The panel coking apparatus to determine the tendencies of finished oils from coke when in contact with surfaces at elevated temperatures. It is designed to perform Test Standard 791 method 3462.

The unit is supplied with PID temperature indicating controllers for regulating the temperature of the test panel oil in the sump and air. It is equipped with a variable drive motor, digital speed display and air flow regulator system.

The optional Cyclic timing system allows for alternate splash/bake cycles to allow oil bake for a period of time on the hot panel without the addition of fresh lubricants. The optional sulphur dioxide gas system allows for the introduction of a corrosive acidic atmosphere thus increasing the severity of the evaluation. Because of the versatility of this test machine to simulate different test conditions, it provides an economical method of evaluating coking tendencies of lubricants prior to performing expensive engine deposit tests.
