GT-400 Turbo-Electric Generator

Reliable Power from Available Gas Flow

The GT-400 uses only the flow of natural gas as well as other gases to generate up to 400 watts of DC power in remote locations. Imagine having a reliable system that provides power for applications such as telecommunications, SCADA, process control, battery charging, cathodic protections and navigational lights. The unit can be used anywhere there is a pressure differential in natural gas pipelines, at the well head, in gas lift systems or with pipelines.

The generator provides power as long as gas is flowing. No longer are you at the mercy of solar panels that can fail to provide the required power because of snow, clouds or theft. The unit is an excellent way to provide practical power for remote areas where power is nonexistent or cost prohibitive. Remote gas and offshore wells benefit greatly from this dependable generator.

Dependable

The generator integrates the turbo-flywheel and alternator into one self-contained unit making it extremely reliable. The GT-400 generator has no power takeoff shaft, no seals to wear out and only one moving part.

A small amount of gas is diverted from a higher pressure gas source into the generator. As the gas enters into the chamber, it expands across the edge of the rotor-flywheel causing it to spin around the stationary stator. The permanent magnets mounted on the inside of the rotor-flywheel excite the windings generating electricity. The expanded gas is then returned to the system on the low pressure side. Without any surface-to-surface contact the turbo-flywheel gives years of dependable, maintenance-free uninterrupted service.

The unit is designed to withstand the harshest conditions. Its distinctive design allows moisture and particulate to pass through without effecting its operation. The entire unit is electroless nickel plated inside and out to withstand 1000 hour salt spray specifications. The alternator is encapsulated in epoxy making it impervious to sulfur contaminated gas. High precision ceramic ball bearings are designed to run in the worst conditions, protected by a channeling system to keep moisture and particulate away from them. Finally the exhaust ports are situated at the bottom of the inside chamber to insure moisture does not build up and can easily pass out of the unit with the exhaust gas.

Real-Time Communications and Control

The generator output electronics come enabled with 4 to 20 mA and RS-485 communications that provide real-time monitoring of the unit and batteries.

• RS-485 communications provide complete system monitoring including battery charging sequence, battery voltage, VAC coming from the GT-400 alternator, VDC to batteries or equipment, rotor flywheel RPM and more. It also allows for two-way communications so power output can be adjusted or a hot switch-over can be undertaken.
• 4 to 20 mA–provides battery voltage and rotor-flywheel RPM monitoring.
