Hoval crossflow plate heat exchanger for energy recovery, consisting of exchanger package and casing. The exchanger package consists of specially formed aluminium plates. The surface profile has been optimised through extensive testing. The focus was on performance: Krivan plate exchangers offer an ideal ratio between thermal efficiency and pressure drop. The plates are connected by an interlocking fold, which means that the material is several times thicker at air entry and exit. The corners of the exchanger package are sealed into particularly rigid aluminium extrusions in the casing with a sealing compound. The side walls of Aluzinc sheet steel are bolted tightly to these extrusions. All performance data is certified by Eurovent and TÜV Süd. The suitability of the exchangers for use both in general ventilation technology and in hospitals is certified by independent test institutes.
