CA-FIRE China Esfr Sprinkler

As a key component of Fire Sprinkler System For Building, the K25.2 Esfr Fire Sprinkler is a high-performance early suppression device engineered for rapid fire knockdown in high-risk storage environments. Designed to tackle fires in palletized, racked, or solid-pile storage facilities before vertical spread, it eliminates the need for in-rack sprinklers in most compliant configurations, reducing system complexity and installation costs.

Patented Fire Suppression Mechanism

The sprinkler adopts a precision-engineered 316 stainless steel deflector with multi-slot geometry, dividing water flow into three targeted paths for uniform coverage and deep fire penetration. Its high K-factor enables high flow rates at lower operating pressures, reducing hydraulic load on the Fire Sprinkler System For Building and minimizing the need for oversized fire pumps.

Extreme Environment Adaptability

With a nickel-plated brass frame and 316 stainless steel components, it resists corrosion in coastal, high-humidity, and industrial environments. The thermal trigger operates reliably across a wide temperature range (-55℃ to 66℃), making it suitable for cold storage applications without performance loss.

System Compatibility & Durability

Long-Term Reliability: EPDM sealing ring maintains leakproof performance under extreme pressure, ensuring a service life of ≥15 years.

Anti-Vacuum Protection: Withstands system pressure fluctuations to avoid deformation or seal failure.

Flexible Installation: Compatible with standard building fire sprinkler piping, supporting threaded connections for seamless integration.

Application & Installation & Maintenance

1. Typical Application Scenarios

This Esfr Fire Sprinkler is a critical part of Fire Sprinkler System For Building in:

Cold Storage Warehouses: Protects high-piled frozen goods without in-rack sprinklers, meeting FM cold storage standards.

Automated Warehousing Systems: Secures robotic rack storage of cartoned commodities and non-foam plastics up to 13.1m height.

Heavy Industry Facilities: Safeguards storage areas for rubber tires, roll paper, and automotive components, resisting industrial humidity and fumes.

2. Installation & Maintenance Guidelines

2.1 Installation Requirements

Pipeline Preparation: Flush pipelines thoroughly before installation; minimum pipe diameter ≥DN25mm for system compatibility.

Spacing Standards: Maintain 2.4m~3.7m between sprinklers; reduce to ≤3m if storage height >7.5m or ceiling height >9m.

Tool & Torque: Use a dedicated ball-mount wrench to tighten to 25~35N·m-avoid pipe wrenches or over-torquing.

Deflector Alignment: Ensure no obstacles within 300mm of the deflector; adjust distance per upright/pendent specifications.

2.2 Maintenance Protocol

Quarterly Inspection: Clean deflector slots with a soft brush; check for plating damage, thermal trigger cracks, or seal leakage.

Semi-Annual Testing: Conduct a 1.2MPa pressure test for 30 minutes to verify performance.

Annual Corrosion Check: Inspect nickel plating for wear; touch up with high-zinc primer if damaged.

Replacement Rule: Replace sprinklers that have been dropped, exposed to extreme temperatures, or failed tests-disassembly is prohibited.
