Hydrant systems with D19 and D25 semi-rigid hose

Hydrant systems with D19 and D25 semi-rigid hose

Fire hydrant system with semi-rigid hose is a very effective fire-fighting facility with an uninterrupted supply of water immediately.

Approved to ČSN 73 0873 and ČSN EN 671-1

Fire hydrant system with semi-rigid hose is a very effective fire-fighting facility with an uninterrupted supply of water  immediately. The design of the system allows quick operation by a single person.

  1. Hydrant cabinet – made of 1 mm steel sheet. Pressurized water supply, brought through the centre of the reel, enabling immediate use of the system. Powder coated surface treatment designed for indoor environment (outdoor design possible by agreement with the manufacturer). Solid or glass-panelled door.
  2. 19 or 25 mm PH – stabil D semi-rigid hose.
  3. Nickel-plated brass ball valve.
  4. D 25 spray fire nozzle consisting of a polypropylene body and revolving head. The revolving head enables the user to set a full or spray stream with an adjustable spraying angle within the range 0 – 110° and to shut off the nozzle.
  5. Connection hose used to connect the system to water main.

System installation

When selecting a specific type of equipment, systems with at least 25 mm hose (internal diameter) are to be installed especially in the following areas:

  • Fire sections in production facilities (according to ČSN 73 0804) and warehouses (according to ČSN 73 0845).
  • Fire sections (buildings) where the linear speed of fire propagation is v1 > 1.2 m/min; values of v1 from Table B.1 in Appendix B can be used without additional certificates.

In buildings or their parts designed as:

  1. Indoor meeting areas (according to ČSN 73 0831).
  2. Accommodation buildings of OB 4 group (according to ČSN 73 0833).
  3. Retail outlets and distribution depots.
  4. Multiple garages.
  5. Exhibition grounds.
  6. Film, TV and radio studios.
  7. Stages, backstage areas, scene-docks.
  8. Fire sections on underground floors with more than 10 persons present (ČSN 73 0818).
  9. Fire sections with high fire load (p > 120 kg/m2).

In other relevant cases, it is sufficient to install hose systems using 19 mm (nominal internal diameter) hose at least.

The hose reel systems are to be installed at a height betw. 1.1 m and 1.3 m above the floor (measured to the centre of equipment). Their position should allow easy reach and it should be possible to open the door up to 180°. For the installation it is necessary to provide sufficient water supply so that a minimum overpressure of 0.2 MPa is guaranteed in the least favourable place.

Application

After opening the cabinet and checking that the nozzle is shut off, open the ball valve on the inlet (the system fills with water). Unwind the required length of hose from the reel up to the place of fire and turn the head of the nozzle to adjust the required shape of water stream.
