Louver made of aluminum profile.
The dampers can be mounted inside, or outside of the section. The frame around the perimeter of the damper is made of galvanized steel.
Rotating mechanism – cog wheels made of polycarbonate, mounted inside the frame, protected from external environment conditions. Square rod for automatic actuator. Two rods installed if damper height is more than 1200 mm. Air tightness class 3 according to EN 1751.
Option: «Northern» execution.
For the regions with the outside air temperature below -40°C provided an electric heater between the blades. Heater protects blades and cogs from icing.
Recommended accessories: BELIMO electric actuators:
|Flexible anti-vibration insert|
Flexible connectors are two flanges interconnected by antvibration material. The inserts are made of galvanized steel and polyethylene tape reinforced with polyamide textile cloth.
In unit and air ducts connections to reduce vibration in the air ducts.
Additional protection from precipitation is applied to unit construction in case of outdoor execution.
Protects the unit from external influences: water, sand, leaves, others.
Visor is equipped with a protective grid. Hood length is 300 mm. All joints are sealed.
|Electric heater controller|
|Triac controller provides smooth regulation of electric coils heating power. Max heating power up to 75 kW (25 kW triac + two steps 25 kW each).|
|Pressure differential switch indicates an error in case of clogging of air filters, breaking of belts in centrifugal fans, low air flow through electric heaters, etc.|
|Duct thermostat indicates the threat of fluid freezing in water coils.|
|Variable frequency drive|
Danfoss inverters provide smooth regulation, soft start, and active overheating protection of asynchronous fan motors. Inverter can be supplied loose or mounted inside the fan section. It is recommended to use VFD for both belt driven and direct driven plug fans.
|Water mixing set WMG|
|WMG controls power of water heating and cooling coils by regulating the temperature of water on coil inlet. WMG consists of 3-way valve with modulating 0-10V actuator and circulation pump.|
