KOEHLER K43041 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.

High Temperature ‘Sequence IV’ Liquid Foam Test Bath 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 Borosilicate Glass bath jar. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Specifications Conforms to the specifications of: ASTM D6082 Temperature Control: Digital Setpoint and Displays °C/°F switchable Built-in Overtemperature Cut-off Protection Included Accessories Test Cylinders, 1000mL (2) Diffuser Stones, calibrated and certified (2) Air Delivery Tube Assemblies (2) Air Outlet Tube (2) Bath Jar (1) Support Rack (1) Rubber Stoppers (2) Acrylic Safety Shield, 18”
