Tube Type Automatic Fire Suppression Systems

PRI-SAFETY Tube Type Automatic Fire Suppression system is a special polyamide tube, the out Dia.18mm, and different length as required, it is a compressed gas-extinguishing FM200(HFC-227ea) or FE-36(HFC-236fa), called Heptafluoropropane or Hexaflluoropropane too. In normal temperature, the tube pressure is 2~6bar. But the pressure will be increasing with the temperature increasing, when temperature reach to 100° C, the FM200 expansion to 15bar. When the temperature reach to 120° C, the softened tube burst a round hole to release the extinguishing agent to extinguish the fire in very short time.
