DUPLEXbase PS 1700

DUPLEXbase PS 1700 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). This versatile design also allows the unit to be installed as either a left or right-hand version. The front door enables easy access to all components. Inlet and outlet ports are rectangular. The unit has separate doors which allow for an easy filter change.

The casing thickness of 30 mm, is made of: – Steel sheet with aluzinc coating AZ 185 (corrosion class C4 according to EN ISO 12944-2) and a thickness of 0.8 mm – Polyisocyanurates (PIR) 30mm – Heat transfer coefficient =0.024W/mK Housing properties according to DIN EN 1886: – Mechanical stability: D1 – Housing leakage: L2 – Thermal insulation: T2 – Thermal bridge class: TB2 Building material class according to DIN EN 13501: B-s2-d0 Condensate tray with integrated stainless steel tray.

This provides exceptional flexibility for designers in the specification phase and gives contractors the opportunity to locate the unit in the optimum position.

Extracted air filter: Type of filter: ePM10 50% (M5) pleated cartridge Dimensions: 600x380x96 mm Number: 1 pcs All filters are ISO 16890 compliant.

100% automatic summer bypass damper: A bypass damper is fitted in the ventilation unit as standard and designed to bypass the heat exchanger during hot seasons to avoid overheating in the ventilated premises. In addition, the damper can also be used for night pre-cooling. Moreover, the summer bypass can be used to prevent the plate heat exchanger from freezing (defrosting using bypass). If required, an option of intelligent cool recovery is also available. Frame made of zinc-coated metal (class 2, thickness 1 mm), flap with tight-closing Aluminium blinds.

Heat recovery feature: Wide-area counterflow plate heat exchanger from high-impact polystyrene (hPS) provides high efficiency of heat recovery and it is resistant against corrosion to a high extent. Furthermore, it is chemically stable when in contact with extracted air that is polluted from a wide range of applications. The exchanger is resistant against impurities, and it can be operated in the temperature range from -25°C to +80°C. It features class H1 according to DIN 13779.
