  • CO2 lines freezing - Vaporizer or heater?

    Good afternoon,

    We recently upgraded our brewery's secondary regulators to a higher flow model, and it's causing freezing issues with our 350# microbulk system (actual snow forming on the regulators and hoses). I've been reading about solutions for this, and it seems like the two most viable options are installing a vaporizer between the tank and the secondary regs, or installing an inline heater on the tank. I'm kind of leaning towards the heater since it'd be a one-time purchase instead of a rental from our gas supplier, but I'd just like to get feedback from people who have had to solve this problem before.

    In a way, I'm wondering if anyone has had any *bad* experiences with vaporizers and/or CO2 heaters that I might want to avoid.

    Hey Guybehindawall,

    As a third option, you might look at doing a surge tank. We currently run about 1,500 BBL/Year off a similar sized CO2 system and were having (expected, I suppose) regulators freeze up as well. We did add a heated regulator but the real difference came when we plumbed in a 60 gallon, 200 psi surge tank. Now when our keg cleaner calls for CO2 purges, etc, it can draw on that tank without pulling liquid through the regulator.

      What is your gas consumption per minute? Check your carbonation gas demand + Keg purging + Tank purging gas demands. I guess your gas lines are very small to handle a huge amount of gas demand. Ask your gas technician to design the line as per the demand. A bigger diameter line could help.
