Detroit Radiant TP-50A Hot Surface Ignitor

The Detroit Radiant TP-50A Hot Surface Ignitor is an ignition component designed to produce the heat required for starting combustion in tube heating equipment. It converts electrical energy into a high-temperature surface that initiates fuel ignition when the heating sequence begins. As part of HVAC systems, it connects with the ignition circuit and aligns with the burner assembly to support controlled startup. Its heating element is positioned within the combustion area, allowing the equipment to establish the required flame source while maintaining the intended sequence between electrical controls and heating components.
