Ultimate Oxygenator Kit
This kit is for the ‘serious homebrewer’ who wants to control, and know, how much Oxygen they are injecting into the wort. The kit consists of the following:
1. A “refillable” 20 CF O2 cylinder. Has 20 times the O2 of the disposable unit, (good for ‘about’ 500 batches of beer). Tank gets hydrotested every 10 years and is easily, (and cheaply) filled at any participating welding gas company (check your local vendors). The tank will outlive us.
2. The O2 regulator has a control knob where you can adjust outlet pressure between 1/32 and 4 liters per minute.
3. A 22 inch stainless wand with 2 micron stone attached, so you can position the stone exactly where you want in the carboy and stay sanitary throughout the process. It’s attached to the reg with 5 feet of ¼ tubing.
These oxygen tanks have ISO stamps on them. Some vendors may claim that they can only fill DOT stamped tanks and not ISO. While this may be their policy, ISO is the current standard in the United States and abroad. These tanks are tested in Minnesota and more information about the differences between ISO and DOT stamps can be found here
