CA-Fire Dry Type Cold Room Sprinkler
Fire Fighting Dry Sprinklers Fire Sprinklers For Protection is a high-performance early suppression device engineered specifically for low-temperature and freezing environments, addressing the critical need for reliable fire protection in cold storage facilities, unheated warehouses, and frozen goods storage areas where traditional wet sprinklers risk pipe bursting. This dry pendent sprinkler features a nominal K-factor of 25.2 (363 in metric units) and adopts a fusible alloy activation mechanism, eliminating the requirement for in-rack sprinklers when safeguarding high-stack storage.
Designed to comply with GB 5135.9-2018, Fire Fighting Dry Sprinklers Fire Sprinklers For Protection integrates a natural brass frame, precision-machined flow channel, and corrosion-resistant internal components. Its customizable length (Size B: 152–356mm, Size C: 150–360mm) provides flexibility for system piping design, reducing or eliminating the need for oversized fire pumps. Operating reliably in ambient temperatures as low as -60°F (-51°C), this sprinkler ensures rapid fire knockdown by releasing large, penetrating water droplets once the fusible alloy melts at the rated temperature (74°C), making it indispensable for cold-chain logistics and low-temperature industrial facilities.
Key Features & Advantages
3.1 Sub-Zero Adaptive Dry Design
Fire Fighting Dry Sprinklers Fire Sprinklers For Protection adopts a water-free internal structure that prevents stagnant fluid accumulation, eliminating freeze-related pipe bursts in low-temperature environments. The fusible alloy element is precision-welded to ensure consistent melting at 74°C, triggering immediate activation without false alarms from ambient temperature fluctuations. This design ensures reliable performance in cold storage facilities and unheated warehouses where traditional wet systems are impractical.
3.2 Flexible & Durable Construction
Adjustable Length Options
Corrosion-Resistant Build

Installation & Maintenance
1 Installation Requirements
Pre-Installation Preparation: All installers must complete specialized training; inspect sprinklers for transportation damage before unpacking, and store/unpack individually to prevent collisions.
System Compatibility: Install only after system pressure testing and flushing; use PTFE tape or non-curing pipe thread sealant (hemp is strictly prohibited) for thread connections.
Pipe Length Guidelines: Follow ambient temperature-based exposed pipe length requirements (e.g., 20" / 508mm at -50°F (-46°C), 6" / 152mm at -20°F (-29°C)).
Torque & Handling: Use dedicated tools to apply torque only at the base; do not disassemble, modify, or apply decorative coatings to the sprinkler.
Protective Clip Removal: After installation, carefully remove the protective clip (no violent prying); replace sprinklers with deformed frames, deflectors, or damaged activation elements.
2 Maintenance Protocol
Quarterly Inspection: Check for physical damage, corrosion, or loose connections; verify protective clip integrity (if reinstalled for construction).
Semi-Annual System Test: Conduct a 1.2× rated pressure test for 30 minutes to ensure leakproof performance; flush pipelines to remove debris.
Annual Temperature Adaptation Check: Verify exposed pipe length compliance with current ambient temperature conditions.
Replacement Rule: Replace sprinklers that have been dropped, exposed to extreme impacts, or failed pressure tests-disassembly is prohibited.
