If a deflagration propagates through the clean return line it will make contact with the mesh cartridge which will immediately and passively remove energy from the flame front of the deflagration as it passes through the torturous path of the mesh, forcing the flame to transfer its energy to the high surface area of the mesh, thereby quenching the deflagration and not allowing any flame to pass beyond the Interceptor® -QV® . All of this takes place passively and automatically governed by the laws of physics, there is no reliance on any electromechanical processes, to achieve this result.
The top advantage is the that a passive system is on the job 24 hours a day, 365 days a year. There is nothing to arm and no power source required for the I-QV® to do its job.
Thermal sensing and signaling - monitoring to let you know if the unit has seen flame or a deflagration.
Replaceable mesh cartridge - removable mesh cartridge for easy maintenance without removing the device from the process.
Passive - no moving parts and no maintenance
Stainless Steel Mesh
The quenching cartridge is composed of stainless steel mesh, which absorbs energy to extinguish the deflagration.
