Pressure Reduction Box
Round connecting nozzle with square pressure reduction box (acts as sound attenuator). Casing made of galvanised sheet steel in double walled design with thermal and acoustic insulation. A 4-spoke calliper with 12 measuring points ensures a measurement accuracy of ±5 %. The Barcol-Air damper leaf (double layer with SBR seal in-between) is mounted in low-friction nylon bearings. Shaft material: aluminium. The reheater battery has copper pipe connections (for solder or plug-on connection), each fitted with a drain or vent valve.
