DUPLEXbase PT 3500

DUPLEXbase PT 3500 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.

Units are supplied with all spigots facing upwards. This can solve the space restrictions issue by connecting the air ducts on a vertical direction which brings up new possibilities for installing the units in normally impractical spaces.

Unique to DUPLEXbase PT Range is the ability to equip the unit on site with optional built-in coils for heating and cooling. This versatile design also allows the unit to be installed as either a left or right hand version. This provides exceptional flexibility for designers in the specification phase and gives contractors the opportunity to locate the unit in the optimum position.

DUPLEXbase PT units are supplied with highly efficient heat exchangers with a large heat exchange area, which achieve a thermal efficiency of up to 93% with a low pressure loss.

All DUPLEXbase PT units benefit from high quality EC fans with backward curved blades designed with energy savings and increased equipment efficiency in mind, the entire range of EC fans not only complies with the ErP 2015 directive for fan requirements but even exceeds them.

The coated steel casing is designed as a frameless sandwich housing with excellent thermal insulation and minimal thermal bridging, making the ventilation units even more economical to operate. According to the EN 1886 classification the units comply with thermal insulation class T2, thermal bridge coefficient class TB2, L2 housing leakage and D1 mechanical stability.

The following additional options are available:

Mechanical ventilation with heat recovery is an important component in creating a healthier living and working environment while contributing to the overall reduction of a building’s carbon emissions whilst increasing energy savings through the reduction of heating costs.
