fire resistance testing of materials used in building construction.

Horizontal Furnaces are designed and manufactured to assess how long a construction element maintains its function, integrity and stability.

These furnaces are used on horizontal testers such as roofs, floors, etc. A loading frame can be added. 

At Ineltec, we design and manufacture customised equipment according to customer specifications, modifying or extending standard features.

According to the UNE-EN 13501 standard, once the fire resistance test has been carried out, excluding ventilation installations, materials are classified according to the data obtained:

  • R: Maintains load-bearing capacity 
  • E: Maintains integrity 
  • I: Maintains thermal insulation
  • W: Complies with radiation criteria 
  • M: Maintain the mechanical actions
  • C: Complies with mechanical  seal requirements
  • S: Complies with smoke-tightness requirements 
  • P/HP: Continuity of electrical signal
  • K: Fire protection capability

Main Structure: made of UPN-IPN-IPE and HEB REINFORCED iron profiles. This structure is covered on the inside with a 4 mm thick steel plate. The structures are fully assembled with all the elements of which they are built, including burners, tubes, transducers, etc. as well as refractory insulation materials. All metal parts are coated with a heat-resistant anticorrosive primer, the exterior finish is painted.

  • Sight Glass: 3 observation windows measuring 100x100 mm made of rock crystal that can withstand high temperatures can be installed (on request).

Isolation: The thermal insulation of the furnace is achieved by a combination of three elements: Ceramic fibre inner lining, the second layer of insulation using refractory bricks and the third layer of refractory bricks of ISO-170/ASTM-33 classification.

The touch screen PC has the PROCAM-WIN installed. It is easy and intuitive software which performs programming tasks, acquisition, records, control and analysis of the results. 

  1. Manual or automatic programming
  2. Possibility of programming date and time of the test
  3. It allows recording notes during the tests
  4. Different access levels
  5. Maximum 11 operators
  6. Display and recording of tests in a graphical or tabular table
  7. Export to excel or similar
  8. Setting of minimum and maximum alarms for temperature and humidity for each section
  9. It includes recording screen, incidences and maintenance.
