Counterflow Heat Exchanger CN
Counterflow heat exchanger CN operates on a simple and efficient principle. Inside the exchanger core, the air streams move in opposite directions along parallel aluminum plates. As a result, this design provides higher temperature efficiency than a crossflow heat exchanger core.
Two adjacent aluminum plates create separate channels for fresh air and exhaust air. Heat transfer occurs while the streams move partly in crossflow and partly in counterflow. Therefore, the fresh and exhaust air streams remain completely separated.
High Efficiency
Heat recovery of up to 90% helps improve system performance while reducing overall energy demand.
Hygienic Air Separation
Fresh air and exhaust air remain fully separated. Therefore, the design prevents air mixing and supports safer indoor air quality.
Long Service Life
The robust aluminum plate construction contains no moving parts. As a result, it provides reliable and long-term operation.
What Is a Counterflow Heat Exchanger CN?
Counterflow plate heat exchangers are designed for energy recovery. Therefore, they help reduce energy consumption while delivering high performance in heat recovery ventilation systems.
These units can be used in residential, commercial and public buildings. In addition, they are suitable for energy-efficient building systems designed in accordance with European Union and Ecodesign requirements.
