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.
01Vertical Fire Resistance Test Furnace
Large-scale fire resistance testing for walls, doors, façades, glazing, penetration and joint systems, ducts and dampers.

One Furnace, Every Major Fire Curve
- Furnace pressure control ±2 Pa at 20 Pa range, stabilized within 10 minutes
- Curve library: ISO 834, slow heating, HC, HCM, RABT, RWS and custom curves up to 1,350 °C
- Burner power option up to 12 MW for HCM and RWS curves
- Fully automatic control with manual override
- Gas-fired or light-fuel-oil-fired
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 curvesBuilt for Decades of Service
- Pre-cast, pre-cured refractory concrete blocks: long service life, rapid repair without full relining
- Side walls in JM 23 / JM 28 insulating brick, backed by Ca-Si plates; roof and floor in low-thermal-mass, high-temperature concrete
- Fabrication to EN ISO 3834-2; all structural welds 100 % NDT tested; sandblasted and primer-coated
- Engineered thermal expansion margins prevent deformation during heating
- Minimized heat loss, so energy consumption per test and NOx emissions are lower
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.
