SKU: 90001587


DUPLEXbase PS 1100 is designed for the energy efficient, comfort ventilation of schools,restaurants, sports halls, shops, and offices as the unit has a powerful air delivery with low energy consumption and exceptionally high thermal efficiency. With a range of control options including Internet and BMS compatibility for "On Demand" ventilation the unit also incorporates an automatic, 100% summer by-pass to isolate the heat recovery function during the hotter months.

Unique to DUPLEXbase PS Range is the ability to position the unit on the floor or in a ceiling-suspended configuration, indoors or floor-standing outdoors (accessories required).
