Rotary Heat recovery core is made of two types of material:
Energy & Heat Recovery Ventilators provide buildings with the best possible balance of energy efficiency air quality and comfort (humidity), Blauberg offers standard air handling units with simplified on-site installation and proven, tested performance. Our air handler solutions deal with such issues as temperature, humidity, pressure control, energy recovery, and air filtration.
Frameless casing design excludes thermal bridges, usual for aluminum or steel frame. This significantly reduces thermal resistance and heat loss, especially for outdoor installation. It also prevents condensation on the surface when air cooling is on. Casing is made of zinc-aluminum coated sheet steel heat- and sound- insulated with 1 9/16″ mineral wool layer for sound reduction.
Benefits of frameless casing:
Better thermal resistance. Lower weight of the unit. No thermal bridges. Suitable for outdoor installation in cold climate. High mechanical strength.
