Introduction de produit

The air-to-air plate heat recovery unit combines a formed aluminum plate core, four duct connections and separate outdoor/supply and return/exhaust chambers inside one insulated galvanized-steel cabinet. Corrugated plates create alternating passages that transfer sensible heat across the metal surface, while internal folds, seals and gaskets minimize air leakage between the two paths. Removable access panels expose the filters, exchanger faces and condensate section for inspection. A sloped drain pan and optional bypass damper support wet operation, free cooling and cold-weather control without dismantling the ductwork.

Key Features

A four-port casing organizes outdoor, supply, return and exhaust connections for direct integration into a balanced ventilation layout.

Corrugated aluminum plates and mechanically folded, sealed edges provide useful transfer area while limiting internal leakage.

Full-size access panels and upstream filter rails keep both exchanger faces reachable for inspection and cleaning.

A sloped condensate section accepts a trapped drain, while an optional bypass path supports economizer and frost-control modes.

Préoccupations du client produit

A complete plate-recovery cabinet must control leakage direction, drainage, frost and maintenance access while fitting four connected air paths into a compact plant-space footprint.

An unfavorable pressure balance can drive residual internal leakage toward the clean supply-air path.Gasketed partitions and sealed plate folds minimize leakage, while maintaining the clean side at the higher pressure directs any residual leakage toward exhaust.

Water retained below the exhaust-side plate face restricts airflow and can contaminate the cabinet floor.Correct core orientation, a sloped stainless drain pan and a properly trapped outlet remove condensate from the wet section.

Winter frost progressively blocks narrow plate channels and upsets the intended supply-to-exhaust balance.A controlled bypass, upstream preheat or staged airflow response keeps the exhaust-side leaving condition above the selected frost limit.

A fixed cabinet installed between four ducts can make filters and plate faces difficult to reach.Removable service panels on the selected access side expose filter tracks, drain components and both faces of the recovery core.
