Oil Centrifuges FAQs

OC-50 and OC-200 performance, differences and suggestions.

The OC-50:
Runs at approx 8,000 RPM at 90 PSI.
It holds 600grams of solid and water contamination mix.
It processes 7 litres per minute

The OC-200:
Runs at 4,500 RPM at 90 PSI.
It holds 2500grams of solid and water contamination mix.
It processes 19 litres per minute
Mounts are available at extra cost.

In both cases the centrifuge will remove water.
The oil, either waist vegetable oil or motor oil, must be heated to a minimum of 55C. 75C is optimum and 85C is maximum
The water will be held inside the rotor with the solids that are removed from the oil.
Some water will be removed as steam the higher you get the temperature.
A small amount of water may be “free water” in the rotor. If water is a real concern you must catch or divert the last 30 seconds of oil discharged from the centrifuge. This can be done with a valve or simply placing a bucket under the discharge at shut down. If you see no water in the bucket the water is trapped in the solids or is not an issue.

The OC-50 produces approximately 25% more centrifugal force than the OC-200.
So the issues is how much time do you want to run the centrifuge unattended to clean the oil and what is the volume of the oil you have to clean.
Multiple OC-50’s are more efficient that one OC-200 based on centrifugal force.
Based on dollars to spend you can buy three OC-50’s for the same dollars.
(You will clean 21 Litres per minute and with 25% more force that one OC-200 cleaning 19 Litres per minute)
You will have to clean or exchange rotors on the OC-50 ever one to three hours.
(The OC-200 can go six to eight hours with out cleaning in most cases.))

Motor consideration:

The OC-50 requires a gear pump and motor that will produce at least 2 gallons per minute at 100 PSI.
The OC-200 requires a pump and motor that produces 5 gallons per minute at 100 PSI.
(You can take this pump and run the one OC-200 or up to 4 each OC-50 centrifuges)
Pumps require 100um pre-strainer
240Vac Band Heaters with thermestat control.
