DUPLEX 1400–2400 Silent-N

Versatile compact HVAC units DUPLEX 1400–2400 Silent-N 

Compact rooftop ventilation units with counterflow heat recovery exchanger and integrated sound attenuators. The units are made in two sizes - DUPLEX 1400 and 2400 Silent-N - and are designed for ventilation in all civil and residential buildings where emphasis is placed on quiet operation and reduced built-up space. The integrated sound attenuators and outlets placed directly underneath the unit on the supply and exhaust air side eliminate conventional solutions with HVAC ducting and sound attenuators on the roof.

The units have a base frame with adjustable end pieces for proper levelling and are fitted with vibration insulators to eleminate the transfer of vibrations into the building structures. Several classes of integrated control systems are available including the high-end RD5 series control system with integrated web server and Internet connection, weekly programming, automatic frost protection of the heat recovery exchanger, constant air rate or constant pressure ventilation and power control using sensors (e.g. CO2).
