Hoval presents cross-flow plate heat exchangers with dry heat recovery efficiencies of more than 80 %

High-efficiency heat recovery is a major requirement today. The counterflow heat exchangers currently available on the market achieve extremely high heat recovery efficiencies, but they are expensive and complex to handle. Based on expertise gathered over more than 40 years, Hoval has developed a new plate surface and thus manufactures the most efficient cross-flow heat exchangers in the world.

Heat exchangers with this new plate surface achieve dry heat recovery efficiencies of 80 % and more even in cross-flow. Of course, the precise values depend on the heat exchanger size and the volume flows; they can be calculated quickly and easily with the design software Hoval CAPS. Hoval CAPS is certified by Eurovent and TÜV (German technical inspection agency) and is available for free download on the Internet (wrg.hoval.com). 

The advantage of the new high-capacity heat exchangers as against counterflow exchangers with comparable heat recovery efficiencies is obvious: Due to their compact, cube-shaped design, they save space and thus costs for the air handling unit. Bypasses and dampers can be ordered together with the heat exchanger and pre-assembled; Hoval delivers the entire system ready for installation. An additional bonus: Hoval heat exchangers are also available with a recirculation bypass, which means that no separate recirculation damper is required in the air handling unit.

Hoval heat exchangers with the new plate surface achieve outstanding heat recovery efficiencies – Example: The heat recovery efficiency of a heat exchanger of type SV-85/A is 81 % with a pressure drop of only approx. 50 Pa.
