Whether it’s a pump operating to keep a community’s drinking water clean and safe, or an air compressor operating a sandblaster, GE takes pride in offering reliable, robust gas turbines that can be used for a variety of mechanical drive applications.


Air Compressors

Factories the world over depend on compressed air to operate industrial processes as well as a wide variety of pneumatic tools, including drills, wrenches, grinders and sand blasters. As a power source, compressed air is relatively safe, energy efficient and environmentally friendly. Compressors, often driven by turbines such as those manufactured by GE, compress the air that powers these processes and tools.



How It Works

The turbine-driven compressor pulls air in, compresses it, and pushes it into a storage tank to a maximum allowable level. When a tool is switched on, air in the tank is released to power it.

The compressor must continually replenish the air in the tank without overfilling it—which requires the compressor and engine to adjust their operating levels continually.

With variable speed capability and a “wide turndown” range, a gas turbine can operate more efficiently at reduced load levels than an electric motor which lacks such flexibility.

Engine-driven air compressors operate reliably where the electrical supply is non-existent or unreliable.

Blowers are used in a wide range of processes that are integral to mining, the manufacturing, petrochemical and food processing industries and utility operation. These processes, which require large flows of air or gases, include ventilation, dust collection, drying, heat treatment and testing processes. Aeroderivative gas turbines are often used to power blowers used in waste treatment plant operations.  



Chillers are the heart of the systems that supply air conditioning for buildings and refrigeration needs for industrial and commercial applications. Chillers driven by GE’s aeroderivative gas turbines can be used in almost any application requiring chilled water. They are well suited to larger-tonnage cooling loads in areas with medium-to-high electric rates and have the potential to capture waste heat from the engine or turbine for other process needs.

How It Works


In a vapor compression chiller, the compressor pumps the refrigerant gas through the system. When engine or turbine driven compressors are used, the system has the added benefit of a heat recovery option which can be used in a variety of other processes that reduce energy costs.

Operating turbine-driven chillers during peak demand times can help reduce overall energy costs by reducing electricity use when costs are highest.

Because gas turbines have a wider “turndown” range, they can operate chillers efficiently at partial load during low-demand times.

Pumps are used in a wide variety of mission-critical applications where dependable performance can literally be a matter of life and death – from providing municipal drinking water to flood control and wastewater treatment, irrigating farmland, and pumping crude oil and a wide variety of liquids in vital industrial processes. For many of these applications, the pumps are driven by aeroderivative gas turbines such as those manufactured by GE.

How It Works

Turbine-driven pumps may operate continuously in municipal water and sewage treatment utilities, oil production sites and various industrial processes, or they may be needed only intermittently for irrigation or in emergencies, such as for flood control after a major storm.

With a variable speed capability and wide turndown range, a gas engine can vary a pump’s flow rate to meet changing operating needs.

GE’s Waukesha gas engines and aeroderivative gas turbines provide dependable pumping power independent of electrical power sources and are a reliable back-up for electric pumps.
