The THERMOMAT is a multifunctional safety device for use in oxy-fuel technique.
It is fitted with the following safety elements:
The flashback arrestor, as main constituent of this safety device, consists of
sintered stainless steel with an accurately defined porosity which ensures an
unrestricted through-flow at normal operation. Running-in flashbacks are kept
back absolutely reliable due to sintered metal. The flame goes off immediately.
The non-return valve avoids a gas reverse flow of the discharged gas and
prevents any build-up of potentially explosive gas mixtures at the inlet side.
The thermal cut-off valve cuts off gas supply in an irreversible manner in case
the device warms up to an undue high temperature, e. g. if a burnback on the
surface of the flashback arrestor occurs.
Located on the inlet side of the device’s flammable gas version, a dust filter
protects the non-return valve from infiltration of impurities, e. g. due to levitating
tiny particles in the gas.
