Air-conditioning gas

Hi All
On Sunday (31/05/20) I took part in the Zoom Jensen chat run by the North West owners group.
It was well worth the effort and an entertaining couple of hours with participant from Oz and even Essex.
During the various conversations the subject of air-conditioning came up and triggered in my memory (my memory is not good as it used to be thanks to the onset of age) an article I had read in a Jaguar magazine I acquired as a freeby with "Classic Cars" magazine three years ago.
The magazine is called "Classic Jaguar" and as I no longer own a Jag (used to have a 3.8 Mk2 mod) I have never bought another copy.
Anyhow I remembered reading an article about a restoration company called KWE Cars based in Berkshire and included in the article was an item about th restoration of air-conditioning with particular reference to the gas used.
As everyone knows the use of Freon gas in refrigerators and air conditioning is now banned as it is a global warming gas which attacks the ozone layer.
Here is a quote from the article:-
"....many cars of the era KWE covers were designed for R12 refrigerant, which has now been banned (same for Jensens). The common assumption is that cars must be converted to use R134a, as most modern cars do now. However it isn't as simple as just putting new gas in, and has considerable expense (see price of a new replacement air-conditioning unit for a Jensen). Chris is not convinced its a good idea anyway as many of the components are not designed to work with this less-efficient refrigerant."We use RS24, which is sometimes known as Isceon MO49 or R413. It is more expensive than R134a, but the actual cost per charge is only an extra £11>17.
RS24 is non ozone depleting and no components on the car need to be changed - though we always recommend changing the receiver dryer."
As you can see it could be worth looking into if your air-conditioning is not at its best, or working at all and you do not want to ge to the expense of over a £1000.00 to put in a new unit.
For more information KWE Cars is at

I hope this of help to you all, please keep well.
