Description
GTL-50 Fire-Retardant Coating Thermal Insulation Efficiency & Fire Resistance Rating Test Furnace
1. Product Overview
The GTL-50 Test Furnace is a dedicated laboratory testing furnace developed strictly in accordance with GB14907-2018 Fire-retardant coating for steel structures and GB/T9978-2008 Clauses 4 & 5 (5.1, 5.2). It is specially designed to detect the fire resistance performance, thermal insulation efficiency and fire resistance grade of fireproof coatings for steel construction materials.
This furnace adopts intuitive touch screen independent control, no extra computer or software installation required for daily operation. The whole testing process is fully automated with simple operation and easy maintenance. All temperature control error indicators are superior to national standard requirements, delivering stable, high-precision test data for fire coating manufacturers, third-party testing labs and construction engineering institutes.
