Abstract
A parts washer (10) including a receptacle (12) positioned on a reservoir for cleaning liquid having a drain opening (36) and a module (40) which engages a portion of the reservoir in the cleaning liquid for adjusting the temperature of the cleaning liquid and circulating the cleaning liquid into the receptacle (12). The module includes a heating element (74), a sensor (75) and pump (78).
An enclosure (82) houses a temperature controller (100) which displays the temperature of the cleaning liquid and low level condition. A bridge (114) thermally links the heating element to the sensor so that the sensor normally generates a signal representative of the temperature of the cleaning fluid unless the level of the cleaning fluid is disposed below the sensor.
