R600 Refrigerant.
Iwas wondering if anybody has used this refrigerant as i am only using R404a these days and have no experience of this refrigerant. I belive this refrigerant is an iso-butane based refrigerant and i would like to find any practical information on this refrigerant, such as handling,charging and reclaiming if possible.
Any information would be appreciated
cheers Tony.

Re: R600 Refrigerant.
Hi Tony
R600 is n-butane, R600a is isobutane, sold as Care 10. Boiling point is around -12C, most people use mineral oil. It's highly flammable so the usual precautions of earthing etc. for handling these kinds of materials. Recovery is still a bit of a grey area, but the latest seems to be that recovered refrigerant is to be treated as a controlled waste due to the oil which will be in it. On some sites where they have the facilities thye flare it off themselves, as unlike other refrigerants it doesn't need specialist incineration.
For lower temp use there is Care 30 (R12 pressures but has a glide) which is a blend, or Care 40 (propane, R290), higher pressure again.It's a lovely day to pump some gas

Re: R600 Refrigerant.
Hi johnny and des,
Thanks for the information you have given me. The reason that i was asking was that a friend of mine has a domestic refrigerator that was manufactured in germany that runs on this particular refrigerant and we were wondering if it was paractical to carry out a repair on the fridge or bin it .
cheers for your help,
Tony.

Re: R600 Refrigerant.
It's used in domestic fridges quite a bit, perhaps this is better asked in the domestic forum but I don't see why you couldn't do a repair the same way. Don't just get a can of butane from Camping Gaz Emporium, the refrigerant grade is a lot higher purity.

Re: R600 Refrigerant.
I don't agree completely with the last post. Hydrocarbons have been used commercially in recent years in much larger systems than domestics. For example the Sainsbury store on the millenium dome site runs entirely on hydrocarbon refrigerants.
I also know of several others.Tony

Re: R600 Refrigerant.
Are you speaking about R600 -butane
or R600a -isobutane
Anyhow "parfume" is much better. I'm with you US Iceman

Re: R600 Refrigerant.
Does anyone have experience reclaiming R-600? What reclaim machine do you use?

Re: R600 Refrigerant.
Graywolf,
Most refrigerators used R600a isobutane now a day. Flamable gas and have many risks to repair.
ignitation point are too low and in case of gas leak in confined/non ventilated places like kitchen or dining area then fire risk is there and dangeous because R600a is heavier than air. that's why most manufacturers used in small size refrigerators and non-servicible (one to one exchage) for refrigeration circuit. GWP very low, ODP is 0.
Don't reclaim or service. No point to take risk.

Re: R600 Refrigerant.
Hello,
I have a question. I heard that this refrigerant is not applicable with Aluminium tubes due to some kind of unwanted reaction. Is this claim true? Can someone help me about this problem.
thanks

Re: R600 Refrigerant.
Galvanic effect caused by Aluminium reacting with Copper and impact to the system is uncertain.
The strength of Aluminium pipes are uncertain compare to Copper pipes that had been in use for decades.
Nothing to do with R410A or R404 or R600a. Just under study stage, no one dare to take the risks.
Of course R600a is more worse because flamable gas and many risks involved.
