Detroit Radiant TP-264D Pressure Switch

The Detroit Radiant TP-264D Pressure Switch is a critical OEM safety component designed for Re-Verber-Ray low-intensity infrared tube heaters. As a normally open differential pressure switch, it monitors air flow and combustion pressure within the system, ensuring the blower is operating correctly before allowing the ignition sequence to proceed. This specific model features a factory-preset sensitivity and includes a hose and barb for a secure connection to the sensing port. Designed as a direct substitution for the PPS10069-2551 (TP-61D), the TP-264D is engineered for durability in high-cycle commercial and industrial environments.

This HVAC replacement part is compatible with a wide range of Re-Verber-Ray series, including HL2, DX2, XTS, DET, and DES models. Whether used in 175 MBH burner configurations or specific 65-75 MBH units, the Detroit Radiant TP-264D acts as a reliable safety interlock. By sensing the negative pressure generated by the vacuum pump or fan, it prevents the gas valve from energizing during unsafe venting conditions. For technicians performing maintenance or infrared heater repair, this genuine Re-Verber-Ray pressure switch ensures the equipment maintains factory-standard performance and safety compliance.

Key Benefits:

• Direct OEM Replacement: Seamlessly replaces legacy part numbers TP-61D and IS22020051F5170 without requiring mounting modifications.
• High Compatibility: Validated for use across multiple Re-Verber-Ray heater lines including the LS, RH, AG, and SV series.
• Reliable Safety Interlock: Prevents ignition and shuts down the system if combustion airflow is restricted or the blower fails.
• Industrial Grade Construction: Features a robust housing and high-sensitivity diaphragm designed for the temperature fluctuations of radiant heating systems.
• Complete Kit: Includes the necessary hose and barb fitting for immediate field installation.

Common Questions:

How do I know if my TP-264D pressure switch is failing?
If your tube heater fan runs but the igniter never glows, the pressure switch may not be closing. Check the vinyl tubing for cracks, moisture, or obstructions before replacing the switch.

Is the Detroit Radiant TP-264D adjustable?
No, this is a factory-set differential switch. Attempting to adjust the set point can lead to unsafe burner operation or frequent nuisance tripping.

Can I use this switch on a 175,000 BTU unit?
Yes, the TP-264D is the standard specification for high-output 175 MBH HL2 and DX2 series heaters, as well as specific 65-75 MBH HL3 and DX3 models.
