Chemical structure:

At normal temperature, TPD-5112 is a colorless, transparent and insulating liquid. It is the novel environmental harmonic and clean extinguishing agent.

TPD-5112 is a novel substitution of halon extinguishing agent. It helps engineers and facility managers meet environmental regulations while helping ensure the safety of people, reduce risks and preserve business operations with minimal downtime. It features zero ozone depletion potential (ODP) and a global warming potential (GWP) of less than 1. 

TPD-5112 also has the largest safety margin for use in occupied spaces of all clean agents. It effectively extinguishes fire faster than inert gas or water mist systems, requires less volume of fluid and is safe for use with electronics.



  • Meets the most stringent international environmental regulations
  • Has a dielectric strength up to (3mm) 74.6KV and has passed the electrical insulation 
  • performance test of 110kV
  • Has a unique cooling effect after discharge
  • Volatilizes quickly after use, which will not cause damage to precision instruments, antique calligraphy and paintings
  • It is liquid at room temperature, easy for filling, transportation and storage, also be transported as non-dangerous cargo
