Thermostats may be mounted inside a terminal enclosure or remote mounted (separate from the heater assembly). If using a remote mounted thermostat, be sure to order sufficient capillary tube length to permit installation. Thermostats regulate temperature in non-critical applications. They sense temperature, within a preset range and cycle heaters on and off to maintain the set point.
Wells are used to protect the bulb from corrosion or for mechanical support. Each well is furnished with a brass stuffing box to hold the capillary in place after installation. To order, specify catalog number and thermostat type.
Screw Plug connectors (stuffing boxes) are used to make a liquid-tight connection where the bulb goes through a tank wall. If the wall is thick enough, it may be drilled and tapped to receive the stuffing box thread. Otherwise, a coupling must be provided.
