DN52 recessed fire hydrant with space for a fire extinguisher next to the hose reel, 20m flat-folding hose, padlock, white color RAL9003 S-52-B1G6G20-P-9003

Internal fire hydrant DN52 – reliable fire protection

This recessed internal fire hydrant DN52 is a comprehensive solution for fire protection in buildings. Equipped with a 20-meter flat-folded hose and a padlock, it provides quick and effective access to water in case of danger. The hydrant design allows for installation in both left and right versions, increasing its versatility.

Construction and application

The hydrant is designed for installation inside buildings, in places requiring easy access to a fire extinguishing water source. The recessed version (B) with a flange facilitates aesthetic installation in the wall. Additional space for a fire extinguisher next to the hose reel allows for the creation of a comprehensive fire station. Suitable for operation at a pressure of 0.2 to 0.7 MPa, it ensures stable operation in typical water supply installations.

Key features and benefits

• Durable connections: The hose connectors are made of aluminum sleeves instead of traditional wire, which guarantees exceptional durability and tightness of the connections – minimizing the risk of failure during critical situations.
• Universal mounting: The ability to choose between left or right versions and different connection holes (from the side, from the back, from the top) makes it easier to adapt to specific installation conditions.
• Complete equipment: The set includes everything necessary for quick hydrant operation: a 20-meter flat-folded hose, a PWh-52 hydrant nozzle and a padlock.
• Compliance with standards: The product meets the requirements of PN-EN 14540:2005(U) and PN-EN-671-2 standards, which confirms its safety and reliability.
• High efficiency: The hydrant provides an efficient water flow – up to 299 l/min at a pressure of 0.6 MPa – which translates into effective fire extinguishing. The effective range of the water jet is up to 19.8 m (at a pressure of 0.6 MPa and a hose length of 20 m).
• Aesthetics and coating durability: The coating with polyester facade powder paint in white RAL9003 provides corrosion resistance and aesthetic appearance for long-term use. The cabinet door opens 180º thanks to the use of a concealed hinge.

Information on hydrant performance at different pressures:

At a pressure of 0.2 MPa: the flow rate of the diffused stream is 172 l/min, and the solid stream – 155 l/min; the effective range of the water jet (with a 20m hose) is 10.8 m.

At a pressure of 0.4 MPa: the flow rate of the diffused stream is 244 l/min, and the solid stream – 220 l/min; the effective range of the water jet (with a 20m hose) is 17.1 m.

At a pressure of 0.6 MPa: the flow rate of the diffused stream is 299 l/min, and the solid stream – 270 l/min; the effective range of the water jet (with a 20m hose) is 19.8 m.

This hydrant is an investment in the safety of the facility and its users. The solid construction and compliance with applicable standards guarantee reliable operation in emergency situations.
