120 Volt ELECTRICALLY HEATED centrifuge with pre-heater section, and a 15 minute timer.
Manufacturer: Robinson Manufacturing Company
Centrifuge features include: A circular design offering a high-efficiency unit that meets or exceeds the RCF requirements of API and ASTM. A rheostat control with an “off” position for a slow, smooth start and speed control. A pre-heater section located in the front of the centrifuge. Space saving design because a separate heater is not required. Lid designed with hole in the center so that the centrifuge RPM’s can be checked with a hand held tachometer with the centrifuge lid closed. Three independent electrical circuit design. One circuit operates the motor that spins the samples. A second circuit, controlled by an “on-off” switch and thermostat, heats the centrifuge bowl. When the sample is placed in the centrifuge at 140°F, the preset thermostat prevents the sample temperature from dropping below 135°F as specified by API and ASTM. The third circuit is for the pre-heater section, which is like a separate two-place electrical heater built into the centrifuge. It is operated by a high-off-low”switch and controlled by the operator. Depending upon the oil sample’s starting temperature, it raises the temperature of two samples to 140°F in minutes. 15 minute timer. 120 VAC, 60 Hz, 1 phase. Weight 65 lbs., 22” x 20” x 11-1/2”.
