The flat plates and the corrugated plates form chnnels for fresh or exhaust air stream. When the two air streams passing through the exchanger crossly with temperature difference, the energy is recovered.

Paper recuperator

* Made by HOLTOP 3rd generation E.R paper

* Structured with flat plates and corrugated plates

* Two air streams flow crossly.

*  Suitable for room ventilation system and industrial ventilation system

* Heat recovery efficiency up to 80%

Paper recuperator is made of ER paper which is featured by high moisture permeability,  good air tightness, excellent tear resistance,  and aging resistance. The clearance between the fibers is very small, so only the moisture molucules of small diameter can go through, the odor molecules of larger diameter are unable to pass through it. By this means, the temperature and humidity can be recovered smoothly, and prevent the pollutants infiltrating to the fresh air.

Installed in air handling units

Paper recuperator can be used in the air handling unit (AHU) as a main part of the heat recovery section, and the bypass can be built in when required. 

Installed in ducts

Paper recuperator can also be installed in the ducts of ventilation system as a main part of the heat recovery section. The installation is very flexible. 

Installed in air cooler for wind turbin nacelle, and other waste heat recovery fields.
