Dieselcraft Oil Centrifuges

WASTE VEGETABLE OIL

FREQUENTLY ASKED QUESTIONS

The centrifuge alone can not remove glycerin from vegetable oil.

Removing glycerin from vegetable oil can only be done by a chemical process. 

This process is known as "transesterfication" (trans-ester-fication). 

You must use a pre-mix of methanol and a catalyst such as sodium hydroxide or potassium hydroxide, measured precisely and blended with the oil for a determined period of time.  

The reaction that takes place will cause heavy glycerin to settle where it can be drained off. 

A centrifuge can then be used to remove large portion of the liter free glycerin that still remains suspended in the oil after the "transesterfication" process. 

Question: I'm running it from my truck on site.  Is there a DC motor solution?

            Answer)  Generally all DC/ 12volt motors are limited to 30 minute duty cycle by the nature of the motor. They get too hot to run. The use of a 115 volt motor with an inverter that will take the output of the vehicle alternator and turn it into 115 volts is recommended. We have been told but not confirmed that some electric motor types have problems starting on inverter power. We have had customers that have built mobile systems but none have given us all the details that we can pass on. I suggest using the Biodiesel info pop at:

Question:

I’m about to start a Biodiesel operation. I will be filtering 1000 gal of veg oil per month this will most likely grow to 5000 gals per month within the year. Would the OC-50 centrifuge be up to this since it would operate for 9.5 hrs to complete filtration? What product would you suggest for my application?

 Answer: 

The OC-50 is the best centrifuge for any application that has a small start up budget but needs the ability to grow in the future.

Oil must be heated to a temperature of 140-180 F. Oil also needs to be turned over three times on the average to assure cleanliness. This will all depend on the oil and how you pre-screen it. One pass is not realistic and 10 passes is over kill. Generally 2-5 passes does it. 

Here are some options.  

Project how many gallons per day is your goal in one year? 

By investing today in a pump and motor that can pump that projected number you then can budget and add centrifuges as you grow.  

Example 1: Buy a pump today that will move 8 Gallons per Minute/ 480 Gallons per Hour. Cost $1125 plus one centrifuge@ $499. Total $1624 

You can today run one centrifuge that will process 108 gallons per hour. So in 8 hours and one centrifuge you will be able to clean 288 gallons per day based on three passes through the centrifuge. 288 gallons per day will give you 6300 gallons per month. 

You then can add as many as four centrifuges as you grow. Price $499 each. 

With four centrifuges you can clean 432 Gallons per Hour. Based on that 432 GPH you could then in an 8 hour day clean 1100 gallons which translates into 24,200 gallons per month. 

Example2: Buy one centrifuge @ $499 and one matching pump and motor @$549. Total price $1048 and you then can process the same 288 gallons per day. As you grow you will need to add this same package for each increase of 288 gallons per day you want to process. 

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

The OC-50:

• Runs at approx 8,000 RPM at 90 PSI.
• It holds 20 ounces of solid and water contamination mix.
• It processes 1.8 gallons per minute
• Cost is $499
  • Includes mounting plate and control valve.

 The OC-200:

• Runs at 4,500 RPM at 90 PSI.
• It holds 84 ounces of solid and water contamination mix.
• It processes 5 gallons per minute
• Cost is $1550
  • Includes control valve only
    • Mounts are available

In both cases the centrifuge will remove water.

• The oil, either waist vegetable oil or motor oil, must be heated to a minimum of 140F. 180F if optimum and 205F 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 5.4 gallons per minute and with 25% more force that one OC-200 cleaning 5 gallons 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.
  • Dieselcraft offer this pump for $549
     
• The OC-200 requires a pump and motor that produces 5 gallons per minute at 100 PSI.
  • Dieselcraft offer a pump for this application that produces 8 gallons per minute for $1125.
  • You can take this pump and run the one OC-200 or  up to 4 each OC-50 centrifuges

FOR ENGINE APPLICATIONS

The Dieselcraft “Cyclone” Series Oil Centrifuge is a permanent, reusable by-pass oil filtration system for diesel engines.  Used in addition to a full flow filter, it keeps oil cleaner longer, reduces filter changes and extends oil life. 

The centrifuge cleans oil by generating a centrifugal force 2,000 times greater than gravity. Engine oil pressure spins the rotor at a rate over 6,000 rpm’s, separating the solid contaminants from the main oil supply and spinning them to an outer bowl, which is easily cleaned. Holds over 10 ounces of contamination.

Contaminant particles as small as 1/10^th of one micron are removed, eliminating the wear and tear on close tolerance metal parts.  The centrifuge’s proven soot removal technology keeps the extra soot from EGR engines out of the oil.

The centrifuge can handle maximum particle size of 500 

micron at the input. The centrifuge nozzles are .045 

inches/ 1.15 mm. However, for the safety of the pump, 

it is best if a suction filter of 100 micron is used.

This unit pictured below is for 2001 thru 2005 Chevy Duramax engines. Complete kit for easy installation on replacement oil filler tube.
