Fire Hose Testing Device – Leak tightness and pressure retention tests according to DIN 14521, NF S61-820

ZONSKY's Fire Hose Reel Testing Device is designed to assess the airtightness and pressure retention capabilities of fire hose reels. This apparatus subjects the hose reel and its connections to high-pressure water tests to detect leaks and verify sealing integrity.

Product applications: It is suitable for testing the sealing performance, pressure resistance, outer diameter expansion rate, and axial elongation rate of fire hose reels with water, dry powder, and foam fire extinguishing agents. It is applicable to a maximum working pressure of 0.4 MPa, with a maximum hose diameter of 38 mm.

Complies with standards: DIN 14521-1987, NF S61-820-1/IN12010, NF S61-820-2/IN12010.
