BriskHeat® TB4000 bulb and capillary temperature controllers are designed for general purpose use in outdoor or indoor environments to control temperatures on applications requiring automatic control.

  • Ideal for high wattage tank and hopper applications
  • Suitable for outdoor industrial use
  • Easily set your desired temperature
  • Bulb and capillary control
  • Three temperature range choices to fit your application


  • Set the dial for the desired temperature to be maintained. If the sensed temperature is below the set-point, power is applied to the heater and the indicator light next to the set-point dial is illuminated. After the set-point temperature is reached, the indicator light next to the set-point dial shuts off and heater power is removed. The control cycles are as necessary to maintain the desired temperature.
