Application
Example
5.7.4 Proprietary Developed HEP Element
The heat exchanger element uses a High Efficiency Paper (HEP) that has superior moisture-absorption
and humidifying properties and doubles the current efficiency of moisture absorption. The heat exchanger
unit speedily recovers heat contained as latent heat (vapor). The element is made of a material with
superior flame-resistant properties and is treated with an anti-molding agent.

Features
•
High air shielding
Even in the conventional less humidity conditions, maintaining the features of the material that can get
excellent moisture permeability, we have achieved high air shielding, by special processing in the step of
milling paper.

Supply Fresh-up
(Excessive outdoor air supply)
Supply air volume can be set at a higher level
than the exhaust air by the remote controller.
•
Prevents inflow of toilet odor
•
Prevents inflow of outdoor air in winter

Moisture absorbing liquid
Polymer material that inhibits air permeability that treated on the surface of the heat exchanger
element restrains air permeability.
(Excessive exhaust air supply)
Exhaust air volume can be set at a higher level
than the supply air by the remote controller.
