RefTec’s Stand up Lite Evac™ (Dorin) Recovery/ Recycle/Reclaim system provides efficient and safe recovery of most high pressure refrigerants. Make sure you have a recovery tank with a minimum 3/4″ male flare vapor port and a minimum 3/4″ male flare liquid port, or larger ports if possible. This tank or series of tanks must be able to hold the entire refrigerant charge at 80% full and also must be pressure rated for the specific refrigerant being recovered.
