In our previous posts, we looked at the main types of plate heat exchangers.
Today, let's explore the cross-flow heat exchangers from ZERN ENGINEERING.
HP Series - high-efficiency sensible cross-flow plate heat exchangers. Designed for balanced ventilation systems where reducing energy consumption is paramount, these exchangers redefine efficiency.
Thanks to cross-flow, fresh supply air flows perpendicularly to the exhaust air, ensuring efficient heat exchange. This process, made possible by the innovative plate configuration and improved airflow dynamics, helps to maintain an optimal temperature balance in the room. Parallel airflow across the plates maximizes surface contact, promoting efficient heat exchange and minimizing energy loss. The result is constant comfort and energy-efficient air exchange throughout the room.
The Hp series is flexible in application, whether in a monobloc configuration for compact installations or in a combi version for the most demanding high airflow scenarios.
Enhance your ventilation system with ZERN ENGINEERING's Hp Series heat exchangers.

Sensible cross-flow heat exchangers by ZERN ENGINEERING (Hp-EX4 series) are compact plate cores for temperature-only recovery. The Hp-EX4 series uses stacked polystyrene plates to deliver high sensible effectiveness with low pressure drop - ideal for decentralized units and compact AHU modules where humidity transfer is not required.
Key operational parameters
Performance сharacteristics
Thermal efficiency
Up to 75% under optimal conditions
Pressure drop
Typically, 40–150 Pa (depends on air flow, plate spacing & core size)
Operating temperature
−25 °C to +50 °C
Air leakage
<1%
Maintenance
Durable, corrosion-free PS core; washable for long service life
Technical features
Design and structure
3D model
Principle of operations
Two sealed airstreams pass perpendicularly (90°) through separate PS plate channels. Heat crosses the thin walls without air or moisture mixing, providing stable, effective recovery and preventing odor or particle carryover.
Core material
High-quality thermoformed polystyrene plates stacked into fully isolated channels; corrosion-free, hygienic, and washable.
Casing materials
Polystyrene (HIPS) - lightweight, insulated; ideal for compact residential units.
Main areas of use
Applications
- Residential ventilation - apartments, small homes, room units.
- Small commercial - shops, offices, classrooms.
- Dehumidifiers & dryers - controlled air drying with zero moisture carryover.
- Decentralized systems - compact, zone-based HRV units.
SIZES OF OUR HEAT EXCHANGERS
MODEL LINE
- Dimensions A and B are fixed. Dimension C is the width of the heat exchanger and can be varied.
- Each heat exchanger model can be manufactured with a depth (dimension C) ranging from 100 mm to 800 mm per unit.
- Heat exchangers with a width of 800 mm and above are supplied as two or more units.
