Hydrant foam system with D33 semi-rigid hose is yet another of the certified fire fighting systems marketed by Pavliš a Hartmann. This product diversifies the complete line of D19, 25 and 33 hydrant systems and the D25 foam-inducing system with semi-rigid hose with yet another already certified foam inducing system.

The system includes

  1. Steel cabinet with a reel (W 1190 x H 800 x D 340) surface treated with RAL 3000 (red) or RAL 9001 (white) powder coating for indoor environment.
  2. D33 admixer for HS application with a ball valve.
  3. D33 connecting hose, 1.4 m long.
  4. D33 hose, 20 or 30 m long.
  5. Tank with foamer (20 L).
  6. Fire foam inducing nozzle for heavy foam with a ball valve.
  7. Suction hose with stainless steel tube.

Application

The hydrant foam inducing system is designed for initial firefighting using heavy foam. The contents of foamer can be used for the period of 7 minutes at least. The system is normally equipped with a jet for the application of 1% foamer which is included in the delivery.

The tank with foamer can only be opened in the case of an action. Otherwise there is a danger of foamer degradation.

The equipment can also be used for firefighting using water. In such a case, the suction valve of the admixer shall be closed.

After each action with the use of foamer, the whole system is to be flushed with clean water by removing the suction stainless-steel tube from the tank with foamer and inserting it in a tank with clean water. Then open the suction valve of the admixer and flush the whole system thoroughly.

The equipment is designed for frost-free indoor environment. Water – foamer 3%

Description of the system

The hydrant foam inducing system includes a reel with D33 semi-rigid hose max. of 30 m on a swinging arm installed in a cabinet, 1.4 m connecting hose of the same diameter, D33 fire nozzle for heavy foam, admixer with the main ball valve and a 20-litre tank with foamer.

The nozzle (equiv. to 10) includes the body made of light weight alloy with holes for air suction and plastic coating for safety grip and protection against cold, and a DN33 lever-operated ball valve with connecting thread G1 1/4”. The positions are marked with arrows and symbols ON-OFF.

The admixer is installed before the reel. It includes a body with diffuser of brass, a 3/8” ball valve of the foamer suction system with a replaceable jet and suction hose ended with a stainless tube. In case of an action, this tube is inserted into the tank with foamer located in the cabinet.

At the inlet, the admixer is fitted with a DN33 ON-OFF ball valve and at the outlet with male thread G1 1/4” to which the connecting hose is fastened. The direction of water flow is marked with an arrow on the admixer body.

The cabinet is made of steel sheet with textured RAL 3000 tint powder coated surface. Cabinet dimensions are 1190 x 800 x 340 mm. It is divided into two parts. One part contains the reel with hose and the nozzle and the other part houses the admixing equipment and a 20-litre foamer tank.

Two variants of the system are available. The left hand version has the water inlet and tank in the left hand part of the box while the right hand version has these on the right hand side. The closing system is secured with a plastic lock allowing the application of a seal. The cabinet is designed for indoor environment.

Installation of the system is similar to that of the other fire hydrant systems manufactured by Pavlis a Hartmann.
