Elliott YR steam turbines are rugged and reliable pieces of precision turbomachinery. These masterpieces of Elliott engineering and craftsmanship serve thousands of customers continuously, day and night, under conditions ranging from humid tropical heat and rainfall to freezing icy tundra and snowfall. Many YRs have been performing for decades – day after day, year after year.
Elliott YR turbines are found driving pumps, compressors, fans, blowers, generators, sugar mill tandems, cane shredders, paper machine lineshafts, and in many other applications. Elliott YR steam turbine models are standardized and components are stocked, resulting in shorter leadtimes and faster turnarounds.

Single-valve, single-stage Elliott YR turbines have a worldwide reputation for the highest quality, reliability and adaptability to serve a wide range of requirements. Available in multiple frame sizes and ratings up to 5,400 hp (4,027 kW), Elliott YR turbines are cost-effective in their design and perform under varying conditions.

For improved steam consumption, Elliott designed the Multi-YR (MYR) steam turbine product line. The MYR design combines the reliability and parts interchangeability of our popular YR turbine with the power and efficiency of multistage turbines. The MYR produces more power without additional steam, and can be installed in many areas where single-stage steam turbines currently are operating. Elliott MYR turbines are available up to 14,000 hp (10,440 kW).

Engineering expertise, rugged design, and precision manufacturing come together for years of service in Elliott YR steam turbines. These powerful workhorses provide exceptional value and performance in a broad range of mechanical and power generation applications, around the clock and around the globe.

Effective, efficient turbine packages begin with a thorough understanding of the site specifications, from the pad to the placement of panels and other components. Elliott Group is a global leader in the design, manufacture and packaging of rotating equipment, lubrication systems, and sealing and fueling systems for turbomachinery. Our packages are engineered to reduce installation and maintenance costs by consolidating the equipment footprint, minimizing on-site alignment, and tightly integrating all connections.
A standard steam turbine package can include:
♦ Elliott YR steam turbine
♦ Gearbox
♦ Baseplate
♦ Coupling
♦ Electrical system
♦ Lubrication & control-oil consoles
♦ Gland vacuum, sealing and leak-off systems

Tri-Sen control systems are standard offerings with all Elliott compressors and steam turbines. The Elliott Tri-Sen Turbomachinery Controls Alliance provides a single point of contact for the full scope of rotating equipment expertise and advanced turbomachinery controls. Users can turn to one source to address turbomachinery component questions, software issues, and retrofit application concerns.
Through its alliance with Tri-Sen, Elliott provides machinery protection systems such as the TetraSentry hydraulic trip systems as standard offerings with new Elliott turbines and retrofit applications.
The Tri-Sen 310SV regulates speed and provides cascade control for process variables such as suction/discharge pressure or suction flow. The self-contained unit has manual push-button turbine controls, user-friendly software applications, and a 24-volt DC or optional 120/140-volt AC power supply
The Tri-Sen TS300 is a selfpowered digital controller providing automatic startup and speed control for singlevalve general-purpose steam turbines driving a mechanical load.
The Tri-Sen TetraSentry is a dual parallel-redundant hydraulic trip block that’s on-line testable and on-line repairable. The TetraSentry is connected to the hydraulic trip header in parallel with the turbine trip valve. During a trip action, the high capacity solenoid valves dump the trip header fluid to the reservoir faster than the supply orifice can refill it.

Elliott offers comprehensive service, support and training for all types of turbomachinery regardless of the original manufacturer. Our global service network provides installation, maintenance, repair, overhauls, parts, rerates, modifications, and training. Our service teams have the experience and expertise to keep equipment performance high and maintenance costs low.

The Elliott YR Site Service program maintains Elliott YR turbines in North America’s Gulf Coast region. Based in Elliott’s Houston service center, fully stocked repair units are dispatched to handle common services such as standard inspections and replacement of worn or damaged parts. The site service team can also transport a turbine to an Elliott service center for more extensive overhauls and repairs.
