Pyrozone

The PyroDeTec cylinders come in two different capacities: Model PDT-45 (4.5kg or 10lb) and Model PDT-90 (9.0kg or 20lb). They are supplied empty from the factory, with no agent inside.

Each cylinder is fitted with a valve (choice of either brass or nickel-plated) with a quarter-turn ball valve for connecting to the detection tube. Every cylinder valve is equipped with a pressure relief device (rupture disc) and fitted with a straight siphon tube. The cylinder valve, together with the detection tube, forms the heart of the PyroDeTec system.
