Introducing the HU-EX6 172 by ZERN ENGINEERING - the world's only plate heat exchanger of this size available in a full polystyrene (PS) housing.

The product's compact dimensions, optimised geometry, and market-exclusive casing solution for next-generation ventilation systems are key features.

The ZERN HU-EX6 172 has been designed for decentralised units and compact air handling units (AHUs). It delivers high performance in a small footprint, without compromising efficiency or durability.

• Dimensions: width — 397 mm, height — 172 mm, depth: 100–600 mm
• Airflow capacity: ideal for small and mid-range residential ventilation
• Thermal efficiency: up to 90%
• Casing: polystyrene (PS) or metal options
• Core: high-quality polystyrene plates with refined internal geometry

Why does HU-EX6 172 stand out?

1. The only exchanger of its class on the market with a PS housing
2. Lightweight, corrosion-resistant, moisture-resistant construction
3. Optimized plate geometry for maximum heat recovery in a compact body
4. Table efficiency and balanced pressure drop across operating ranges
5. Perfect fit for decentralized and space-restricted ventilation systems

With HU-EX6 172, compact no longer means limited. It’s an innovative solution for manufacturers seeking performance, durability, and design flexibility - all in one unique package.
