Harris Calorific supplies a quality line-up of gas welding and cutting torches as well as the super-safe Series 896 and Series 899 oxygen and acetylene regulators. These are the first regulators in South Africa to feature a tamper proof self-reseating internal safety relief valve.
The Series 896 and its gaugeless derivative and the Series 899 save the user in blown diaphragms, ensuring protection from environmental or human interference.
A third regulator, the H25, is high-flow and capable of managing a massive flow of up to 700m3/hr with inlet pressures of 30 000kPa and outlet pressures of 4 000kPa.
