Specification text

Hoval Enventus 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.

Constructions

  • -: Single-plate heat exchanger (standard)
  • Z: Twin-plate heat exchanger – 2 single-plate heat exchangers, optionally without bypass, with bypass or with bypass and dampers. If dampers are ordered, they are only mounted on one of the two exchangers. Assembled on-site in the air handling unit.
  • Y: Twin-plate heat exchanger – 2 single-plate heat exchangers with bypass and dampers on both exchangers. Assembled on-site in the air handling unit.

Options

  • Side or middle bypass: coordinated with the exchanger package.
  • Control dampers: installed in front of exchanger package and bypass; sheet-steel damper blades, Aluzinc sheet-steel casing; high-quality plastic drive gears outside the air flow; leak-tightness class 2 according to EN 1751; series G and C are powder-coated.
  • Side or middle recirculation bypass: coordinated with exchanger package; incl. control dampers and recirculation damper with sheet-steel damper blades, Aluzinc sheet-steel casing and high-quality plastic drive gears outside the air flow; leak-tightness class 2 according to EN 1751; series G and C are powder-coated.
  • Leak-tightness test: additional sealing with casting resin; extremely watertight design as a result; incl. water test.
  • Horizontal installation: plates arranged horizontally.
  • Adapter for actuator: for inside drive of the control and recirculation dampers.
  • Reinforced packaging: additional wooden crate on top, exchanger package with covered on 4 sides with wood-fibre boards, machine wrapping film.
  • Block of 4 delivered loose: exchanger sizes made up of 4 packages, delivered loose, assembly on-site.
