For Follow Up:

Normal Priority

Richard,

Thank you for the additional information about your reclamation 

equipment. 

That answers our question about the make and model number and the 

laboratory performing certification testing (UL). The second image also 

verifies that this device is certified "for use with equipment at medium, 

medium to high, and high pressure refrigerants per ARI 740." The label 

mentions R-12, R-134a, R-500, R-22, R-502, R-407C, R-407A, R-402A, and 

R-410. 

Do you know--is the pressure with HCR-188C in the design pressure range 

for the device (336 psig to 435 psig)?

I will check with Julius Banks and Dave Godwin to see if they have 

further 

questions.

Margaret:

Attached are the following images:

210 Recovery model 25200B Robinair 

216 serial# 50021 UL Certified

218 Oil separator used to remove oil from refrigerant.

219 Evap pump

221 10 cfm evap pump.

Better to take pictures, I had to get portable unit because I use it out 

in the field.

I reclaim the HCR188C in a twin valve 30 pound steel cylinder

1- for vapor

1- for liquid

Any questions please feel free to contact me.

Thank you for all your help.

Richard,

Our specialist in refrigerant recovery and recycling asked for the make

and model of your refrigerant recovery equipment. Has this equipment

been certified? If so, for which refrigerants, to what standard, and by

which independent laboratory?

Dear Margaret:

My intention for HCR188C is to be used in new refrigerators and new home

air conditioners units.To retrofit a refrigerator or AC home unit is

not feasible because of cost.

The normal home window unit 12000 BTU is around $200.00 and the

normal-sized refrigerator is approx $500.00. Whenever one fails, it is

cheaper to buy a new one and not fix it.

I guess I did not clarify this.

Most of the exposure of HCR188c would be at a factory when they charge

the new system.

If there is a failure or warranty, they would just discard it and the

store would replace it with a new one. The old one is scrapped. Scrap

yards just recycle the unit by removing the refrigerant and sell it as

propane for the barbecue grill. It would be easier to blend the

refrigerant from new hydrocarbons.

I have used a Robin air EPA-approved reclaimer for HCR188c which has an

oil-separator

which separates the compressor oil from HCR188C and recycles HCR188C

back into a canister. I found it much more effective using the recycled

refrigerant in a BBQ charcoal burner. It can be reused as a refrigerant

but my own personal feeling is that it is such a small amount and that

part of the blend might get lost in the process so I would rather have a

brand new blend in an air conditioner. Although I've used it over and

over many times, the barbecue grill was the best.

At Cortland, New York while testing my refrigerant at Intertek in

February of this year, I did ask Rob Hill about a reclaimer for

Hydrocarbon Refrigerant, All he told me was that there was no company

that he knows is doing it since the EPA has not approved it as an

Alternative Refrigerant.

I will ask him again in writing and get his response.

If this is part of a satisfactory explanation then I will get the rest

of the clarification to you

in a formal letter.

Thank you

Richard
