Description
Reliable Nitrogen Automatic Pressure Maintenance Devices are designed to connect nitrogen cylinders to dry pipe and preaction systems. The NS-ASAM is designed to connect a primary and secondary cylinder or bank of cylinders to single or multiple systems, and provides automatic switchover between sources.
The NS-PaK is a self-contained unit for connection of a cylinder or bank of cylinders to a single system. The Nitrogen Regulator reduces cylinder pressure and can be connected to the Model A Pressure Maintenance Device on single or multiple systems. Each device includes a low-pressure switch to signal that the nitrogen source is depleting and needs service. High-pressure cylinders (not included) can typically be obtained from a local source.
