KOEHLER K70200 Oxidation Stability Bath, RBOT / TFOUT

---

Test MethodThe RBOT procedure employs severe oxidation conditions to rapidly determine oxidation stability. Suitable for both new and in-service oils, the RBOT method is applicable to many types of petroleum oils. The sample is oxidized in the presence of water and a copper catalyst in a stainless steel pressure vessel under an initial pressure of 90psi (620kPa). Pressure inside the vessel is recorded electronically or mechanically while the vessel is rotated at 100rpm at constant temperature, and the amount of time required for a specified drop in pressure is the oxidation stability of the sample. A variation of the RBOT method is the “Thin Film Oxidation Uptake Test” (TFOUT) for gasoline automotive engine oils. Features and Benefits • Two, three and four-pressure vessel models • Conforming to ASTM requirements for RBOT and TFOUT testing

K70200 Oxidation Stability Bath, RBOT / TFOUT Constant temperature bath rotates oxidation pressure vessels at 100rpm at an angle of 30° in accordance with ASTM specifications. Includes drive system and oil bath with electronic solid state temperature control. Meets ASTM requirements for heat transfer capability and temperature control precision. A convenient carriage arrangement allows the oxidation vessels to be inserted quickly and securely in the drive system. A strong magnet holds the vessel in place while locating pins in the carriage engage the base of the vessel. PTFE guides support the pressure vessel stem for added stability. If the vessel becomes obstructed for any reason, the magnetic carriage releases it to prevent damage. A chain and sprocket drive system powered by a heavy duty capacitor start motor rotates the vessel carriages at 100rpm. Drive shafts ride on PTFE fluorocarbon bearings which provide extended service and are compatible with silicone heat transfer fluids and other types of bath oils. Bath temperature is controlled within ASTM specified limits by an electronic solid state controller with °C/°F switchable digital setpoint and display. Overtemperature protection is provided by a built-in limit control that automatically interrupts power to the bath when bath liquid temperature exceeds 16.7°C (30°F) above the temperature setting or 177°C (350°F). Power must then be manually restored by the operator after checking the cause of the problem. Pressure vessel carriage vanes circulate the bath oil during testing to ensure temperature uniformity, and an auxiliary stirrer can be operated between tests to prevent sludging of non-silicone bath oils. The bath interior is constructed of welded stainless steel and is fully insulated. A hinged section of the bath cover provides easy access to the vessel carriages. Vapor barriers in the cover close around the vessel stems to contain vapors from the hot bath medium. A chemical resistant polyurethane finish protects the bath exterior and control cabinet. Specifications Conforms to the specifications of: ASTM D2112, D2272, D4742; IP 229 Capacity: 2, 3 or 4 oxidation pressure vessels Maximum Temperature: 200°C (392°F) Control Stability: ±0.02°C (±0.04°F) Heater Range: 2 and 3-pressure vessel models: 0-2750W 4-pressure vessel models: 0-3750W Drive System: 100rpm positive drive transmission powered by a continuous duty 1/2hp ball bearing motor with built-in gear reducer Recommended Bath Medium: high temperature silicone heat transfer fluid (355-001-002 or 355-001-004)

Microprocessor PID control provides quick temperature stabilization without overshoot and the bath is protected by an overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Test cylinders are held securely in place by quick-locking cams in the bath cover assembly. A separate stainless steel support rack is provided to hold the test cylinders after removal from the bath. Cold bath (24°C) has built-in coils for circulating exit air from the high temperature test cylinders prior to passing to a volume meter, and a separate coil for circulating cooling water or refrigerant when the ambient temperature exceeds the test temperature. Supplied with rubber stoppers and glass air outlet tubes for each cylinder. Bath controls are enclosed in a finished steel base with chemical resistant polyurethane enamel finish. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information.

K43000-SFW Foaming Characteristics Software

Foaming Characteristics "test intelligent" software simplifies the testing process by providing sequential test prompts for assisting the operator with each step of the test procedure, and provides timing for both the foaming test and foam settling for up to 4 samples simultaneously. The sophisticated Windows®-based software package features an easy-to-navigate operation, a straightforward user interface, minimal draw on Windows® memory resources, automatic real-time data acquisition via RS232 connection, and a timer / stopwatch feature for general laboratory use. The active zoom, pan, and trace feature allows the ability to change axes and the magnification of any graph sector to view data in greater detail. The final test data is exported with graphs and test parameters (user name, sample name, sample ID, test type) either directly to Microsoft® Excel, in ASCII file format for use with LIMS or any other spreadsheet programs, or directly to a printer with a test report according to ISO guidelines. Test data is saved in a database format for determining test averages, standard deviations, and ASTM test repeatability. The software package requires no PC hardware installation and includes the software installation CD and computer connection cables. Computer Requirements PC Processor: Intel® Pentium II or similar (minimum) Processor Speed: 500 MHz or higher Operating System: Windows ® 98 SE, 2000, NT, ME, XP Memory (RAM): 64 Mb RAM (128 Mb RAM recommended) Hard Disk Space: 15 Mb free space (minimum) Communication Ports: two RS232 ports Other Software: Microsoft ® Excel (97 or above) For a complete demonstration of the Foaming Characteristics Software Package and its capabilities, please download a copy of the demo version (7.4MB file).
