Thomas - Vertically Driven Automatic Barrier, Manual Reset

The TÜV and VdS tested and certified firewater barrier consists of one left side U-profile and one right side U-profile as well as an aluminum, multi-chamber profiled barrier which is thermally and mechanically resistant. A counter balancing weight is located in a rectangular pipe. When not in use, the barrier is held in the upper position magnetically. If power is lost, the weight-compensated closing of the barrier begins by means of a flow control unit. When the metal barrier has been lowered to the horizontal, closed position it is automatically locked into place. Unlocking of the clamps and resetting of the barrier to its upper position occurs manually. This product is protected by patent.
