Oxidation Stability Apparatus for Petroleum Testing Equipment

The Oxidation Stability Test Bath is designed to evaluate the oxidation stability of fuels and lubricants under controlled temperature and airflow conditions. Testing is generally performed at 95°C in the presence of oxygen or dry air. For inhibited mineral oils, the sample is reacted with oxygen in the presence of water and an iron-copper catalyst.

The apparatus consists of a constant-temperature liquid bath with solid-state temperature control, calibrated flowmeters, individual flow control valves, and a condenser water manifold. Each oxidation cell receives a controlled airflow of 3 L/h. The temperature controller provides rapid stabilization while minimizing overshoot. A redundant overtemperature protection circuit interrupts power if the bath exceeds the programmed temperature limit.

The bath features a double-wall insulated construction, copper immersion heaters, a circulation stirrer, and a stainless steel interior with a built-in support rack and overflow/drain arrangement.
