Turbine Air Starters (ST Series)
Ingersoll Rand ST Series Turbine Air Starters
ProTech is an official Ingersoll Rand partner, delivering professional engine starting solutions for diesel and gas engines across the industrial, marine, power generation, and heavy equipment sectors.
Ingersoll Rand ST Series turbine air starters combine high starting efficiency, lube-free operation, and field-proven reliability for heavy-duty engines where dependable starting is critical.

ST Series turbine air starters are engineered for reliable, high-performance starting of diesel and gas engines operating in demanding environments.
Featuring advanced single- and dual-stage turbine motors, the ST Series delivers high torque output, smooth acceleration, and long service life with virtually maintenance-free operation.
Turbine technology utilizes compressed air efficiently without requiring air line lubrication, eliminating oil emissions and reducing environmental impact.
This makes the ST Series an ideal choice for clean applications, remote locations, and extreme temperature operations where electric starting systems or traditional vane starters are less suitable.
With a robust aluminum or ductile iron construction and an exceptional power-to-weight ratio, the ST Series is perfectly suited for
generators, marine propulsion, offshore rigs, mining equipment, gas compression, and heavy industrial engines.
