Diesel Pre-Heat Module

Trombetta has developed a temperature dependent pre-heat module designed to provide optimum control of diesel engine glow plugs and air intake heating elements. The S500-B100 Series diesel pre-heat module has an ISO standard footprint and is sealed to IP 66/67 standards to protect against harsh environmental conditions such as moisture, vibration and extreme temperatures, the Menomonee Falls, Wis., manufacturer said.

When the ignition switch is turned to the run position, the S500-B100-02 module powers the glow plugs and/or air intake heating elements. This keeps them energized for a predetermined time based on the ambient temperature. At the same time, the module can activate a dashboard “wait” indicator light, which remains ‘on’ until the glow plug or air intake heater reaches the required temperature then turns ‘off,’ signaling the operator to turn the key to start the engine.

The company said the S500-B100- 02 modules are targeted toward for single-switch ignition systems, such as three- and four-cylinder diesel engines that require temperature compensation and an accurate wait time indication for the operator. The modules are configured to activate the engines glow plug or air intake heater elements from 3 to 30 seconds based on the ambient temperatures. In addition, Trombetta can customize the modules to meet specific customer requirements and the units incorporate industry-standard ISO Pin-Out configurations which are IP 66/67 rated in a potted nylon housing.
