    "ecoFreeez is made of only the purest refined ingredients available today."

    What are those ingredients?

    Seems fishy to me. Wonder if it is just reclaimed 22 repackaged. Too many questions.

    It's not like they have SWAT teams on alert ready to actually enforce anything, but so far the EPA has only approved hydrocarbon refrigerants for small domestic and commercial refrigeration appliances...

    It is my understanding that if a refrigerant doesn't have SNAP approval for the application, it is technically illegal to replace R-22 with it.
    If more government is the answer, then it's a really stupid question.

    Never mind, They like to disguise the ingredients. after reviewing the msds, Propane? NO NO!
    Thanks guys, wishful thinking.

    Odor Threshold: None available Specific Gravity: 0.5066
    Coeff. Water/Oil Dist.: <1 Evaporation Rate: Rapid
    Freezing Point: -305F Boiling Point: -44.5F
    Vapor Density: (est.) 1.52 pH: N/A
    Vapor Pressure: (PSIG) 70 @ 110F
    SECTION 3 – FIRE OR EXPLOSION HAZARD
    Auto Ignition Temperature: 873F
    Flashpoint: Not Available Lower Flammable Limit (LEL): 2.15% Upper Flammable Limit (UEL): 9.60%
    Extinguish Media: If possible, stop flow of gas. Use water to cool fire-exposed tanks, surroundings and to protect personnel working on shut off. Water spray, dry powder, or carbon dioxide can be directed at flame area to reduce fire intensity. Do not extinguish flames unless leak can be stopped.
    Hazardous Combustion Products: Normal combustion forms carbon monoxide.
    Sensitivity to Static Discharge: Vapor may ignite if exposed to static discharge.
    Explosion Data: Sensitivity to impact. Mixture is not sensitive.
    Fire and Explosion Hazard: Flammable vapor may form if allowed to mix with air. Accumulation of gas is an ignition hazard. Vapors are heavier than air and may travel to an ignition source.
    SECTION 4 – INGREDIENTS
    Hazardous Ingredients % Cas Number LD50 P.E.L. ACGIH TLV UNITS
    Alkanes 100 n.ap. 800 ppm 800 ppm
    (Enviro-Safe™ Refrigerant contains a trade secret odor of 1% -5% unless otherwise noted.)

    Chemical Stability: This material is chemically stable.
    Conditions To Avoid: .Avoid sparks, open flame or any source of ignition.
    Incompatible Materials: Avoid contact with strong oxidizing agents such as chlorine, permanganates and dichromate’s. Decomposition Products: This product may produce carbon monoxide with a deficiency of oxygen.
    Hazardous Polymerization: will not occur.
    Polymerization To Avoid: Keep separate from oxidizing agents.

    Thumbs up ecofreeez EF-22a AWSOME

    Just dove in and tried it. The stuff is absolutely amaizing. I ordered a tank 30lbs equivalent. Key word here is EQUIVALENT. You actually get 12lbs net which goes as far as 30lbs of R22. To my surprise it truly does!!!. Used same guages same pressure points. Absolutely Amazing.
    Just as they said 1oz of EF-22a = 2.5oz of R22. Lower amps.
    A lot cheaper than R22
    Very happy

    What If?

    What if an unknowing tech attempts to leak check a system with this in it with an H-10, or even worse, a halyde torch.

    I haven't used one of those in over 30 years. I think I've been doing this too long.

    Will we ever see you post your own comments, or only when this product is mentioned?
