any problems.
The core of the heat exchanger is entirely made of high density polyetylene. PE-HD is a plastic that is used in the food industry as well. It's known from packaging like for example the tupperware box. Its production is energetically much better then aluminum that is used in most heat exchangers. The is also used less energy to recycle that material.
The air units are equipped with EC-engines. They have a very good efficiency and a low noise level.
Founding on these components arise ventilation systems for different pretentions.
Rooms with an airing need of up to 480 m³/h can be ventilated with air units. They are available in three different sizes for 120, 240 and 480 m³/h. Heat exchanger, ventilators, filter and silencers are combined to a compact unit.
Higher air needs can be pleased with heat exchangers like the one shown above. The shell of the displayed heat exchanger is made of translucent polypropylene. They are available in three sizes as well, 120, 240 und 480 m³/h. They are integrated alone or as a package of several combined heat exchangers into the free hanging ventilation system. At first the viewer will notice the translucent and lighted shell and with second view he will notice the efficient technology. The shell can be delivered as in different colors. There is also the possibility of a custom made cover from a different material.
