Total heat exchanger 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 molecules 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.

Main Feature:

Heat recovery efficiency up to 85%
Enthalpy efficiency up to 76%
Effective air exchange rate over 98%
Selective molecule permeability
Flame retardant and mildew resistance

Working principle

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

Performance index

E.R. paper performance introduction

Heat exchange paper: for heat and moisture exchange, the main performance standards are diathermancy, moisturepenetrability and air permeability.

Corrugated paper: to construct the frame for the heat exchanger, flowing passages of the air stream.

Anti-bacteria and mold prevent performance

The bacteria exists in the damp air, when air goes through the heat exchanger, bacteria may stick on the walls of the
exchanger. If the heat exchanger doesn't have the anti-bacteria ability, it will grow on the inside wall, and then
blown into indoor, which will cause indoor air pollution. That is why the anti-bacteria performance is required. The
ability of bacterial growth inhibition and killing bacteria, to prevent the production of mold, is an important factor of
heat exchanger paper.
By adding the bactericides to the surface of paper and the anti-bacteria agents to the slurry, the heat exchanger has
abilities to kill bacteria (such as Escherichia coli and staphylococcus) and inhibit fungal (such as Candida albicans)
and prevent the bacteria and germ spreading in the air. Holtop heat exchanger paper was tested by Guangzhou Industry Microbe Test Center, and shown the antibacterial effect, and its mildew grade is 0.

Product Specification 

The heat exchange paper and corrugated paper are adhesived with waterborne binder, the core and cover are sealed with special sealant to total separate the supply air and exhaust air, in order to keep the structure strength and air tightness and prevent the cross contamination. It is widely applied and the maximum temperature should not exceed 100 C.
For size A within 500mm and the size L within 600mm, the heat exchanger is built in one module. For size A bigger
than 500mm and size L bigger than 600mm, the heat exchanger is built in multi-modules.
