Features

  • Wells are used where it is desired that the control operates from the temperature of a liquid in a closed system
  • The bulb of the control can be removed from an immersion well in the tank wall without draining the boiler tank
  • The packing nut can be used with any of the remote bulb types listed
  • Packing nuts permit closer control than wells because the bulb is directly immersed in the liquid
