Red/yellow/green Color Glass Bulb Fire Sprinkler,all Types of Spray Nozzle Fire Sprinkler Heads

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Automatic Fire Suppression: The sprinkler activates via heat-sensitive glass bulbs (red/yellow/green) that rupture at predefined temperatures (e.g., 63°C), releasing water to extinguish or control fires.
  • Wide-Area Water Distribution: The brass spray nozzle disperses water in radial patterns for even coverage, maximizing fire suppression efficiency.

Key features

  • 1. Corrosion-Resistant Brass Construction

    • With a corrosion-resistant brass body, ensure long-lasting durability in harsh environments*.

  • 2. Color-Coded Temperature Activation

    • With color-coded glass bulbs (red/yellow/green), easily identify and select temperature thresholds (e.g., 68°C/154°F), enabling quick customization compared to fixed-temperature models*.

  • 3. Wide-Area Water Distribution

    • With radial-fin spray nozzles, achieve up to 20% wider coverage than standard sprinklers*, ensuring effective fire suppression across large areas.

  • 4. Versatile Scenario Adaptability

    • With adjustable flow rates and temperature settings, suit both residential and commercial fire protection needs*, offering flexibility unmatched by single-use systems*.

  • 5. Certified Fire Safety Compliance

    • With compliance to fire safety standards (e.g., FM or UL certification), ensure reliable performance in critical situations compared to uncertified systems*.

Product details

Red/yellow/green Color Glass Bulb Fire Sprinkler,all Types of Spray Nozzle Fire Sprinkler Heads

The Red/Yellow/Green Color Glass Bulb Fire Sprinkler is a robust firefighting solution designed for automatic fire suppression. Crafted from corrosion-resistant brass with customizable glass bulb temperatures (red/yellow/green), it ensures reliable activation across diverse environments. The spray nozzle’s radial fins optimize water distribution, while adjustable flow rates and anti-friction coatings enhance performance and longevity.

Customization guide

Adjustable temperature thresholds (red/yellow/green) and flow rates let you tailor the sprinkler to specific fire risks, occupancy levels, or building codes. For example, high-temperature settings (green bulbs) are ideal for industrial facilities, while lower thresholds (red) suit residential spaces.

Get inspired

With its modular design and customizable parameters, this sprinkler system excels in offices, warehouses, and commercial kitchens. Pair its wide spray coverage with adjustable flow rates to protect assets without over-saturating sensitive equipment.

Supplier's note

  1. Technical Breakthroughs:

    • Anti-Friction Coating: Reduces bulb activation friction by 40%, ensuring faster response in critical scenarios.
    • Color-Coded Thresholds: Enables precise temperature customization without recalibration, reducing installation errors.
    • Modular Spray Nozzles: Swappable nozzle designs (e.g., rectangular vs. elliptical) adapt to room layouts.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential/commercial spaces with standard fire risks (e.g., offices). Its fixed temperature and flow rate meet basic compliance needs.
    • Advanced Model: Suited for hotels or hospitals requiring adjustable settings to balance protection and water conservation.
    • Pro Model: Best for industrial facilities (e.g., chemical plants) needing triple the industry-standard corrosion resistance and high-pressure flow rates. With its ISO 9001 certification, it guarantees reliability in extreme conditions.

With the Pro version’s 60 LPM flow rate (+100% vs Base), you can suppress large-scale fires faster than traditional systems. Its military-grade brass ensures longevity in corrosive environments, while customizable nozzles optimize water distribution for unique spaces.
