Möhlenhoff QSK without cover grille
Trench heater as ready-to-install cross-flow fan-assisted System Convector QSK for installation in the
floor area for installation in the screed or optionally for installation in raised floor.
Working principle:
Fan-assisted convection with cross-flow fan.
System trough (floor trough) made of massive aluminium system profile (material: AlMg-Si 05),
corrosion-protected by anodisation. Anodised shade C31, light bronze. Exterior adjustment blocks
(optionally on the interior side) with buffers for acoustic decoupling, adjustable from 10 to 45 mm for
fixing and for fine adjustment of the height.
Heat exchanger made of round copper tubes and pressed-on, rigid aluminium fins, powder-coated in
black and supported in stable, sound-absorbing system bulkheads. Heat exchanger installed in tilted
position. PWW connection ¾“ on the front left side (in view direction towards the window) with
Eurocone connection and venting. Covering of the tube feedthrough with gum mask. 105 °C media
temperature, the medium is water according to VDI 2035.
Internal unit consisting of completely removable heat exchanger and air guide. Hygiene compliant
according to VDI 6022.
Tightly coupled air rolls are driven by only one EC motor per QSK. Thus, the cross-flow fan is built in a
way that an even and effective flow is ensured in parallel and over the entire length of the heat
exchanger. The cross-flow fan with economic EC motor (24V) requires a maximum electrical power of
35 W. Cross-flow fan in sound absorbing, flow-optimised air baffle plate, perforated sheet cover and
coarse filter mat avoid the penetration of small parts into air roll area.
Fan control GS 2000 with sine-commuting motor controller integrated in the convector for lowest noise
development, universal connection for external control systems including BMS, internal bus system for
the interconnection of up to 15 convectors on control-technological basis, speed regulation via 0-10V
signal or external 100k ohm potentiometer, input and output terminals for the through-connection for
bus and supply voltage.
Thermal output tested according to EN 442 or DIN 4704-4-5-1999-10.
Hygiene compliant according to VDI 6022.
Installation cover for the protection of the System Convector during the transport and construction
phase.
Installation instructions available in German, English, Russian, Italian and Danish.
