We no longer offer the bowl heaters for the Racor filters - we had a failure rate of about 30%. That's one reason we developed the OverNighter - which don't fail.

The design for this multi-function heated filter housing took years to develop but even the first prototypes produced impressive results. The basic concept incorporates a coolant heated filter housing that uses a bath of coolant around an adequate supply of vegetable oil. Determining the correct size of the supply balanced two important criteria; making it large enough not to starve the engine of fuel during load demanding situations while at the same time, not making it so large that it would waste energy and heat. In the end, this balance resulted in a highly efficient design. Another consideration was to allow for an even heat to prevent temperature spikes within the fuel system.

Incorporating all system components to function in a single unit (multi-function filter housing) was also a main consideration in the design. Unlike most systems with all their needed add-ons, our goal was to include all of the necessary components in a single unit. Most existing kits use multiple separately mounted components which are needed to attempt to achieve the proper level of heat. This results in numerous gadget’s mounted in an already tight engine compartment. With all this extra apparatus under the hood, several things are going on; the fuel line ends up significantly longer and countless additional plumbing fixtures are needed. The resulting contraption can become nothing more than a large heat sink, and, in some cases it can actually loose the very heat you were trying to retain.

Instead of mounting separate components in numerous locations, the V.O. Tech system is an all-in-one design with a cleanable stainless steel filter in a coolant heated oil bath capable of ten (10) micron filtration. The filter has more surface area than some of the largest filters now used in this market. All solenoids are connected to a fuel control manifold (patent pending) which is attached to the filter housing with no fuel lines in between (except in extremely tight engine compartment applications where limited space requires the components to be separated). The multi-function fuel manifold distributes the fuel according to valve operation. It also includes:

A sight glass window on the return fuel side to allow for 1) monitoring fuel flow and 2) air in fuel diagnostics in both diesel and vegetable oil modes.
A vacuum/pressure access port on the feed side to allow for monitoring restrictions in the vegetable oil filter and in the diesel filter, depending on which mode the system is being operating in.

At the bottom of the filter housing is a regulated 10 Amp disc heater that will automatically shut down once it reaches 175 degrees (after the coolant heat has brought the oil up to a safe temperature to inject). The filter housing has a simple removable screw cap which allows easy top loader filter service. It also has a combination water drain/water sensor on the bottom which sends a signal to an LED panel letting you know if free water is indicated in the housing. This drain is very helpful during filter service and the sensor is highly sensitive to the detect the slightest levels of water or anti-freeze in fuel (in the unlikely event that cross contamination occurs).

An oil temperature sensor is also mounted in the housing. This sensor reads the actual oil temperature inside the filter housing to let you know precisely what the oil temperature is before you switch over. It is extremely important to understand that during warm-up, coolant temperature does not necessarily equal oil temperature; in fact, it usually does not. With the sensor mounted in the filter housing questions regarding these previously unknown temperatures are easily answered.

Another feature incorporated into the design of the filter housing is the ability to flush it out without back flushing the filter (back flushing the filter is undesirable because it sends filth back to the fuel tank). Soaking the filter in diesel after flush extends filter life because the diesel fuel helps dissolve any polymerization or wax crystals that may have formed on the element.

For example, in a situation where the driver forgets to flush, an alert tone will sound at engine shut down to provide a warning indicating that the oil has not been flushed out of the system. At that point, the driver should re-start the engine and flush.

System Operation
The engine is started using traditional petroleum based diesel. During this warm-up period the operator can monitor the diesel filter for restrictions using the vacuum/boost gauge. Prior to switchover, the operator can also monitor vegetable oil temperature at the filter housing.
Once vegetable oil reaches sufficient temperature the switch is put in the Veg. oil position (switchover to veg. mode). At this point, the oil temperature gauge is no longer monitoring the filter housing; instead, it will monitor the injection oil temperature at the IP or injector rail. One of the advanced capabilities of this system is that it allows for monitoring oil temperature in two locations (at the filter housing and at the IP). It is the only system with this dual temperature monitor feature. Because of this feature, it is the safest available and the only way to ensure all criteria are met.
After switchover, the vehicle is fueled by straight vegetable oil. During this phase the driver can watch the temperature gauge to see the IP temperature rise as the hot oil is pushed into injection. And, monitoring filter vacuum is easy with the vacuum/boost gauge.
At shutdown the three-way toggle switch is placed in flush mode. This will flush the veg. oil out of the system so it doesn’t solidify in the fuel system. It also prevents engine damaging coking and internal engine carbon buildup. During this phase, the oil temperature gauge can continue to be monitored as the IP temperature will drop as the cold diesel fuel passes the sensor. This temperature drop is an excellent indicator to let you know that fuels are switching. It also gives a clear indication of how long a basic flush takes for your particular vehicle. The amount of time required for a complete system flush depends on the particular application and varies widely from one vehicle to another. It is a function of fuel system type and flow rate and ranges from as short as four seconds to as long as two minutes.

Time to become inventive. If the cloud point is a problem in low temperatures, raise the damn thermometer! The nifty device above, although it looks like a form of body art (insert this into your piercing...), is a fuel filter pre-heater unit which I constructed, the purpose of which is to use engine coolant to warm (and hopefully homogenize) the fuel coming into the filter assembly. Here you see it in it's finished form, inside the intake of the fuel filter housing. You're looking at the bottom, where the spin-on filter attaches. The two hose fittings on top of the filter housing will go between the radiator vent and the expansion tank, ensuring a continuous flow of pretty danged hot coolant to transfer heat to the fuel. From what I've read, diesel engines run stronger and more economically with heated fuel anyway.

Hi Omar. I followed the V.O.Tech link you gave and went snooping around. Nice looking stuff, but I couldn't seem to find prices on anything. How do they expect to sell anything?

I'm guessing that the stuff is so expensive, they intentionally leave the price hidden so that once they get a shopper to phone in, they can talk them through the sticker shock. I may sound cynical, but that's all the advantage I can think of to be gained by not showing prices. I mean, I assume the motive wasn't to leave room for haggling over prices or something.

I just like the up front approach. This is like reverse telemarketing.

Some obervation I have made in my R&D on these
electrically heated filters(I guess it would apply to coolant heated ones too)... A lot of these are based on wrapping the filter. Just because the cannister is hot doesnt mean all the frozen oil is melted. I observed this in testing heating methods. When you wrap the cannister, the heat gradually works its way into the center of the filter-no surprise there.But you can have the outside toasty but still have frozen oil in the pleats and center. That doesnt mean it wont ever get liquid, just that it may take longer than you might think. I have been testing two super secret methods of thawing out a frozen trufilter cleanable filter. This filter is small, holds about 8-12 oz of fluid when cannister removed. I needed 150-250 watts of heat for slightly under 10 minutes to thaw out that little cannister completly. I also tested an internal heated element and got similar results Makes me wonder about the effectiveness of those less than 75 watt heaters used on much larger filters...

WVO Dry/Settle II
February 16, 2005 After a few months of not being able to filter frozen WVO we got our new WVO filtration system and settling tanks are online. We utilized the same filtration and pump from our earlier systems to pump into two 110 gallon conical tanks. We went ahead an increased the size of the system to get ready for our new 90 gallon reactor that would becoming online shortly to replace our 45 gallon reactor. The plan is to let the WVO settle for about two weeks and then drain the settled water. After the water is drained the WVO goes back into the pump system where it can be run through our filter bags or just drained back into 55 gallon drums. By painting the box black and facing the window panes south we are expecting a big solar gain and the end of our winter WVO freezing.
The problem we discovered with this design was thermal lag. The box would heat up during the day, but much of that heat would be lost at night. This was not a problem in the spring and summer months, but in the winter we knew we could not recover from extended cold days which would slow down our process of the water falling out.

Solar anyone???

hey- I was just gonna add my filter to this thread, but I see omar beat me to it. mine is the first fm-100, w/ the coolant wrap and 100 w heat spear inside it. I am very pleased w/ this setup so far, of course the coldest months are past us for the year.
the filter is a stanadyne fm-100 with a 5um element, and the lower wattage heater that they sell. the lower watt version has a higher temp cut off, but it is still set at 90*, i beleive.
but that is plenty for thawing, and preheating until the coolant heat kicks in, this will be fed w/ a HIH set up.

all in all, I got the head,heater,and 2 5um elements shipped for $105, which is a heck of a deal.

if you check out reliable's webpage, they have all the specs on the numerous different elements available for these units.

that new one from plantdrive looks nice.

mobetta could i bug you for some more info please.

1) are the prefilter screens able to be used with the pump option?
2) what about the water collection bowl.
3) is the pump able to replace lift pump on a 123 mb
4) what about the filter change indicator
5) can the purge option be used on the pump as well.

thanks, i value your opinion more than a salesman, thanks again george

Does anyone recognise that coolant heated filter head that Omar displayed on March 25th? (the one with the red Baldwin spin-on element) It looks very similar to the Frybrid Volkswagon coolant heated head. There is a difference though. There is a different top mount above the heat exchanger portion. On the Frybrid site, it doesn't seem to show where the hosebarbs bring fuel in and out of the head, but on Omars' photo you can clearly see the fittings. Stainless too!

I followed Omars link to e-bay, but the item is no longer displayed. If Frybrid and the guys on e-bay can get the Volkswagon heat exchanger heads, they must be commonly available. I wonder if the e-bay seller makes the mounting top himself or buys it somewhere?

I also like the new Plantdrive filter. The V.O. Tech filter is beautiful, but looks very expensive. Unfortunately they don't seem to show prices on their site. I wonder how much they actually are?
