Zern 200/140 Cross-Flow Heat Exchanger – Polystyrene
The Hp-EX4 200 is a highly efficient polystyrene heat exchanger designed to save and reuse thermal energy from air flows, significantly improving system efficiency.

Supply and extract air flows are separated by the heat exchanger plate walls, preventing the transfer of contaminants, dust, moisture, or other unwanted substances between flows.

• Heat transfer efficiency: up to 80%

• Plate material: polystyrene, providing maximum heat transfer compared to similar aluminium plates

• Standard air flow: 50 m³/h

• Temperature (IN): 18–25 °C | (OUT): 20.23–22.77 °C

• Relative humidity (IN): 37–75 % | (OUT): 48.82–55.18 %

• Face air velocity: 0.49–0.50 m/s

• Air pressure drop: 21.61–22.27 Pa

• Thermal efficiency: 68.07 %

• Heat recovery: 0.08 kW

• Condensation: 0 kg/h

The unique plate design and stacking arrangement ensure high thermal efficiency and reliable operation in residential, commercial, and light industrial applications.
