Maxi-Frig for R12/R134A ?
 

Has anyone used Maxi-Frig? It sounds too good to be true?

Yet another brand name for the same old illegal, dangerous
hydrocarbon (isopropane/isobutane) blend.

Does it work? Yeah, it works.

Is it safe? The sellers say yes, but can't seem to provide enough
supporting data, despite 15 years of trying, to pass the refrigerant
safety tests ALL refrigerants are required to pass before they're legally
approved. The sellers claim it's due to politics and Big Refrigerant Inc's
desire to own the market. You decide.

Is it smart to use? No. Virtually no A/C service shop will *touch* a
system that has had a hydrocarbon refrigerant installed. Working on it
would contaminate their equipment and their stocks of reclaimed and
recycled refrigerant. Those few shops willing to work on such tainted
systems charge a great deal of money to get rid of the illegal
refrigerant, flush the system and install legal refrigerant.

Ask at www.aircondition.com, but since no information is given about
what the product is, I have great doubts. It may be like OZ-12, which
was nothing but a blend of propane and butane, something you definitely
don't want in a car.

Is. The "MX-12a" nomenclature gives it away.

The Maxi-Frig designation MX-12a is a dead giveaway. HC-12a, ES-12a
"EnviroSafe", etc. -- they're all the same illegal hydrocarbon blend.

What country are they illegal in??? Yeah, I thought so... Read up
on the stuff and see what you think. It is no more dangerous than
that large tank with gasoline that rides behind you when you are driving
your vehicle. That is my opinion...

The "large tank with gasoline that resides behind you" is subjected to
crashworthiness testing when the car was manufactured. Its in a
protected location, with various protections to prevent it from
spilling, rupturing, or bursting into flame. The AC condensor that is
the FIRST thing to break in a head-on collision is NOT crashworthiness
tested when filled with butane/propane blend. The blower motor inside
the car with the evaporator coil is not spark-arrested for use in an
environment where butane/propane might leak out.

Do I think cars with propane/butane refrignerant are rolling time-bombs?
Not really. But its foolish to pretend that they don't have a higher
risk of fire or explosion. The question I'd ask myself, is "why take ANY
risk when there are so many safe, non-flammable alternatives?"

The US for one. ANY flammable blend is illegal.

The EPA has made it illegal to use flammable refrigerants in motor
vehicle air conditioning systems. Each potential new refrigerant must be
tested according to the American Society of Testing Materials (ASTM)
E-681 testing method to determine flammability. In addition to testing
the refrigerant itself, if a blend contains a flammable component, the
EPA requires leak testing to ensure that the composition does not change
during a leak and become flammable.

http://www.epa.gov/ozone/snap/refrigerants/hc-12a.html

OZ-12 - unacceptable - 3/18/94 OZ Technology Flammable blend of
hydrocarbons; insufficient data to demonstrate safety.
R-176 - unacceptable - 3/18/94 Arctic Chill Contains CFC-12, which is
inappropriate in a CFC-12 substitute.
HC-12a - unacceptable - 6/13/95 OZ Technology Flammable blend of
hydrocarbons; insufficient data to demonstrate safety.
R-405A - unacceptable - 6/13/95 Greencool Contains a perfluorocarbon,
which has extremely high global warming potential and lifetime.

There has also not been any single refrigerant or blend that is a direct
drop-in for R-12 in automotive air conditioning systems.

The US.

The fuel system is specifically designed to store and transport flammable
fluid. The A/C system is not.
