The RPG-HC4 is a high performance gas regulator specifically developed for high capacity required by offshore firewater systems.
The RPG-HC4 controls a downstream gas pressure and is capable of supplying a large volume of gas in order to sustain a set pressure level in the recipient.
The regulator is used in active hydrophore systems for fire water offshore. The RPG-HC4 will maintain the given set pressure in the system while the hydrophore tank discharging water into the deluge system in the critical seconds before the firewater pumps is up running. This secures positive pressure in the entire pipenet and prevents pressure surges.
