What do you classify as 'bulk'?

My old firm used to get it in 13kg disposable cans; bear in mind thast you can also use it on old R12 fridge kit as well.

You can buy it from RPW in 12.5kg non-returnable or returnable cylinders. The product is also known as ISCEON 49. It is also available in a 1kg non-returnable can but unlesss 1kg is all you need then it is is much more cost effective to buy the 12.5kg cylinder as you will also need to buy a valve adaptor for the 1kg can.

Check with the manufacturers for their recommendations.

Its about 90% charge weight of the original as pint for pint the new refrigerant weighs less, charged as a liquid as its a blend. As Brian says, check out the refrigerant manufacturers website for their recommendations.

I've been told that Liquid charging can only be done through High service port in Automotive A/C system, my question is there's only one service port on Hermetic compressor,and I believe it's a low service port ,so how liquid charging can be operated ,I'm confused:eek:,please tell me how to do it,
thanks

It has to come out the bottle as a liquid but you can restrict the flow with the blue valve on your gauges, in effect using it as a hand expansoin valve, so that only gas enters the system.
If it is a really small system, to put the final bit of charge in i usually fill the yellow hose with liquid (15/20g) then shut the bottle, then open the blue valve on the gauges a bit, that way you don't put too much in at once. The final additions to the charge should be made once the system has reached its set temperature and is cycling on and off on the stat as normal. If you try to do it all in one go, most likely you will put too much in, least this is what i have done when rushing:o
Finally when done mark it with the refrigerant type and quantity added.

I have to ask, have you done any work on a refrigeration system or air conditioning in the past or is this your first try.

Depends on whether the bottle has a dip tube or not.
