Overview
The ERA cross flow air to air heat exchanger is made of antiseptic hydrophilic aluminium foil, which have no
secondary sollution, thermal conductivity fast, and high heat transfer rate features.




Concave&convex foil Five layer curring 45°angle 90°angle
Working principle
The air to air heat exchanger is the major part of heat recovery ventilator. Because the different temperature
between the fresh air and exhaust air, the air is forced to crossover through the heat exchanger, the heat would
transfer from the hotter side to the colder side, so as to recover the energy from exhaust air.Two airstream never
come into direct contact, make sure no cross contamination.
Cross flow
Feature
1. Adopt antiseptic hydrophilic aluminium, resistant to corrosion, with long service life.
2. Module structure, no use of rivets or screws.
3. No running components, low maintenance cost.
4. Suitable for washing with water or neutral detergent.
5. Extremly high strength and pressure related stability.
6. Compact structure, small volume, suitable for various occasions.
Production technology
1. The surface of air to air heat exchanger was processed with heat transfer enhancement techniques,increased
the 10% heat transfer area.
2.Convex and concave air channel, ensure the strength and tightness of heat exchanger, could bear high pressure.
3.Cross air channel, double folding process of the face side edges, which is equal to 5 times material thickness,
ensure the high intensity and tightness.
4. All joints are airproofed by airproof glue, ensured that the heat exchanger has excellent air tightness.
Model Range

On request ≤650 | On request ≤1000 | On request (45°/90°) | 2.0-8.0 |
Remark:
1. As soon as possible to use economic face velocity (1-m/s ~ 2.5 m/s) air to air heat exchanger, ensure
the economic running.
2. The sectional size, height and plate distance are available to customers′ requirements.
Applied range
The air to air heat exchanger is the major part of heat recovery ventilator(HRV), for air volumes up
to 30,000 m3/h, include the household and commercial ventilations. The heat exchanger controlled
the ventilation, recover the heat energy in winter and cold energy in summer, not only save the energy
but also give room for fresh air.
