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 filter 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?
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 filter clogging, related breakdowns, down time, and frequent filter replacements.

As the fuel enters the purifier, it flows downward in a circular movement through an 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.
