Welcome the next generation of ventilation: DUPLEX Pro-X replaces the proven EC5 units

For many years, the ceiling-mounted heat recovery units of the EC5 series have been among the most frequently specified solutions in your projects. Now, however, the time has come for an innovative step forward.

We are proud to introduce the brand-new DUPLEX Pro-X series, with nominal airflow rates of 370 and 570 m³/h, specifically designed for houses and apartments.

This new series offers an outstanding combination of high heat recovery efficiency, exceptionally energy-efficient operation and remarkably quiet performance. What improvements can you look forward to with the Pro-X series?

Key advantages of the new generation

• Easier installation: The units require less installation space, making them an ideal choice for installation in suspended ceilings with limited space.
• Innovations for installers and service technicians: A completely new and highly practical feature is the adjustable hinge position. This detail significantly improves access to the unit during installation and regular maintenance.
• Quieter operation: Although the EC5 series was known for its quiet operation, internal improvements make the Pro-X series even quieter, with sound power levels radiated to the surroundings starting at just 36 dBA.
• Energy-efficient operation: We did not stop at achieving the highest energy efficiency class, A+. The new Pro-X series delivers more efficient heat recovery and lower fan energy consumption.
• Proven solutions from the Pro family: Like the other residential units in the Pro series, these units feature connection spigots designed to minimise thermal bridges and access openings that allow filter replacement without opening the unit's access panel.
• Optional accessories: Integrated air preheating and reheating options are available.

The DUPLEX Pro-X series is therefore more than a worthy successor to the 370 and 570 EC5 models.
It perfectly complements our current family of ceiling-mounted residential ventilation units, which now rests on three strong pillars: Pro, Pro-X and Easy2.
