Hoval Krivan – now from 100.000 m³/h

Hoval is expanding its successful Krivan with a solution of 4 units as a block with air flow rates up to 100 000 m³/h.

The same applies to all Krivan units:

  • up to 20% higher air flow rate

  • ErP-compliant

  • supreme differential pressure stability up to 2500 Pa

  • simple design with plug and play

« Finally, the successful Krivan can also be used in ErP-compliant systems with high air outputs. »

Krivan - advantages

Up to 20% higher volume flow

With the Krivan you can immediately build better products. At the same size you get 20% higher volume flow than with the S-design. You can therefore design your systems much smaller and more cost-effectively.



The Krivan was developed specifically to meet the requirements of the ErP Directive. All versions and sizes are compatible for use with air handling units meeting the requirements of Ecodesign 1253/2004 without any changes to their design and construction.


Supreme stability.

The new design lends the Krivan levels of stability that have never been seen before. Tests carried out by the TÜV SÜD identified a minimum increase in pressure drop (approx. 4% at 1000 Pa).


Simple design with plug and play

It goes without saying that the Krivan is available in a ready-to-install format complete with all attachment parts.

The Krivan has a crucial design advantage: with the same dimensions as the tried-and-tested S heat exchanger, it can easily replace or supplement this heat exchanger in existing constructions.


Why Krivan?

« Higher volume flow helps you to immediately build better products. »


«You have the choice: more power, smaller heat exchanger or saving energy.»


« Krivan is designed to easily fit in with your production. »
