Katherm QL
Displacement ventilation system for draught-free ventilation.Overview
Katherm QL trench convectors stand for low-turbulence room air. They effectively supply the room with conditioned, fresh air as low-turbulence displacement air.
The displacement air enters the room at a low air velocity of less than 0.3 m/s and is distributed within the room as a low-pulse, draft-free air flow for maximum comfort in the occupied zone.
Alongside the proportion of displacement air, air heated by the coil rises up the glass façade, efficiently shielding it from a drop in temperature.
Two trench widths and heights and five trench lengths are sufficient to ensure optimum comfort in projects with the Katherm QL.
By eliminating rotating parts, the investment costs are kept low. Maintenance is also very simple.
Custom-made products are possible for any building architecture with individual geometries. This applies to the channel and the grating. Mitred corners, curved designs, angles and slopes, column recesses, various grating variants and frame edges are available. Let us advise you.
The Eurokonus valve connection enables the Katherm QL to be quickly and easily installed on site. In addition, height adjustment feet and raised floor height adjustment feet are supplied as standard to further reduce the installation time and thus the cost.
High-output Cu/Al convectors with two convector widths 70 and 100 mm and two convector heights 50 and 100 mm.
In heating mode, a barrel of air is formed on the façade above the convector, which effectively prevents a drop in temperature on the surface of the window and supplies the room with heat. It does so at the same time meeting the most exacting demands for a comfortable air flow.
The displacement air design consists of integrated eccentrically mounted and adjustable air deflection rollers, a row of holes and deflector plates for a uniformly directed and low-pulse displacement air outlet. Supply air nozzles for air intake are fitted laterally along the trench length.
The treated displacement air is fed into the room at low turbulence through the large air outlets in the floor and is distributed in the room at very low air velocities.
