Starting Power For Industrial Gas Turbines.

The 56 series easily takes your engine up through light off, delivering up to 150 HP of cranking power at 150 psig (10 BAR) inlet pressure. Power output is matched to each manufacturer's starting requirements to achieve the most efficient start-cycle. And the 56 Series is so powerful that in certain applications it develops adequate starting power while using less air, allowing you to reduce your air system requirements… and your costs.

Reduce Maintenance And Eliminate Exhaust Concerns.

Because there is no contact between the turbine elements in the TDI vane-less design, adding lubricants to the drive air is unnecessary. With nothing added to the drive air, on oily fugitive with emissions regulations compared to vane-type motors. No expensive air lubrication system to install and maintain… no messy and hazardous starter exhausts… no lubrication system to fail.

Robust Design For Reliable, Dependable Operation.

Reliability and safety are a result of the 56 Series' simple design and fewer parts. The overall strength is a result of quality components. Comprised entirely of metals- like a billet aluminum rotor and nozzles carved from steel- there are no fragile cast turbine elements or composite plastic parts. The open resistant to erosion and tolerant of contaminants that would clog or destroy other starters.

Efficient Single Planetary Gear.

To Match the starter RPM to the start-cycle of the engine, TDI uses an efficient single planetary gear reducer. Complex sets of compound gears are less efficient, requiring the rest of the system to work harder to make up for the power lost in the gear train. And in the event that your starter should ever fail, replacing the planetary gear train is much simpler operation than rebuilding a compound gear set. Which can take hours, at much greater expense.

Superior Clutch Design For Any Application:

Unlike other clutch mechanisms that rely on just a few contact points, the heavy duty overrunning sprag clutch distributes the torque load evenly to 22 points. This upgrade is the best choice for windmilling applications or to economically replace the pneumatic jaw-type clutch found on older gas turbine engine designs.

Flexible Options For A Variety of Situations.

The long start cycle of a gas turbine requires that critical components receive adequate lubrication. To reduce maintenance and prevent premature wear during windmilling, optional ports allow pressurized lubrication to guarantee sufficient oil supply and lubrication. The heavy-duty gearbox housing is rotatable to six different positions to allow different inlet positions while various exhaust outlets are available to adapt the starter to any application.
