Difuzor de perete multifunctional TROX CHM

CHM multifunctional wall diffuser

Wall diffusers for supply air, extract air, or as a supply and extract air combination with various diffuser faces, for installation in the ceiling bulkhead or wall, e.g. above doors.

• Wide range of applications due to different diffusers faces and optional additional functions
• Diffuser face with slot diffusers, type PURELINE
• Nominal lengths 550 – 1175 mm
• Easy and tool-free assembly of the diffuser face, e.g. after completion of all preliminary work.

Optional equipment

• Removable optional splitter for improved cross-talk sound attenuation.
• Prepared for room-side mountable volume flow limiter for setting the maximum volume flow rate
• Spigot with damper screen for volume flow rate balancing and/or lip seal
• Mounting bracket for secure wall mounting
• Different looks thanks to colourless anodised or powder-coated slot diffusers and manually adjustable air control blades, optionally in black, white or grey.

Wall diffusers as supply air or extract air diffusers or supply air/extract air combinations for ventilating rooms in ventilation and air-conditioning systems. Consisting of a housing with or without connection spigot for connection to the on-site duct system and a removable front panel.

The front panel serves as a receptacle for slot profiles that are integrated into the front panel. The air is guided via manually adjustable air guide elements integrated in the slot profiles for horizontal or vertical supply air flow. Optional silencer baffles for improved cross-talk sound attenuation.

Can be extended from the room side with a finely adjustable volume flow limiter in round design.

Wall diffusers allow the supply air of ventilation and air conditioning systems to flow into the room, with ceiling influence or directly. The airflow occurs with a high induction of the room air. This quickly reduces the air velocity and the temperature difference between supply air and room air. The result is a mixed ventilation system for comfort areas with good room air circulation and low turbulence in the occupied zone. The wall diffusers are equipped with a removable front plate. The front plate contains front rails type PURELINE, which are supplied with factory-set air control blades. The air control blades can be adjusted manually on site. The different airflow directions allow adaptation to different local conditions at any time. The supply air to room air temperature difference may range from -10 to +10 K. To increase transmission loss and reduce sound transmission into adjacent rooms, the diffuser can optionally be equipped with splitters in the plenum box. Damper blades (optional) in the spigot enable the volume flow rate to be balanced during commissioning. The damper screen is adjusted via the opening for the diffuser face. Alternatively, the wall diffuser CHM can also be pre-equipped for combination with a volume flow limiter VFL. The volume flow limiter is set according to the local system parameters and can be mounted from the room side via the opening for the diffuser face. For an architecturally uniform design, the CHM type can be used as an extract air diffuser or also as a supply and extract air combination.
