How Do They Work:

Our dual coil design allows for a faster heat up and stabilized temperature. Watch the video below and see the proof for yourself.

The Results
Chart One

As can be seen in this graph, the DieselRx® glow plug peaks approximately 40°F higher during the initial in rush of current. The lower stabilized temperature translates to a longer lasting glow plug.

Chart Two

The competitor's plug requires 8 amperes more in the initial rush and 2 amperes more at the steady state of operation. The higher efficiency of the DieselRx® glow plug is attributed to our innovative manufacturing process and quality standards.

Glow Plug Controllers

DieselRx® supplies top quality glow plug controllers for various applications. Many often overlook the importance of these controllers and tend to only replace the glow plugs after failure. Sometimes it is a damaged controller that is the root cause of frequent glow plug failure.

Our Glow Plug Controllers offer:

  • Higher quality internal components
  • Better insulation
