An integral heating and cooling unit is disclosed. The integral heating and cooling unit controls the temperature of a working fluid by heating or cooling the fluid either independently or in tandem. The integral heating and cooling unit includes a casing or outer housing, which defines a plenum. A heat exchanger pipe is attached to the outer housing and passes through the plenum. A plurality of heating elements connects to the outer housing and extends into the plenum. The heating elements heat the working fluid when they are powered and the working fluid passes through the plenum. The heat exchanger pipe extracts heat from the working fluid when a cooling fluid passes through the pipe and in heat transfer relation with the working fluid.

An integrated heater and controller assembly for monitoring and controlling the heating of a process in a reservoir is disclosed. The assembly includes a heater, a coupling adapter, a control unit, and a temperature sensor. The heater attaches to the reservoir and has a heating element extending into the process. The coupling adapter includes a first tubular portion and a second tubular portion. The first tubular portion attaches to the heater. The second tubular portion attaches to the control unit. The first tubular portion is rotatably attached to the second tubular portion. Wires from the control unit communicate through a pathway in the first and second tubular portions and connect to the heater. The control unit has control circuitry to control the power supplied through the wires to the heater. The heater may also have a thermowell that extends into the process. A thermowell adapter may be used to mount the temperature sensor inside the thermowell to measure and report the temperature of the process to the control unit.

Integrated heater and controller assembly

An adapter assembly for connecting a control unit to a heater. The control unit has wires that connect to terminals on the heater. The adapter assembly includes a first tubular body portion, a second tubular body portion and at least one locking bolt. The first tubular body portion is attached to the heater. The second tubular body portion is attached to the control unit. At least a portion of the first tubular body portion is retained inside the second tubular body portion. The locking bolt attaches the second tubular body portion to the first tubular body portion by inserting through a hole in the second tubular body portion. The present invention also includes an adapter assembly with the reverse attachments. Specifically, the first tubular body portion (retained inside the second tubular body portion) may be attached to the control unit instead of the heater. Similarly, the second tubular body portion may be attached to the heater instead of the control unit.
