Crossflow heat exchangers

Proven technology, low maintenance

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

ERV-M-Series.
ERV M-Series enthalpy exchangers

M-Series enthalpy plate exchangers utilize a patented polymer membrane to transfer both sensible and latent energy while maintaining separation between air streams. The M-Series delivers reliable energy recovery performance with low pressure drop.


  • Patented polymer membrane technology
  • Blocks odours and VOCs between air streams
  • Available in residential and commercial sizes
  • 5 years warranty
  • AHRI Certified
  • UL 723 & UL 1995 compliant

ERV-X-Series.
ERV X-Series enthalpy exchangers

X-Series enthalpy plate exchangers are designed for flexible integration into HVAC systems requiring custom dimensions and performance characteristics. The X-Series offers customizable plate sizes, plate spacing, and configurations to meet specific application requirements.


  • Plate spacing configurable in 1 mm increments
  • Supports pressure differentials up to 6 in.w.c.
  • 5 years warranty
  • AHRI Certified
  • UL 723 & UL 1995 compliant

ERV-M-and-X-Series.
ERV Multicore: M-Series and X-Series

Multi-CORE assemblies combine up to four M-Series or X-Series exchangers into a single factory-assembled module. Available in standard or custom configurations, Multi-CORE solutions provide scalable energy recovery for large commercial HVAC applications.


  • Factory-assembled modules
  • Built using M-Series or X-Series platforms
  • Available in standard and custom configurations
  • Plate sizes up to 2 m (78.7 in.)
  • 5 years warranty
  • AHRI Certified
  • UL 723 & UL 1995 compliant

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.
