TDI (Tech Development Inc.)

56 Series Turbine Air Starters

TDI TurboStart 56 series air starters are specifically designed for gas turbine engines. The TDI 56 series costs significantly less than most competitive products and boasts a simple, efficient design. These starters use a unique 22-point sprag clutch, which is more reliable than the typical three-point clutch.

Torque range: 55 to 520 lb-ft (74 to 705 Nm)

Typical applications: Gas turbine engines for electrical power generation, industrial drives, and marine propulsion

T100 Turbine Air Starters

As with all TDI TurboTwin series starters, T100 air starters feature a maintenance-free design and contain no plastic parts inside. Long cranking cycles and contaminated air have almost no effect on T100 series starters. Their heavy duty construction is designed for your most critical applications.

Torque range: 70 to 480 lb-ft (94 to 650 Nm)

Typical applications: Diesel and gas engines up to 300 liters such as Caterpillar 3412 and G3500 and 3600 series, Cooper Superior 825 series, EMD 567, and Waukesha 9390

T25 Turbine Air Starter

TDI’s T25 and T20 turbine air starters are constructed from durable, high quality, corrosion resistant materials. Standard and low pressure versions are available to suit your application. Both starters feature an integrated relay valve, which simplifies installation and keeps costs down. Click here for more information on T25 Turbine Air Starters.

Torque range: 40 to 135 lb-ft (54 to 183 Nm)

Typical applications: Diesel and gas engines up to 15 liters such as Ford 460, Cummins 5.9, John Deere 4045, and Continental TM27.

T30 Turbine Air Starters

Available in pre-engaged and inertia-engaged models, the T30 generates up to 25% more stall torque than other starters in its class. Its highly efficient twin-turbine motor design gives you more cranking power with less air for faster starts. Unlike starters that require a mechanical automatic trip valve (ATV), the T30 uses aerodynamics to control motor speed, giving you total control over the start cycle.

Torque range: 24 to 135 lb-ft (32 to 183 Nm)

Typical applications: Diesel and gas engines up to 20 liters such as Cummins 6BT5.9

T50 Turbine Air Starters

TDI T50 pre-engaged and inertia-engaged air starters are versatile, mid-size options designed for a wide variety of engines. The T50 offers the most power and torque per unit of air and is the lightest air starter in its class, weighing as little as 34 lb. Click here for more information on T50 Turbine Air Starters.

Torque range: 80 to 240 lb-ft (108 to 325 Nm)

Typical applications: Diesel and gas engines up to 80 liters such as Caterpillar 3500 series, Cummins KTA50 and QSK45, and Detroit Diesel 16V4000

TurboFlow Air Regulators

The TDI TurboFlow air regulator minimizes the pressure drop to the starter “in a dynamic manner” under high flow conditions. That’s how the high Cv factor on the TurboFlow makes available more useable air pressure in the tank. This translates to greater air flow delivered to the air starter motor, even at low pressures, and more starts on a fixed air volume.

Operating range: 50 to 580 psig (3.5 to 40 BAR)

TurboGuard Smart Starters

TDI’s TurboGuard Smart Starter provides the protection you need against hydrolock engine damage. Hydrolock occurs when an engine is started with coolant in a cylinder. TurboGuard detects the presence of fluids or other obstructions in the cylinders during the start sequence and automatically shuts down the starting process before damage occurs.

Typical applications: workboats and marine engines, engines with long periods between starts, engines with remote starts

TurboStartTwo Turbine Air Starters

The TDI TurboStartTwo is an Integral Start System that includes 1) a powerful air motor, 2) built-in controls with pre-programmed safeguard logic, 3) a flow-match relay valve, 4) an electric solenoid, 5) an integral muffler, 6) both pilot air control lines/fittings, 7) a simple plug-in interface to your engine control. It even has an emergency manual bypass provision, allowing you to start just on air if need be. Click here for more information on TurboStartTwo Turbine Air Starters.

Torque range: Up to 325 lb-ft (440 Nm)

Typical applications: Engines from 20-150 liters such as Caterpillar C32 and Wärtsilä W200

TurboTwister Turbine Air Starters

TDI’s TurboTwister air starter is pound-for-pound the most powerful air starter in the industry. It delivers more power per unit of air than the TurboTwin design while having fewer moving parts. This is TDI’s most rugged, reliable, and versatile starter, allowing it to cover a broad range of engines and decreasing your inventory. Click here for more information on TurboTwister Turbine Air Starters.

Torque range: 102 to 340 lb-ft (136 to 461 Nm)

Typical applications: Engines up to 150 liters

TurboValve Air or Control Valves

TDI’s TurboValve is a versatile, pilot-operated starting air or control relay valve used for the installation of TurboTwin air starters. Its high flow capacity reduces pressure drop through the valve, providing for a broad range of applications.

Direct replacement for Sealco Models 10900, 11900, 14900, 110250 and Ingersol Rand SRV125 and SRV150 relay valves.
