Re: [Chrysler300] reciever drier/oli

[Tony Rinaldi <awrdoc@xxxxxxxxx>]

Hi Rob and all,

We have been using Freeze-12 which has no propane. Are you sure that
MaxiFrig 12a does not have propane in it. Did a search and came up with the
following:

__________________________________________

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.

__________________________________________

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

__________________________________________

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.


If you mouse around on the websites selling this stuff, you'll find them
talking about "legal 2nd-generation drop-in" refrigerant. This is a bit of
doublespeak. Here's how it works: It's illegal to replace R12 with
hydrocarbon refrigerants, but it's not illegal to replace R134a with
hydrocarbon refrigerants. A law against the latter was never written,
'cause there's no reason why anybody would ever replace R134a with
hydrocarbons. Unfortunately, that legal omission is being treated as a
loophole by those selling hydrocarbon refrigerants. The idea, they say, is
to convert your system over to R134a (which is legal), then replace the
R134a with hydrocarbons. Nudge nudge, not illegal, wink wink, elbow in the
ribs, and if you happen, wink wink, to forget the "change to R134a" step,
wink wink, why, that would be awful. Wink wink. Just terrible. Wink wink.

Dave,
 I have been running R-12 in my factory C A/C system.  I recently switched
to Maxi-Fridge 12a.  This is up to 30% more efficient and much cooler than
R-12 with no environmental hazards.  My A/C is cold (front and rear).  12
cans ran about $78 vs $45/can for R-12 with the requirement of having an A/C
license to purchase. No conversion equipment required.  I obtained it online
and it was delivered to my front door in 2 days!  300'ly,  ROB KERN

had a fellow tell me I should put a little a/c system oil in my new reciever
drier before installing it.

I'm hanging a new rebuilt A/C compressor on the F and EPR valve also. Gonna
use R-12

System has been down for 5 years or so and still had a charge in it. The old
compressor had locked up and burnt the clutch and bearing up.

Any comments??
