Item 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.
