I was only speaking of the Ford Philco when they were making

refrigerators. Your


speaking total history which I don't really know about.



Turtle,

This isn't one of those REALLY old models that used the equivalant of
cyanide gas instead of freon, is it? Seems I recall reading somewhere
that there was a point in time when fridges were killing people if the
thing sprunk a leak.

Where do people come up with this crap. Old electric refrigerators used
ammonia and then they switched to freon. And what does equivalent of cyanide
gas mean? Either they used cyanide or they didn't. You really think anyone
ever put cyanide in a home product?

i don't know what your tring to say here but G/E Corp. in Refrigerators in the
late 1940's or early 1950's or there abouts made refrigerators with SO4 as the
refrigerant in it. My Father worked on them and I was the Kid helper. I do
remember working on one refrigerator on maginolia street where the SO4 charge
was let loose in the kitchen of a customer by accident . A tubing line broke
off and my father and I run for our live to the out doors. We got to re enter
the house in about 2 hours to finish.

The last SO4 refrigerator i seen was about 12 years ago when a fellow brought it
to you to try to fix it. I done away with the SO4 50 pound drum of gas we had
about 15 years ago. We had stainless steel guages and everything we had to work
on them with was stainless steel material or rubber hoses.

I don't remember anybody getting killed with the SO4 refrigerators but Carl
Harmon spent 3 days in the hospital for breathing a vapor he was hit with he
thought you put a regular tap on it for freon and not SO4 type tap. And No it
was not amonia type refigerator for amonia if spilled out. You walk away and no
problem but SO4 if you don't run your dead.

George they did make SO4 refrigerator to use in your home years ago for I've
worked on them. Now as to what the name is for SO4 for refrigerators is , you be
the judge for we called it SO or SO4 .

I was disputing the use of cyanide. Maybe what I
said wasn't too clear, so I'll say it a little
more forcefully. I suggest that no manufacture
would produce a refrigeration unit for home use
that uses cyanide. It just isn't conceivable that
the public would accept such a product, but all of
the A/C fluids were toxic or flammable before CFC
were introduced. Nonetheless cyanide is
certainly one of the compounds tried experimentally.

Sulfur dioxide along with ammonia, carbon dioxide
and methylene chloride were the main fluids until
cfc and some of these continued in commercial
applications. I'm surprised that any company was
manufacturing new machines for home use using
sulfur dioxide in the early 50's. Based on my
readings, most home appliance used freon at that
time, having taken over from ammonia refrigerators.

My father worked as a refrigerator repairman for
Sears a while before I was born. As near as I can
remember from his stories, everything that he
worked on was ammonia. We even had an old
refrigerator that he had converted from ammonia to
freon sometime around 1940. After a move, it sat
without running for many years but was used
continuously from around 1975 to 1990.

You were lucky, sulfur dioxide (btw it is SO2) is
nasty stuff.
