DUPLEX 1500–5500 RS5

Versatile compact HVAC units DUPLEX 1500–5500 RS5 

Custom-made compact AHUs for indoor installation. Their innovative circulation design provides complete ventilation with simultaneous indoor air circulation. The units are designed for rooms where hot air heating is suitable or necessary, for instance where conventional heating systems cannot be used due to interior design constraints (rooms where no heaters or radiators should be installed) or where it is impossible to cover the entire heat loss volume (underfloor heating with limited capacity).

The units also provide an advantage for low-energy buildings where the room temperature climate must be balance quickly, for instance due to sudden heat gain from sunshine, which conventional heating systems (primarily underfloor heating systems) are unable to achieve with the speed required. The circulation air from the unit can transfer high heating or cooling capacity, which obviously matches the air rate of the unit. The compact dimensions of the units put only minimum demands on the engine room space. The units are always supplied for installation under the ceiling and the space saved can be subsequently used for other purposes including storage. Their well-thought-through design makes it possible to change the position of discharge outlet downstream of the supply fan (e2 + c2), the position of the service switch and the connections of registers for cooling or heating the supply air.

There are up to 32 different configurations available. All DUPLEX RS5 units meet the requirements of Commission Regulation (EC) 1253/2104 (Ecodesign) in force since 2018 and their characteristic features include high heat recovery efficiency and the low power input of the fans. DUPLEX RS5 units normally come with sophisticated control system RD5, offering an option to connect to the Internet and have remote diagnostic and control features.
