Turbine Air Starters (ST Series)

Ingersoll Rand ST Series Turbine Air Starters

ProTech is an official Ingersoll Rand distributor and service centre in the Nordics, supplying engine starting solutions for diesel and gas engines in industry, marine, power generation and heavy equipment. 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 in demanding environments. With advanced single- and dual-stage turbine motors, the ST Series delivers high torque, smooth acceleration and long service life with virtually maintenance-free operation.

Turbine technology uses compressed air efficiently without air line lubrication, eliminating oil emissions and reducing environmental impact. This makes the ST Series ideal for clean applications, remote locations and extreme temperatures where electric starting systems or traditional vane starters are less suitable.

With a robust aluminium or ductile iron construction and an exceptional power-to-weight ratio, the ST Series is well suited for generators, marine propulsion, offshore rigs, mining equipment, gas compression and heavy industrial engines.

Why choose ST Series turbine air starters?

Lube-free operation – zero oil emissions and a cleaner workplace
High-efficiency turbine technology – optimal power output with lower air consumption
Extreme temperature operation – dependable performance in arctic cold or tropical heat
Durable design – withstands harsh environments and contaminated air supply
Low cost of ownership – long service intervals with minimal maintenance
