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 t esting (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, a nd 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 Sheppard USEPA/Stratosp heric Protection Division SNAP Program Tel. 202

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 t he 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 b urner. 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 an d 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 compan y 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
