What is a TDI Starter Motor?
A TDI starter motor is an air-powered engine starter manufactured by Tech Development Inc. (TDI). Unlike electric starters, TDI air starters use compressed air to rotate the engine and initiate combustion. This design offers superior reliability, especially in remote or hazardous environments where electric systems may fail.
TDI starters are frequently used on large diesel engines found in compressors, generators, trucks, marine vessels, and mining equipment.
Benefits of TDI Air Starters
1. Built for Harsh Conditions
TDI starter motors perform exceptionally well in dust, moisture, and high-heat environments. They’re designed to start engines reliably even after long idle periods.
2. No Batteries Required
Because they use compressed air, TDI air starters eliminate the need for large starter batteries—reducing maintenance costs and improving safety.
3. Compact and Lightweight
These units are lighter than traditional electric or hydraulic starters, making installation easier and reducing stress on engine mounts.
4. Long Life, Low Maintenance
TDI starter motors have fewer moving parts and are built to last. With proper servicing, they deliver a long operating life and consistent starts.
5. Explosion-Proof Options
TDI starters are available in ATEX-certified explosion-proof configurations, making them suitable for oil & gas or other hazardous applications.
