Thread: Regas with Hychill -30

so, Hychill is a legal, readily available alternative?

From what I have found it is.
Lots of people running it with no problems. Lower head pressures especially on hot days and with lower vent temps as well.Easier on the hoses and compressor seals.
Also more environmentally friendly than either R12 or R134a.
Buy a bottle from Bursons. There is one near Dave at the Industrial estate and another at Noosa.
One can get a 9kg bottle or a little top up can.

If hychill is a hydrocarbon refrigerant, yes it is legal but not readily available. People get scared about myths put out by refrigerant manufacturers like Dupont.

People don't worry about 90kg of LPG behind the seat in a taxi but worry about less than 500gms of hydrocarbon refrigerant in a sealed a/c system.

I have about 5kg of Care 30 another hydrocarbon refrigerant on my front porch, but need to change the York compresson on the '85 to use it (or recharge it.)

Problem is that I no longer speak to my oxygen thief brother to get him to do the job.

Don't you still need to fit a new drier before you change over from R12? Thats what we did when we changed my '85 over in the 1990s.

Did you measure the fill or just charge direct from the can by the pressures?

Forgot to mention that. Yes new receiver/drier fitted also.
I must mention this had already been converted to that inferior R134a but even though the PAG oil is in it . It is still compatible.
Have not gassed it yet as about to leave for town. Do it tomorrow.
I bought a digital charging scale on Ebay so will weigh in the charge.
Never done that before as I usually just go by the bubbles in the sight glass but as these systems need so little of this I will weigh it.

.. You will always get some, um, interesting/entertaining responses when discussing the Great R134a/BANG-GAS comparison... especially when you chuck in 134a hazards (Testicular cancer) vs Vested Interests, and enviromentally friendly propane...

Even more rabid than..... For/Against 'Flu vaccinations.

The Classic's system was (under...) built for the more efficiant R12, and unless the evap/condensor was enlarged when they were forced to go to 134a, you're short-changing yourself by re-gassing with the same.

Hydrocarbon refrigerants are more efficient than R12, though the differance is not, AFAIK, huge. - happy to be illuminated.
-But certainly almost any 'bang-gas' is better than 134a. Even straight propane.

Not only are peak pressures lower, the larger hydrocarbon molecule does'nt escape through hoses etc as easily as 134a. Very relevant when dealing with 20+ year old English motor-carriages...

We converted our freezer room and fleet of freezer trucks from CFC refrigerants to hydrocarbon refrigerants and we were getting up to five degrees lower temperatures. Being a larger molecule we also found we lost less gas from the systems.

In my '85 RRc the a/c went from reasonable to very efficient. I suspect Defender owners would find changing over their system would make the rather poor Defender (not puma) a/c into a reasonably effective a/c.

Most importantly hydrocarbon refrigerants are naturally occuring molecules with negligible "Global Warming Potential" while the CFC replacements like 134a have hundreds or thousands of times the Global Warming Potential, frequently remaining in the atmosphere for years without breaking down.

PLEASE! Make sure you label which type of muck sorry refrigerant you have used.I have turned down jobs that don't have service stickers or labels rather than risk poisoning my recovery gear and having to dispose of mixed gasses. And the fines for releasing 134a would put my family on the street.

But I agree with all the comments below, big company's control the worlds economy's like it or not , followed by cowardly politicians.

R134a is,was banned in Europe and to be phased out here by 2017 .Replaced by HFO1234yf which was better for the environment but is 6% less efficient than 134a, but they found it had a problem, it was flammable. Funny that . 134a won't burn at 500deg C but the oil burns at 200degC.
Chlorine from R12 has a 130 year life span in the ozone layer , so at the time 134a was a big improvement as it only has a 16 year lifespan as a greenhouse gas.

LPG refrigerants may work well in some situations but I don't fancy my fridge or freezer in the house using it. What would happen to the sealed compressor during an electrical burnout, one way to clean out the fridge! Glad we don't live near a supermarket. Horses for courses I suppose.

Cheers Steve

PS At zero psi R12 boils at -29.7 R134a. - 26.6 and hychill 30 -37.8
