Gas Station™
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 unit efficiency and generator performance can be maximized - and downtime minimized. The E/One Gas Station addresses each of these concerns and allows plant operators, together with E/One, to configure targeted solutions for original equipment supply and retrofit applications.
The E/One Gas Station is a modular approach that combines monitoring and control systems into a single, integrated platform, customized to meet specific site requirements and budget parameters. 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
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 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 throughout all phases of operation, with early warning of overheat monitoring. An ideal retrofit configuration in support of generator life extension. |
