Detroit Radiant TP-55A Inducer Assembly

The Detroit Radiant TP-55A Inducer Assembly is a high-performance 120V replacement blower designed for the Re-Verber-Ray and Detroit Radiant heater lines. Engineered for precision draft induction, this 120V inducer motor ensures proper combustion air flow and exhaust venting for industrial-grade tube heaters. Direct compatibility includes the DR Series, DP Series, and specific HL Series models. Built for the rigors of commercial heating environments, the TP-55A manages internal static pressure to maintain efficient burn cycles. The assembly features a robust housing and high-temp lead wiring to withstand the heat cycles typical of overhead radiant systems. When troubleshooting radiant heater ignition failure or inducer vibration, this assembly restores factory-spec ventilation performance and ensures the pressure switch circuit closes reliably. Replacing a failing motor with this OEM-grade inducer prevents premature heat exchanger fatigue and optimizes fuel-to-air ratios for consistent thermal output.

Technical Performance Features

• Voltage Specification: Operates on a standard 120V, 60Hz circuit for seamless integration into existing control boards.
• Compatibility: Direct replacement for Detroit Radiant heater parts within the TP and DR series lineup.
• Combustion Efficiency: Maintains precise air-to-gas ratios to stabilize the burner flame and prevent soot accumulation.
• Quiet Operation: Precision-balanced blower wheel reduces vibration and mechanical noise during startup and operation.
• Direct Fit: Designed for an exact bolt-on installation, reducing labor time during field service calls.

Common Questions & Troubleshooting

What are the signs that my TP-55A inducer needs replacement?
If you notice high-pitched bearing noise, failure to close the vacuum pressure switch, or if the motor fails to spin up during the pre-purge cycle, the motor winding or bearings may be compromised.

Is the TP-55A compatible with 24V systems?
No, this is a 120V assembly. Always verify the voltage requirements at the control board before installation to avoid electrical damage.

Does this assembly include the gasket?
Standard field practice recommends inspecting the mounting gasket upon removal. If the previous seal is brittle or torn, a new high-temp gasket should be applied to prevent exhaust leaks.
