Duct Heaters

Multi-layer flexible duct Texoflex Black Combi - diameter 127 mm

Texoflex Black Combi, diameter 127 mm. Texoflex Combi is a flexible duct distinguished by its hardness, high flexibility and extremely strong multi-layer walls and it is designed for various application fields. The duct is made of multi-layer polyester laminated aluminium and PVC foil reinforced with high tension steel wire. Due to its exceptional flexibility can be easy installed to round and oval connectors. Texoflex Combi is made for low and medium pressure ventilation systems. Temperature range: from -30º C to +140º C.

0-10V Potentiometer with remote ON-OFF

This potentiometer controls EC fans, AC fan speed controllers or damper actuators. The supply voltage is 3 to 15 VDC. The infinitely variable output signal can be set via a rotary knob without off-position. Via a dry contact, the output signal can be enabled or disabled. This makes remote ON-OFF switching possible. The output range is adjustable via two internal trimmers between Vmin (10—70 %) and Vmax (30-100 %). The splash-proof enclosure allows inset mounting (IP44) or surface mounting (IP54).

Circular fire damper with motor - 100 mm

Circular fire damper with spring return actuator diameter 100 mm. Optimised circular fire damper with a minimum fire resistance of 60 minutes. A minimal pressure loss is guaranteed thanks to the thin blade, the fusible link aligned with the blade, and the transmission located outside the tunnel. Version with spring return actuator ONE 24V (with fusible link) to easily operate Rf-t fire dampers of all sizes, automatically or remotely + unipolar beginning- and end-of-range switch.

Constant Air Volume damper CAV - diameter 100 mm

Constant air volume damper diameter 100 mm. The volume flow controllers VRK are used in complex piping systems for automatically controlling the amount of air distribution. Their task is to maintain a predetermined desired value of the air flow for the supply or exhaust air of a room sustainably and independent from fluctuating channel air pressure. Circular, compact construction with housing made of sendzimir galvanised sheet steel, no overlapping, laser-welded; easy-moving, airtight and maintenance-free control panel with metallic piston vibration damper; resistant to slightly aggressive vapours and solvent; good response and control behaviour in all orientations. Tightness of pipe joints according to EN 12237 Class D Temperature range: -30°C - +100°C

Spiral duct - diameter 100 mm - length 3000 mm

Spiral duct diameter 100 mm and length 3000 mm, galvanised according to the sendzimir process. Suitable for use as extract or supply. Airtight C under the condition that the installation is executed according to EN12237. Galvanised steel DX51D + Z275 (double layered zinc coating 275gr/m²).
