Increasing efficiency, decreasing downtime of your electric power generator
E/One Gas Stations combine monitoring and control systems onto a single skid
The E/One Gas Station is a modular approach that combines monitoring and control systems onto a single skid, customized to meet specific power plant requirements and budgets.
Gas Station modules include:
- Main gas supply manifold and associated controls
- Gas purity monitoring
- Overheat monitoring
- Dew point monitoring
- Gas drying
- Partial discharge monitoring
- Seal oil system monitoring and control
- Customized annunciator panels
Power utilities and independent power producers are increasingly concerned with upfront capital expenditures and subsequent on-site engineering and installation costs. They also require accurate, real-time monitoring information so that generator efficiency and generator performance can be maximized — and downtime minimized. The E/One Gas Station addresses each of these concerns and allows power plant operators, together with E/One, to configure targeted solutions for original equipment supply and retrofit applications.
Contact E/One for detailed specifications of Gas Station configurations.

Gas Station Modules
|Generator Auxiliary System (GAS)
Used in conjunction with E/One's main gas supply manifold, provides local display of critical gas supply pressures, case, and differential pressure. May be supplied with digital displays in place of gages.
|Generator Gas Analyzer (GGA)
Provides continuous monitoring of hydrogen and purge gases for efficiency and safety.
|Generator Condition Monitor (GCM-X)
Provides early warning of generator hotspots, which can lead to catastrophic failure.
|Generator Gas Dryer (GGD)
Removes moisture and contaminants from generator cooling gas, reducing threats of corrosion and windage losses.
|Auxiliary Systems (AUX)
Customized to meet specific requirements and often include seal oil system monitoring and site-specific annunciator displays.
|GGA and GCM-X Dual-Module Gas Station
The popular two-module GGA/GCM-X Gas Station combines continuous gas purity monitoring of the Generator Gas Analyzer with early warning of overheat monitoring of the Generator Condition Monitor. The two-module Gas Station is an ideal retrofit configuration in support of generator life extension.
