KI-43041 Foaming Characteristics Apparatus, Sequence IV |
| Test Method Foaming of lubricating oils in applications involving turbulence, high speed gearing or high volume pumping can cause inadequate lubrication, cavitation, overflow and premature oxidation. The sample is blown with a controlled volume of air at different specified temperatures, including a newer high temperature test at 150°C. The resultant foam is measured at the end of each aeration period and at different intervals afterward. In the high temperature test, the amount of time required for the foam to collapse to “0” after the aeration period is also measured. Features and Benefits • Dual-twin models for standard foaming characteristics tests • High temperature liquid baths for ‘Sequence IV’ tests • Automatic time sequence models for both tests • Custom configurations for specialized applications |

| KI-43041 Foaming Characteristics Apparatus, Sequence IV For two tests at 150°C with a flow rate of 200mL/min in accordance with ASTM D6082 specifications. Consists of a constant temperature bath with 1000mL test cylinders, certified diffusers, air delivery tubes and flowmeters. 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. Quick response copper immersion heaters provide efficient high temperature operation, and a stirrer unit provides complete circulation for temperature uniformity of better than ±1°F (±0.5°C). Locking cams hold the test cylinders in a vertical position, and a separate rack is provided to hold the cylinders after removal from the bath. For operator safety, an acrylic heat shield surrounds the Pyrex™ bath jar. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your PSSC representative for information. Custom Configurations In addition to the standard configurations described, PSSC liquid-bath foaming characteristics test equipment can be ordered in the following custom configurations: • Dual-Twin 24°C/D892-150°C/D6082 • Dual-Twin 93.5°C/D892-150°C/D6082 • Single-Bath model for ASTM D892 (for 24°C and 93.5°C tests) Custom models have the same operating features and characteristics as the standard models and each bath is equipped with the necessary air flow and control accessories required to perform the applicable test method. Contact your PSSC representative for ordering information and pricing.
