Dual Hydrogen Control Panel (DHCP)
Environment One's Dual Hydrogen Control Panel (DHCP) was designed specifically for monitoring scavenging seal oil generators. The DHCP contains two independent analyzers that monitor the turbine-end seal drain enlargement, collector-end seal oil drain enlargement with both valving for manual or DCS operation for checking casing purity of the generator.
The DHCP has the ability to automatically increase the amount of hydrogen gas scoured from the generator.
The DHCP works with GE's Mark IV, Mark V and Mark VI control systems.
DHCP Features and Benefits
- Automatically increase the amount of hydrogen gas scoured from the generator
- Intrinsically safe design
- Digital displays/warnings/alarms
