Seems like a good time to bring this back up into view... especially since I accused Diesel Giant of being like Redfox....

A lot of people have read this thread... But it has been a year since it was on the front page.... perhaps some people will appreciate that some of the questions being posed now have had good discussions in the past...

Hot Shot, R-414B Is a great product......
Performance

OVER R-12

R-414B system pressures mirror R-12 operating pressures.

High and low side pressures will typically be the same to 5% higher than R-12, while providing 8% better performance. This means that slightly better cooling and quicker temperature drop will be obtained using HOT SHOT.

OVER R-134a

The most common complaint with R-134a in mobile systems, whether O.E. or converted, is the very poor temperature differential (TD) in high ambient temperatures of only 20 degrees while operating at exceptionally high pressures. For example, many automobiles using R-134a, operating with a return air temperature of 90 degrees only achieve a duct temperature of approximately 70 degrees. This problem becomes much more critical at even higher ambient conditions.

As ambient temperatures increase the head pressures also increase, often to the point where the high pressure cut-out disengages the compressor clutch, cycling begins to occur more frequently and system performance is even further reduced. This problem becomes more evident during periods of extended idle at high ambient temperatures.

R-414B will provide 20% better performance while operating near R-12 pressures. This means a much faster cool down and much higher temperature differential. For example, that same vehicle operating with a 90 degree return air temperature can now obtain as much as a 40 to 44 degree duct temperature at idle RPM and even lower temperatures at cruise RPM.

REMEMBER! No retrofitting or oil changing is necessary when replacing R-134a with R-414B.



Safety Classification

HOT SHOT maintains a UL classification of A1/A1. Completely NONTOXIC and NONFLAMMABLE as blended, and NONTOXIC and NONFLAMMABLE in worst case fractionation.

Re Hotshot ...

Probably ought to read this site carefully first...

It is a blend..... and the fact that the EPA allows it does not say that it does things like carry oil around the system well... just that it does not violate their chemistry requirements...

But the biggest problem with any blend .... finding a shop that will work on your system....

This is important information for new owners.

I use Freeze 12 exclusively and dont use R-12 anymore. I get better performance with it, colder temps and lower pressure. I have done LOTS of Freeze 12 conversions for myself and customers and have NEVER had a failure or complaint with it.

When you get near 30 degrees at the vent, who can complain.

Who? I understood part but not all of your message. Please expound on it.

I will answer and expound both... but need to do a search...

Huhh??

Too many riddles, plain English please.

Gary F,
First, I ASSUME that you know that FREEZE12 is 80 Percent 134a ?

Second, DIESEL GIANT is a DEALER.... and SELLS FREEZE12...

Third, I suspect once you see my reference to an EPA site you assume the reference is to following the ECO laws ( and don't go read it ).. when most of the time it is to show a reference having to do with things like using BLENDS like FREEZE12 and then trying to find a shop which will service it when you need it....
A couple of years ago we had the same kind of activity out of REDFOX trying to sell DURACOOL.

People still post saying they are thinking about using FREEZE12 or some other supposed ' R-12 ' drop in replacement... like there is an easy shortcut to doing things correctly...

The refrigerant oil carrying question is very important to people using the Delco compressors.. I don't want anyone to choose FREEZE12 or ANY other blend without FAIR WARNING... to do their research before making their decision.. and since the EPA and Aircondition.com have done nice writeups I give those as references.

The higher operating pressure are also a factor .... but it is easier to visualize a lack of good lubrication causing failure down the road.
If you read about BLACK DEATH on the AC forums... you understand that it often takes a year for complete failure to occur... this is one part of the equation which gets left out of DIESEL GIANTS claims about FREEZE12 working so well.... if he DID have failures a year later do you think he would post with a mea culpa ? LOL

My definition of FAIR WARNING when dealing with someone who is willing FOR ECONOMIC purposes to make misleading statements is to try to make the warnings appear on the same page each time the misleading/incomplete items are posted.

Leather,

Why do you feel the need to constantly attack me personally? If you dont like the product I use then so be it, but I would like to ask you to maintain a professionalism that the board members here deserve.

I will be happy to debate you on the issues, but leave out the other stuff.

Yes if I had a failure with one then I would post it, so stop attacking my character. No I am not mad at you.

Again keep on the subject not the messenger.

I feel free to attack your dishonesty ...
You are a dealer trying to SELL FREEZE12 by regularly posting partial and /or misleading answers to people's questions..
The forum rules say DEALERS are not welcome here... I don't know why you are are still around.

Guys really, can't we agree to disagree at this point? Lots of points have been made but not many new ones.

"Good judgement comes from experience. Experience comes from bad judgement."

listen, look, .........and duck.

You're making a very bad argument here.

Lots of things are illegal. Speeding is one of which we are probably all guilty. But what's the penalty? Is it accidentially a lower penalty than driving while drunk? Or could that be intentional?

You get popped for speeding, and in most cases, you're on your way with a ticket that you can simply mail to the proper court.

Let's say that your neighbor sees you pass him at a high speed on the highway, and calls the cops. Will they come to your house and give you a ticket? I don't think so.

Let's say that you do improper conversions on air-conditioners on the side, and you neighbor notices, gets irate at the traffic, and calls the EPA. Will they come to your house and give you a ticket? They'll come to your house, but the ticket is something like 25 grand, and your nosy neighbor gets a cut.

Do you see the difference?

I have been curious about this too. I would expect to pay for the advertisement, don't you?

Dealers on forums do tend to compromise the integrity of the site. Look at the biodiesel site for an example.

Someone said that Freeze 12 has a component that you have to be licensed to buy. Is it legal to sell freeze 12 to people who are not licensed?
