TL100DE wall valve with a very discrete design. The front can be painted and wallpapered over. The valve is fitted with strong condensation insulation, overventilation protection, storm protection and filter. Featuring a telescopic inlet duct that can easily be adjusted to the correct length and avoiding the time-consuming cutting torque. The wall lead-through consists of two couplings and a telescopic pipe, 185-340 mm. The couplings are equipped with gaskets, which provide a tight seal against the pipe. The internal valve section and external grille fit on the couplings with snap fasteners. The storm protection prevents energy loss caused by the effects of the wind. Flow is controlled by the front panel, which has a mechanism to change the opening angle. The front panel opens at the top edge and forces air upwards, which provides a convenient diffusion area, even with underfloor heating. The valve should be installed high up on the wall, preferably above a radiator if one exists. This location uses the convection current to achieve optimal comfort. The valve is perfect for use with underfloor heating as this is what it is designed for. TL80DE Soundproofing. The sound absorbing wall lead-through consists of a sound absorbing pipe instead of the standard wall pipe. The sound absorbing pipe is easy to cut to the correct length with a snap-off blade knife. Standard pipe length 360 mm. The internal valve section is fitted with strong condensation insulation, a filter and a front panel that tilts up at the top edge to adjust the flow. The filter is mounted in a filter cartridge, which is also equipped with a guard to prevent the ingress of water. The front panel has four opening positions to vary the flow. The diffusion area has been carefully designed for use with underfloor heating systems, the valve allows the air to escape upwards and to the sides. The addition of indoor air is extremely efficient – very cold air quickly reaches a comfortable temperature just a few decimetres from the actuator.
