FLP (Flameproof) Heaters

Operating heaters in explosive areas can bring risks like sparks or failures that threaten safety and halt production. Our FLP (Flameproof) Heaters are crafted to solve these concerns, providing safe, steady heat in dangerous environments where flammable gases or dust are present.

Heating Element Material

Nickel-Chromium (NiCr) alloy or Stainless Steel (Grade 316/321) for reliable heat output

Sheath/Outer Material

Stainless Steel (SS 316/321) or Cast Aluminum (flameproof enclosure) for explosion safety

Voltage Rating

110 V – 240 V (single-phase); up to 690 V (three-phase) for industrial hazardous areas

Power Rating

1 kW to 100 kW, scalable based on application and enclosure size

Temperature Range

-20°C to 200°C (standard hazardous areas); up to 400°C for high-temperature processes

Product Description

Unsafe designs or wear from harsh conditions can lead to costly downtime and safety issues in volatile settings. Our flameproof heaters tackle these problems with a tough enclosure made of stainless steel or cast aluminum, locking in sparks and heat.

Heat-Up Time

10 to 30 minutes to reach target temperature, depending on power and ambient conditions

Watt Density

2 W/in² to 20 W/in², optimized for safe heat distribution in explosive environments

Insulation Material

Magnesium Oxide (MgO) or Ceramic for high-temperature insulation and electrical safety

Corrosion Resistance

High resistance to moisture, chemical vapors, and explosive gas/dust exposure

Dimensions

Length – 300 mm to 2000 mm; Width – 150 mm to 600 mm (customizable per enclosure design)

Shape/Configuration

Tubular (straight or U-shaped) or finned; enclosed in flameproof housing

Current-Carrying Capacity

5 A to 150 A, depending on power rating and conductor sizing

Heat Transfer Method

Convection (air heating) or Conduction (surface/fluid heating); contained within enclosure

Mounting/Fitting Type

Flange, threaded boss, or wall-mounted flameproof enclosure; fits hazardous area setups

Safety Features

Flameproof enclosure (Ex d), overheat protection, grounded design, explosion containment

Standards Compliance

Meets or exceeds UL 1030, IEC 60335-1, EN 60079-1 (Ex d flameproof), EN 60204-1 (electrical safety), IECEx, ATEX, and ASME B31.3 standards

Technical Advantages

Heating in hazardous zones demands equipment that prioritizes safety without losing power. Our FLP heaters use a flameproof design that traps any sparks or explosions inside, paired with durable materials to resist chemical vapors.
Reliability in explosive areas goes beyond just containment, it needs consistent performance too. These heaters work with voltages up to 690 V and include overheat protection, ensuring steady operation even in extreme conditions.
