The Evolution of Antifreeze Problem: 1.Engines need cooling 2.Water freezes during winter 3.Summer boil over 4.Cooling system corrosion 5.Inhibitor Depletion/ Maintenance Solution: Radiator with water Add Methanol to the radiator Ethylene Glycol Corrosion Inhibitors Change antifreeze, add SCAs (H/D) or use Extended Life Coolants

Antifreeze / Coolant Inhibitors-(5%) Glycol-(47.5%) Glycol Provides Boil-Over And Freeze Point Protection Water-(47.5%) Water Transfers Heat Inhibitors Protect Metals From Rust And Corrosion

100 0 Ethylene Glycol Concentration, Wt % 33% Glycol = Freezing Protection -20°C Temperature, °C Temperature, °F Max. Protection at Eutectic, -68°C Freeze Protection Typically - Ethylene Glycol + Water

Chemical Definitions Two Inhibitor Classes: Organic and Inorganic Organic Compounds- Chemicals which contain carbon atoms Inorganic Compounds- Chemical Compounds which do not contain carbon atoms

Silicate, Borate, Nitrate, Phosphate, Nitrite Fast Film Forming--Short Lived, Drop-out concerns Requires Addition of Supplemental Coolant Additive (SCA) when used in Heavy Duty Applications Silicate, Borate, Nitrite Fast Film Forming– Short Lived, Fewer Drop-out Concerns SCA Pre-Charged for Heavy-Duty Applications Coolant Technology Definitions Conventional: Inorganic Obsolete Fully Formulated: Inorganic DINISHING IN USE The Old Technology

THE PROBLEM: Fully Formulated Coolants Poor Coolant Or Poor Maintenance Contributes To More Than 40% Of All Heavy Duty Engine Failures

Fully Formulated Coolant/SCA Systems Shaded Area Represents Desired Glycol Range Of 40% to 60%. Glycol & Inhibitor Frequency Distribution

Glycol Concentrations To little Glycol the inhibitor levels are too low for protection in Conventional Coolants To Much Glycol leads to: –Over Heating – Formation of Acids High Acid concentration leads to corrosion Part failures

Daylight Plate Calibration Screw Focus Adjustment Main Prism Assembly Rubber Grip Eyepiece Step 1: Place 2 To 3 Drops Of Coolant Under The Daylight Plate. After 30 Seconds, Go To Step 2. Step 2: Looking Through The Eyepiece, Read Freeze Point For EG Or PG Base Coolant. Refractometer Best Practice for Freeze Point Adjustment

Fully Formulated Coolant/SCA Systems Shaded Area Represents Desired SCA Range Of 1.0 to 1.5 Units.

Why Is Maintaining SCA Levels Such A Problem? Why Is Maintaining SCA Levels Such A Problem? Inorganic Inhibitors Deplete Topping Off With Conventional Antifreeze Dilutes SCA Levels Topping Off With Water Dilutes SCA Levels The addition of too many SCA’s Max Min Ideal Over Treated Under Treated

Heavy-Duty Coolant Solutions

The Solution Recommended Best Practice Extended Life Coolants

Organic Acids, in Combination with one or more Conventional Inhibitors Fast and Slow Film Forming– Longer lasting than Conventional, Shorter lasting than OAT. Potential Drop-out Issues Organic Acids- No Silicates, Phosphates, Nitrates, or Borates Slower Film Forming—Longer lasting, No Drop-out concerns Coolant Technology Definitions Organic Acid Technology: Organic BEST Hybrid Organic Acid Technology (HOAT): Organic + Inorganic Better Current Technology

Global Evolution of Heavy-Duty Coolant Conventional Fully Formulated Extended Life Fully Formulated

Why Use Extended Life Coolants Superior inhibitor Performance –More Robust Inhibitors with Stands Higher Dilution –Slow Inhibitor Depletion –Improved Component Life –Improved Heat Transfer –Excellent Rust & Corrosion Protection –Excellent Hot Surface Protection

Slow Inhibitor Depletion Corrosion Inhibitor Depletion Rates Organic Inhibitors Deplete at a Much Slower Rate Than Inorganic Inhibitors

Improved Component Life Wet Sleeve Liner Protection A Sleeve Inserted In Diesel Engine Blocks To: Improve Heat Transfer Improve Serviceability Of Heavy Duty Engines One of the most common and costly cooling system repairs is the perforation of wet sleeve cylinder liners.

What Causes Cavitation Or Wet Sleeve Liner Cavitation? When the piston moves down it creates force on the Thrust and Anti Thrust side. This moves the Liner out and it snaps back creating an Implosion of bubbles.

What Is Causes Cavitation Or Wet Sleeve Liner Cavitation? Thrust on Liner In Untreated Systems, Imploding Bubbles Bore Through The Steel Liners

Preventing Wet Sleeve Liner Cavitation In Treated Systems, Imploding Bubbles Are Blocked By Inhibitors Inorganic inhibitors are destroyed in this process and must be replaced (Nitrite Depletion) Organic Inhibitors are not used up in this process

Improved Component Life No Silicates to plate out on surfaces No Phosphates to drop out and form Scale No borates which can be aggressive to Aluminum

Improved Heat Transfer No Silicates to Form a Heat Barrier No Phosphates to help in the formation of Scale another Heat Barrier

Heat Transfer Rate (at 2 gpm Flow Rate) 31 8 % Difference

Excellent Rust & Corrosion and Hot Surface Protection Carboxylate corrosion protection mechanism provides superior protection in high heat and coolant dilution situations

Water is Clear & Ethylene Glycol is Clear. Coolants Can Be Dyed Any Color. All Coolant Are Compatible – However Performance Is Impacted !! Conventional Coolants & Some ELC = Conventional Coolant ELC + More Than 25% Conventional Coolant = Conventional Coolant Treat Both Above As Conventional Coolant OK If You Treat ELC With More Than 25% Dilution With Water Or Conventional Coolants As ELC You Could Have A FAILURE. Color, Compatibility, Or Mixing

ELC Are Long Chain Hydrocarbons - Soaps - They Will Clean The System Up! Changing Or Mixing Old Conventional Systems With ELC Can Uncover Leaks & Create Premature Water Pump Failure. We Recommend Maintaining The Same Technology Which Is In The Vehicle. ELC Conventional

Conventional Systems Extended Life Coolant Conversion From Conventional Systems to Extended Life Coolant Maintain vehicles on Fully Formulated until sold –Continue to add SCA’a –Could use ELC as top up Maintain all new vehicles on ELC

Conventional Systems Extended Life Coolant Conversion From Conventional Systems to Extended Life Coolant Flush and Fill –Flush with water –Remove Charged SCA filter –Replace with Blank Filter –Drain all water –Fill with Extended Life Coolant 50/50 –Adjust Freeze Point if needed –Identify with new Product Sticker

Maintaining The Cooling System 1. Use only ELC 50/50 Pre-Diluted coolant when topping-off the cooling system. 2. If Extended Life Coolant is not available, top-off the cooling system with water. If freeze protection is not needed then Adjust freeze point when Concentrate ELC when available. 3. Maintain between a 45% to 60% coolant and a 55% to 40% water mix 4. Do not add Supplemental Coolant Additives (SCAs) to the cooling system or use chemically charged filters. 5. After conversion, You are good to go One Million Miles

Water Pump Failure –Check your coolant by holding a sample in a clear vessel up to the light. –If you see floating particles Change your Coolant

Why Extended Life Coolants Saves you Money $$$$$$$$$$$$$Saves you Money $$$$$$$$$$$$$ –Eliminates the Cost of SCA’s –Reduces down time for Maintenance –25% Dilution with out loss of performance
