The RCI Technologies Fuel Purifier

What is an RCI Technologies’ Purifier?

The RCI Technologies’ purifier is a simple one step unit that removes 100% of the free water and 95% to 98% of dust, dirt, and other normal and natural contaminates found in all diesel fuel. Even today’s “clean” diesel fuel will easily become contaminated during transportation and storage. Unlike all other products on the market, the RCI Technologies’ purifier performs this function without the use of a replaceable, changeable, or cleanable fi lter element, cartridge, or bowl. By removing contamination immediately before the fuel enters the engine’s filter system, the purifier delivers cleaner fuel, (virtually eliminating filter clogging) and therefore greatly extending maintenance intervals.

How does the RCI Technologies’ Purifier work?

RCI Diagram The RCI Technologies’ purifier is a unique product utilizing a three-stage purification process using two well-known fuel separation principles, centrifugal and coalescence. By using these two principles, water and other contaminates are separated from the fuel. This eliminates fuel fi lter clogging, related breakdowns, down time, and frequent filter replacements.

As the fuel enters the purifier, it flows downward in a circular movement through a internal baffle system entering the lower chamber of the purifier.

In the first stage of purification, the velocity of the fuel slows down considerably, allowing any free water droplets and other contaminates to maintain their mass and not emulsify with the fuel. These impurities accumulate and remain at the bottom of the purifier until purged.

In the second stage of purification, the fuel migrates through three perforated baffle plates to stop any particulates and attract, by way of coalescence, any water droplets still remaining.

In the final stage of purification, the fuel passes through our patented coalescence medium to assure that any small water droplets or particulates will be coalesced out of the fuel stream. Only the clean fuel rises to the top, providing a cleaner burning fuel for quicker ignition and better combustion. Consistent clean fuel helps to increase the engine’s dependability, power, and efficiency.

On the FP-50, FP-80, FP-400 and FP-700, a heating element is optional to preheat the fuel. This process helps liquefy the paraffin providing better lubrication for the entire fuel system including the pump and injectors. This heating element eliminates any wax or gelling problems.

The RCI Technologies’ purifier is simple to install, and provides The Permanent Solution to fuel system management and control. RCI Technologies also offers an optional water sensor kit, with an alarm signal, indicating purging is required.

Advantages of the RCI Technologies’ Purifier

There are many advantages and benefits to the owner and operator with the installation of an RCI Technologies’ purifier. These advantages include the following:

Engine benefits
  • Eliminates all water from the fuel system, thus avoiding time consuming break downs while preventing the formation of damaging sulfuric acid.
  • Removes all solid particles from the fuel system, including oxides, dirt, rubbish, and all other impurities with a density greater than that of the fuel itself.
  • Preheats the paraffin contained in all fuel, providing superior lubrication of the entire fuel system including the injector pump, injectors and cylinder walls. (Heater-optional part)
Economic benefits
  • Reduces down time.
  • Extends the life of the injection pump and the injectors.
  • Extends the life of the primary filter.
  • Protects and extends the life of the engine.
  • No internal or external parts requiring service or replacement
Ecological benefits
  • Increases the operating life of fuel filters.
  • The major component of fuel filters is paper. Use of an RCI Technologies’ purifier results in fewer trees being cut each year.
  • Reduction in land fill due to fewer fuel filter replacement.
  • Providing fuel that is free of water and suspended particulates is the first step in exhaust emissions control.
  • Significant improvement in exhaust emissions. Tests on the RCI Technologies’ purifier show that smoke emissions were reduced by 17.3%, carbon monoxide emissions by 10.4%, and nitrogen oxides by 5.9%.
Our technology in a nutshell

Modern diesel engines, especially the "Common-Rail" engines with their electronic fuel injection, require ultra clean and anhydrous fuel.

Their injection systems are highly sensitive to water and contamination. In many cases, the fuel is also used as coolant and pumped back into the tank/bunker again, considerably heated up. When cooling down again, water may be formed in the tank as a result of condensation.

And the combination of warmth and water means microorganisms!

When there is water and the temperatures are high, the microorganisms that can be found anywhere are able to reproduce rapidly with all its consequences. (See our leaflets and website.)

That is why it is extremely important to protect your valuable engine against the ultimate consequences that water and contaminants may cause.

The Knock-Down magnet is the next generation magnetic units of the direct flow type. The growth of microorganisms is permanently tackled, the system is maintenance-free and therefore has an unlimited life.

In turn, the RCI Purifier, a static separator, eliminates the killed bacteria, the free water and all contaminants larger than 5 micron through a unique, threefold, maintenance-free filter system.

The combination Knock-Down magnet/RCI Purifier increases the operating time of your filters and the life of fuel pumps and injectors.
