Recycled R12 - Storage Tips

Recycled R-12
Storage Tips

Here are some simple safety items to remember when you're storing recycled R-12 refrigerant:
^ Never try to refill a standard disposable 30 lb. tank with reclaimed refrigerant. Use only DOT approved refillable tanks provided by the recycling equipment manufacturers or suppliers.

^ Keep your tanks clearly marked: one for contaminated refrigerant, one for recycled. (most recovery/recycling equipment manufacturers supply labels for this purpose.)





^ If you need to transfer liquid refrigerant from one tank to another, keep in mind that refrigerant expands when it gets warm. So, never fill a tank to more than 80% capacity. The remaining 20% allows for expansion. (A tank filled bewond 80% call he dangerous! See the temperature chart and review the tank manufacturer's "transfer" instructions.)
