Product Introduction

This high-volume cabinet uses a broad rotary matrix and a 1990 x 2259 x 2642 mm enclosure to recover energy from central balanced ventilation. Rectangular connections and large fan sections suit clean manufacturing or healthcare buildings with several zones and long distribution ducts.

Key Features

Building-scale recovery

The large wheel captures sensible and latent energy from a high-volume extract stream before outdoor air reaches downstream conditioning.

Central duct compatibility

Rectangular interfaces connect directly to large supply and extract mains without round-to-square transitions.

Large service compartments

Separated filter, wheel and fan zones provide defined access for central-plant maintenance.

Applications

Large clean manufacturing plants, hospital ventilation systems, pharmaceutical buildings and central laboratory facilities with balanced air streams.

Solutions for Your Application

Conditioning a large outdoor-air volume creates a major annual energy load.Use the broad rotary matrix to transfer available sensible and latent energy from the central extract stream.

Large recovery equipment must integrate with rectangular main ducts and service pathways.Coordinate connection faces, cabinet splits and component-removal clearances before the plant layout is fixed.

Available Options

Large filter banks, hydronic coils, wheel purge arrangement, variable fans, attenuators, weatherproofing and supervisory controls can be selected.
