Rectangular heated air dampers Arktos (SVK-NS) are designed to control air flow or shut off air ducts. Arktos SVK-NS dampers are designed for installation on an air intake or an exhaust hood and have tubular electric heaters (heaters) in each joint of the rotary shutters to heat up the joints in case of possible icing of the damper and freezing of the shutters. Heated air dampers are installed in low pressure ventilation systems (with a pressure difference of up to 1500 Pa). Housing parts and shutters are made of galvanized sheet steel. All versions of the dampers are completed with louver turning units made of materials that ensure the operation of the product at temperatures from -60ºС to + 40ºС (sleeves are made of brass, axles are made of carbon steel with zinc coating).
The standard size range of air dampers with heating Arktos consists of 24 dampers with the possibility of manufacturing each in the following versions: SVK-NS in the basic version is supplied without a drive (manual or electric), with a universal platform for a drive (manual or electric). At the same time, a terminal box for connecting heating elements is installed on the valve. SVK-NS + R with a manual drive is supplied with an installed platform for the drive and a drive handle. A terminal box is also installed with the connection of heating elements. SVK-NS K + DRIVE TYPE is supplied with an electric drive installed in an insulated casing. This ensures the operation of the electric drive at a minimum temperature of operation of the valve up to - 60ºС.
The casing is a box-shaped structure made of galvanized steel sheet with a thermal insulating material coating on the inner walls and a self-regulating heating cable placed inside. Cable supply voltage 230 V, power consumption 40 W. A terminal box is installed on the Arktos air valve, in which the switching of the heating elements of the valve, the heating element of the valve drive, and the electric drive itself is carried out. SVK-NS K is supplied only with an insulated casing without an electric drive. In this case, the drive type is not indicated in the designation. The maximum height of the drive mounted in an insulated casing is 85 mm. The production of air dampers with heating is possible with two body thicknesses of 160 and 220 mm in the latter case, the blinds do not protrude beyond the dimensions of the damper.
Arktos valves of standard sizes 1000x2400, 1400x1800, 1400x2400 are equipped with two drive mechanisms. It should be taken into account that the installation of an electric drive on the valve (without additional drive insulation elements) reduces the lower limit of valve operation, which in this case is determined by the lower allowable operating temperature of the drive. When installing a manual drive on the valve, the operating range remains the same - 60ºС to + 40ºС. By special order, it is possible to manufacture valves for other dimensions of the ventilation duct. The maximum height of the valve (dimension "B") is 2400 mm, the maximum length of the valve (dimension "A") is 2500 mm. At the same time, it should be taken into account that air dampers of rectangular section with dimensions on side “A” over 1400 mm consist of two identical sections and are equipped with two drives.
