Compact heat exchanger integrated into air duct system.

A Japanese electronics company has developed a new type of gas-to-gas heat exchanger, called the Ductron. The heat exchanger has a simple structure composed of aluminium or stainless steel pass partition plates stacked with a gas passage (1 cm wide) between each plate, Heat exchange duct- Ductron and can be installed as part of an air duct system. It is applicable not only to HVAC systems but also to various industrial applications. The efficiency level is over 5 0%. The payback period is very short (in some cases less than one year) owing to low initial costs and almost zero extra maintenance and running costs.
