Robinson Centrifuge features include:
1. A circular design offering a high-efficiency unit that meets or exceeds the RCF requirements of API and ASTM.
2. A rheostat control with an "off" position for a slow, smooth start and speed control.
3. A pre-heater section located in the front of the centrifuge. Space saving design because a separate heater is not required.
4. 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.
5. Three independent electrical circuits design.
A. One circuit operates the motor that spins the samples.
B. 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 degrees F, the preset thermostat prevents the sample temperature from dropping below 135 degrees F as specified by API and ASTM.
C. 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 the two samples to 140 degrees F in minutes.
