Product Description
The DHST022 Easy Maintenance Fire Nozzle is a cutting-edge firefighting solution engineered to deliver high performance with minimal downtime. Designed for industrial, municipal, and emergency response scenarios, this nozzle combines advanced engineering with user-friendly features to ensure optimal fire suppression efficiency. Its innovative design prioritizes quick maintenance, reducing operational costs while maintaining compliance with international safety standards like NFPA 1963-2025 . Ideal for high-pressure applications, the DHST022 is trusted by fire departments and industrial facilities worldwide for its reliability and durability.
The DHST022 features a modular construction that allows for easy disassembly and cleaning. Key components, such as the nozzle tip and internal valves, can be replaced in minutes without specialized tools, minimizing maintenance time by up to 40% compared to traditional nozzles . This design reduces downtime, ensuring the nozzle remains operational during critical emergencies.
With a maximum working pressure of 2.5 MPa (363 PSI) and a flow rate range of 50–200 GPM, the DHST022 is capable of handling high-intensity fires. Its precision-engineered nozzle tip optimizes water distribution, creating a focused jet for structural fires or a wide fog pattern for vapor suppression .
Constructed from marine-grade brass and stainless steel components, the DHST022 resists rust and chemical degradation, making it suitable for harsh environments like petrochemical plants and coastal regions. The exterior is coated with a durable epoxy finish to withstand extreme temperatures (-30°C to 150°C) .
The ergonomic, non-slip grip ensures comfortable handling even when wet or gloved. The lightweight design (only 3.2 kg) reduces operator fatigue during prolonged use, enhancing maneuverability in high-stress situations.
The DHST022 meets all requirements of NFPA 1963-2025, including rigorous testing for pressure resistance, leak tightness, and durability. It also carries UL certification, ensuring compliance with global safety standards .
Industrial Firefighting: Ideal for factories, warehouses, and power plants, where high-pressure water streams are essential to suppress fires in machinery or storage areas.
Municipal Fire Departments: Used by first responders for structural firefighting, wildland fire control, and emergency rescues.
Marine Environments: Resistant to saltwater corrosion, making it suitable for shipboard firefighting systems and offshore platforms.
Chemical Spills: The fog pattern effectively suppresses flammable vapors, protecting personnel during hazardous material incidents.
Q: How often should the DHST022 be serviced?
A: Routine maintenance is recommended every 6 months or after 50 hours of use. Check for wear on seals and replace them if necessary.
Q: Can the nozzle be used with foam solutions?
A: Yes, the DHST022 is compatible with aqueous film-forming foam (AFFF) and protein-based foams. Rinse thoroughly after use to prevent clogging.
Q: What is the warranty period?
A: The DHST022 comes with a 5-year warranty covering manufacturing defects. Wear parts like seals are excluded.
Q: Is training required to operate the nozzle?
A: Basic training is recommended to familiarize operators with flow adjustment and maintenance procedures.
Q: Can the nozzle withstand freezing temperatures?
A: Yes, the DHST022 is tested to operate at -30°C. Ensure proper winterization by draining residual water after use.
