Crossflow heat exchangers

Proven technology, low maintenance

Our crossflow heat exchangers are the optimal solution for ventilation systems with high air flows.

M-ERV enthalpy exchangers

Our M-ERV crossflow enthalpy exchangers feature our latest membrane and heat exchanger technology. They offer even higher latent efficiency and lower pressure drop than previous generations.


  • Lower supply air pressure drop
  • More robust frame structure
  • Lower freezing limits (-10 °C to -15 °C) and shorter thawing time

X-ERV enthalpy exchangers

Because they have non-moving parts, our X-ERV crossflow enthalpy exchangers are the perfect solution for applications requiring low maintenance. Thanks to their polymer barrier layer, they reliably block pathogens, odors and pollutants during heat and moisture exchange.


  • High transfer capacity for greater comfort 
  • Long product life with excellent transfer values
  • Low overall weight

CORE Multicore for large systems

For ventilation systems with volume flows greater than 11,900 m3/h, we offer our multicore configuration, which reduces the pressure drop in the crossflow heat exchanger. The configuration combines up to four units that are pre-assembled for delivery.


  • Four crossflow heat exchangers in one unit
  • Reduced pressure drop
  • Plate sizes up to 157 cm

Optimal technology for high air flows

New regulations require ventilation with high efficiency and lower pressure drop. The more compact counterflow principle is ideal for many heat and enthalpy exchanger applications. But for large air flow capacities, such as in commercial applications, crossflow heat exchangers can be a cost-effective alternative.

Outstanding efficiency

Under the Ecodesign Directive ErP 2009/125/EC, ventilation system manufacturers in the EU must meet minimum requirements for energy efficiency. Counterflow heat exchangers are a proven solution. However, especially in applications with high volume flows and a lower pressure drop, crossflow heat exchangers are a cost-effective alternative. This requires a highly sensitive and latent transfer capacity with a moisture exchange that blocks the transfer of contaminants.

Excellent price-performance ratio

Our crossflow heat exchangers meet all the requirements to deliver an optimum price/performance ratio for your ventilation systems, making them the ideal solution for energy recovery in applications with high volume flows. Our patented polymer membrane ensures the efficient exchange of air. And with no moving parts, maintenance is reduced to a minimum.
