Fire / Heat Detector – Industrial
An Industrial Fire / Heat Detector is a specialized device designed for use in harsh environments, such as those found in metallurgical plants, refineries, furnaces, and chemical processing areas. Unlike residential smoke alarms, industrial detectors are engineered for extreme temperatures, high dust/particulate loads, corrosive atmospheres, and rapid fire events.
These detectors serve as an essential part of the safety architecture (often feeding into the Emergency Shutdown System, ESD) by providing early, reliable warning of a hazardous condition, allowing for immediate action to protect personnel and valuable Melt Process Systems equipment.
Industrial fire and heat detectors are primarily categorized by the specific fire signature they are designed to detect:
| DETECTOR TYPE | MEASUREMENT METHOD | TYPICAL APPLICATION |
|---|---|---|
| Flame Detector | Senses the ultraviolet (UV) or infrared (IR) energy emitted by a flame. | Open areas, high-value assets, and areas with flammable liquids/gases (fast-acting fires). |
| Heat Detector | Senses abnormally high temperature or a rapid rate of temperature rise. | High-ambient temperature areas (e.g., near furnaces), where smoke is common, or in confined spaces. |
| Gas Detector | Senses the presence of specific combustible or toxic gases (e.g., CO, H₂S). | Processing areas, storage tanks, and confined spaces. |
CLASSIFICATION
- Engineering Focus: Critical Safety Sensor
- Primary Application Focus: High reliability, low false alarm rate, and robust construction; Rapid Alarm Activation and triggering of safety interlocks.
Key Performance Metrics
| PROPERTY | TYPICAL PERFORMANCE | MECHANISM OF ADVANTAGE |
|---|---|---|
| Response Speed | FAST (UV/IR types) | Crucial for mitigating explosions and rapidly escalating fires. |
| False Alarm Immunity | HIGH | Utilizes dual-band sensing (UV/IR or IR/IR Multi-Spectrum) to distinguish real flames from other heat sources (like hot refractory). |
| Durability | EXTREME | Housing is rated for hazardous areas (ATEX/IECEx) and high vibration. |
- Flame Detectors (UV/IR and Multi-Spectrum)
These are critical for rapid response in manufacturing areas.
- UV/IR: The detector uses two sensors: one for UV radiation and one for a specific wavelength of IR radiation (4.4 μm—the signature of hydrocarbon flames). This combination confirms a true fire, rejecting false UV sources (like welding arcs) and rejecting non-flame IR sources (like furnace light).
- Application: Ideal for detecting fires involving gases and light fuels, which often ignite quickly with little smoke.
- Heat Detectors
Heat detectors are simpler and more rugged than flame detectors, making them suitable for environments where smoke is inherent (e.g., near a refractory-curing oven).
- Fixed Temperature: Triggers an alarm when the temperature reaches a predetermined fixed point (e.g., 68°C).
- Rate-of-Rise (ROR): Triggers an alarm if the temperature increases too rapidly (e.g., more than 8°C per minute), indicating a fire rather than normal furnace heating.
- Integration (Handling & Safety)
Industrial detectors are wired directly to a Fire and Gas (F&G) safety panel or the ESD system. Once a confirmed fire is detected, the detector’s output triggers a chain of events (the Safety Interlocks), which may include:
- Shutting down fuel lines to burners.
- Activating fire suppression systems (e.g., foam or water deluge).
- Sounding general alarms and initiating evacuation procedures.

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
Q: Where are the Rabatec refractories and materials produced? | A: Our products are primarily sourced from specialized manufacturing plants in China. Crucially, these facilities have all undergone rigorous audits and achieved comprehensive ISO certifications (Quality, Environment, and Safety), ensuring that production adheres to the highest global standards for consistency and performance. |
Q: What refractory materials does the company offer? | A: We supply a comprehensive portfolio of advanced refractory solutions, including: Shaped Products: Alumina & Silica Bricks, Basic & Specialized Bricks (e.g., Magnesia), SiC & Structural Ceramics, and Precast Shapes. Monolithic Products: Refractory Castables, Mixes & Mortars. Insulation: Insulation Fibre and High-Performance Insulation Products. |
Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
