TB110 hazardous area rated bulb and capillary temperature controller, single set-point temperature control, BriskHeat heat tracing controller, and 25°F to 325°F process maintenance thermostat are key uses for this industrial control device. It helps you manage heat in areas where safe, steady temperature control matters for equipment, materials, and workflows.

This controller is built for heat tracing, freeze protection, and process maintenance tasks. You can use it to help keep pipes, tanks, valves, and other heated systems within a set range. The single set-point design keeps operation simple, so your team can adjust and monitor heat without a complex control setup. The 304 stainless steel bulb and capillary provide remote sensing over a 10-foot length. This helps you place the sensing point where the process temperature needs to be read, while keeping the enclosure in a better service location. The design supports practical control in industrial spaces with limited access.

With a 22 amp rating up to 480VAC, this unit can handle many electric heating control jobs. Its SPDT contacts allow clean switching for compatible systems. The 6°F differential helps reduce rapid cycling while still giving you stable control for freeze protection, heating jackets, and process temperature maintenance. The NEMA 7 and 9 enclosure rating supports approved hazardous area use where dusts, gases, or vapors may be present. The controller displays both °F and °C, which helps mixed teams read settings fast. Average accuracy is ±5°F, with repeatability at 1% of the full range.

The TB110 controller is a strong fit for refineries, chemical plants, food processing lines, water treatment sites, and outdoor industrial systems. You can pair it with compatible heat trace cable, heating blankets, heated hoses, or drum heating systems when simple on/off temperature control is needed. Its bulb and capillary sensing style works well when electronic sensors are not the preferred choice. The 10-foot capillary gives you room to position the bulb at the heated surface or process point. The listed maximum exposure range of -40°F to 160°F helps guide safe enclosure placement.
