Trafficable line bar grille above 1 or 2 slot linear floor diffuser with high induction alternating jet discharge and low velocity vertical air pattern with displacement spread across the floor. Suitable for installation against facade.

	Location – below: Air supply from the floor, typically at least 200 mm from seated occupants.
	Displacement airflow: Thermal displacement room airflow, with low-level, high induction alternating muliti-jet mixed flow supply for rapid discharge velocity and temperature differential decayto head height in the occupancy microclimate. Displacement airflow spreads gently across the floor. Heat and contaminants rise by natural convection in thermal plumes to stratify at a high level. Enhanced levels of indoor air quality are attained in the breathing zone.
	VAV dependent throw: Suitable for VAV applications. Throw height is dependent upon airflow rate.
	Face shape: Rectangular
	Face pattern: Trafficable linear bar grille.
	Metal Face: Powder coated steel.

Options

Plenums: Side or bottom entry connection boxes.

For offices, community facilities or living rooms: Highly inductive floor-mounted linear diffusers LDU-W ventilate, heat and cool rooms comfortably and draught-free, even with high temperature differences between supply air and indoor air.

Type LDU-W:      Linear air diffuser with foot traffic-resistant grille
Type LDU-W/H: Linear air diffuser with foot traffic-resistant grille and integrated reheater

• Quiet and draught-free with highly efficient ventilation
• Energy efficient: Thermal shielding of glass façades
• LTG SystemDesign : permits different technical solutions for room air conditioning in different building areas under a visually consistent grid, also continuous banded appearance
• Flexible design of exhaust grid
• Ideal for raised access floors and hollow floors, easy to mount

The visual appearance and impact within the indoor environment are primarily determined by the architecture. LTG SystemDesign makes it possible to implement various air-conditioning solutions in different building areas based on a uniform visual pattern.

In many cases, varying conditions and comfort-related requirements demand the use of different ventilation and air-conditioning systems in one and the same building. Previously, the different systems also looked different. LTG’s SystemDesign for floor-mounted units solves this problem. Different units for different air- conditioning systems can be concealed behind exactly the same ventilation grille and give the rooms where they are installed a harmonious visual appearance – bringing many advantages for investors, architects, planners and process engineers alike.

For architects, they are the answer to a long-standing need: the grilles can be mounted as a continuous strip and – being available from a width of 200 mm – are comparatively narrow. They are available in a range of materials and colours. The discharge grilles are positioned directly at the facade.

The floor cutouts for all the units integrated in the LTG SystemDesign are identical. For planners, this simplifies the planning of the building, while investors save on the cost of construction work.

All the units of LTG SystemDesign have the same structure. While process engineers appreciate the simplified assembly and maintenance this brings, investors again benefit from reduced costs. A major advantage for investors and landlords is the ease with which the air-conditioning and ventilation technology can be adapted, for example when a room is used for a different purpose. And this remains true in the event of a retrofit or conversion.

Products that use LTG SystemDesign:  HFB, VKB, SKB, FVD and FVPpulse.
