On the recovery machine:
 
I spoke to a Mr Jerry Wander at Inificon in East Syracuse New York about 
the Vortex Recovery machine. I have just purchased one and was inquiring 
about it being suitable for HCR188C recovery.  Mr Wander asked me about 
the pressure on HCR188C and pointed me to the ARI 740 1998. He said that 
HCR188C falls into a medium pressure category and the unit should be 
suitable for the recovery of my refrigerant. Once passed, all his company 
will do is submit to ARI about HCR188C  pressure and then the recovery 
machine will be rated. 
This will happen with every other one that is in the market at this time 
which are all EPA approved.
 
You can verify this by calling him at 315 4341100.
 
Any appliance which has any refrigerant in the system must be recovered 
before disposal. Any automobile a/c refrigerant must be recovered. This is 
an EPA ruling. As far as the recovery equipment goes, it will be certified 
when HCR188C is approved. This is what Mr Wander told me. He told me all 
recovery machines are made of high quality parts and can be used on many 
applications - the only difference is the pressure rating. Since HCR188C 
falls in medium pressure, he sees no problems even if it is hydrocarbon.
 
As far as recycling HCR188C, my personal opinion is with the small amount 
that is being used, it is not feasable. The charge rate is so small and 
some of the components are under 1% of the mixture and can be lost in the 
recycling process. When this happens the full effects of HCR188C will not 
be there yet it can still be used but in my opinion it will not be 100% 
effective.
 
As far as the EU goes, I see no merit in checking on what they do because 
in the US we already have a rule on all refrigerants being recovered even 
HCR188C with its low charge rate is no exception. I don't know if the EU 
has a recovery rule in effect but here in the US the rule applies to all 
refrigerants
 
Below you will find thew web site for the recovery machine in question and 
attached the ARI 740 1988
