RMI-25 Cooling System Treatment

RMI-25 Coolant Additive


With A Non-Hazardous Product
Saves You Money
No Downtime

RMI-25 restores the additive package to your antifreeze. RMI-25 is a liquid consisting of a pH Stabilizer for acid/alkaline balance, an Oxygen Scavenger to prevent cavitation, erosion and cylinder pitting. A Lubricant for seals, hoses and water pumps. A Cleaner that breaks down rust, scale and corrosive deposits. These deposits are changed from solids to a soft floating harmless gel-like material. These dissolved solids will not recombine or form blockages in the cooling system. After a period of time the dissolved solids will purge out of the system and into the coolant recovery tank. In the case of vehicles with coolant filters the dissolved materials will trap in the filter. In a couple weeks of driving a dirty system will be nearly clean. This cleaning action is continuous when engine is in operation. Once clean metal status is reached an organic barrier is then formed on the clean metal preventing further contamination. Water Conditioning is accomplished by a surfactant agent, improving heat transfer, making water a more efficient than coolant itself.

RMI-25 Protects Your Engine

The engines in heavy-duty trucks and other industrial equipment generate enough heat to melt down the engine block and related parts. If an engine's cooling system cannot dissipate that heat because of corrosion or deposit build-up, serious damage can be done to internal engine parts. Repairing that damage costs you money — both in expensive repairs and in lost revenues from downtime.

RMI-25 is a low-cost, effective safeguard against cooling system failure. It cleans while you drive; inhibits rust;, cavitation erosion, electrolysis and pitting lubricates water pump seals and thermostats; and improves cooling. RMI-25 should be at work always in every water-cooled engine.




Remove 'em All the Easy Way!!


Just 1/16 inch of mineral deposit on 1 inch cast iron is equivalent to 4 1/2 inches of cast iron, reducing heat dissipation by 40 percent.

Corrosion deposits of any kind raise the engine as much as 700 degrees, causing hot spots and loss of cooling efficiency.

RMI-25 cleans your engine cooling system's metal surfaces, then protects against cavitation erosion, electrolysis, pitting and further corrosion. RMI-25 promotes cooler operating and higher efficiency — and it does it while you drive, with no labor costs.

Power Flush — While You Drive

RMI-25 and your water pump make an unparalleled combination for cleaning your entire cooling system.

Water Pump

Vehicle water pumps circulate from 2,500 to 9,000 gallons of water per hour, depending on the size or make of your vehicle. By just adding RMI-25 to your radiator, your water pump becomes a powerful cleaner, circulating thousands of gallons of cleaning solution through your engine cooling system while you drive.

And this automatic Power Flush requires:

  • NO draining and flushing
  • NO downtime, no shoptime, no labor costs
  • NO loss of antifreeze/coolant
  • NO 30-to-40 minutes engine run time
  • NO harm to skin or eyes or to the environment
  • NO coolant gel problems

Just pour some in your radiator and drive away.

Antifreeze/Coolant is Only Partial Protection

Everyone knows an engine needs water and antifreeze/coolant to protect it fro freezing and boil-over.

But worn out antifreeze/coolant can actually damage an engine even though a hydrometer shows it has plenty of protection left against freeze-up and boil-over.

Antifreeze requires changing only because the inhibitors against rust and corrosion dissipate, the "freeze-up" protection doesn't wear out.

RMI-25 extends the life of expensive antifreeze by replacing the inhibitors — and you still are protected against freeze-up. At the same time, RMI-25 gives you all the other protection against cavitation erosion, electrolysis and pitting, as well as lubricating water pump seals and stabilizing pH.

Treat yourself to savings three ways with RMI-25:

  • Save on the cost of new antifreeze!
  • Save on the cost of hazardous waste disposal!
  • Save 80 percent on water filter replacement!

CLEANS - radiators, engine blocks, heater cores, hoses...the complete system

INHIBITS - rust, build-up of mineral deposits, cavitation erosion, electrolysis and pitting

LUBRICATES - thermostats, water pump seals and heater controls

CONDITIONS - improves heat transfer
