As the title says. I am looking for information about a refrigerant reclaimer. The product will be used in a classroom environment. I started teaching a high school HVAC CTE program three years ago. I have many projects based around R-22 refrigerant as it is a very good refrigerant for beginners. With the rising cost, I would like to reclaim, and recycle our R-22. Anyone have experience with what I would like to do. I would only use the machine with R-22 alone. I presented the idea to my principal and got the goat head. All I need now is a clue!!!
