Furnaces

Fire Resistance Test Furnaces

Fire resistance test furnaces developed to meet the requirements of authorized test laboratories for verification and proof of fire rating. Fully automatic, built for decades of accredited operation.

Built for Accredited Fire Testing

What the Furnaces Test

  • Fire doors & shutters
  • Walls & partitions
  • Load-bearing elements
  • Columns & beams
  • Ventilation ducts & dampers
  • Cable barriers
  • Glazed screens
  • Penetration & linear joint seals
  • Ship decks & bulkheads
  • Tunnel sections
  • Lift landing doors
  • Aviation components

Five Furnace Configurations

Five configurations cover the full scope of fire resistance testing. Every configuration is fully automatic with manual override, with pre-cast refractory blocks for rapid repair and long-life refractory lining.

    Modular 2 × 1 m architecture
  • Configuration
    Indicative
    Orientation
    Both
    Typical use
    R&D and pre-certification trials
    Key characteristic
    Compact 1.5 × 1.5 × 1.5 m chamber

One Furnace, Every Major Fire Curve

  • Furnace pressure control: ±2 Pa within the specified pressure range
  • Fire curves: ISO 834, slow heating, HC, HCM, RABT, RWS and project-specific curves
  • Maximum temperature capability: up to 1,350 °C, depending on furnace configuration
  • Burner power: configurable according to furnace size and required fire curve
  • Control: fully automatic PLC/SCADA operation with manual override
  • Fuel options: natural gas or light fuel oil, according to project requirements

Maximum temperature, burner power and curve set are specified per project; 1,350 °C is the capability ceiling of the range, not the rating of every furnace.

Standards and fire curves

Built for Decades of Service

Refractory Construction

  • High-alumina refractory materials selected according to furnace temperature and duty
  • Insulating refractory layers designed to reduce heat losses and external surface temperatures
  • Low-thermal-mass construction for controlled thermal response
  • Modular refractory design to facilitate inspection, maintenance and replacement
  • Engineered expansion joints to accommodate thermal movement and reduce deformation

Steel Structure

  • Heavy-duty welded steel structure engineered for repeated thermal cycling
  • Structural design adapted to furnace dimensions, specimen loads and laboratory configuration
  • Furnace casing and reinforcement designed for dimensional stability during testing
  • Accessible construction for inspection and maintenance
  • Surface protection and finishing according to project and environmental requirements

Independent PLC per Furnace

All functions are controlled by an independent Siemens SIMATIC S7-1500 PLC for each furnace, with an audible and visual alarm system, full data logging and remote diagnostics. Temperature, pressure and actuator data are logged for the complete test record.
