6.8.7.4 Proprietary Developed HEP Element
The heat exchange 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 exchange 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.
• Polymer material that inhibits air permeability that treated on the surface of the heat exchanger element restrains
air permeability.
