Custom HERMS Coil

Order today at a special TheElectricBrewery.com price! GO »

Coiling the HERMS coil has proven to be one of the most difficult aspects of building our brewery for many users (see some of the failed attempts).

We are now proud to offer custom stainless steel HERMS coils that have been professionally manufactured to our specifications by a US-based stainless tubing company, ready for use in our electric brewery setup.

The longer 50 foot length ensures that heat transfer is maximized and the large 1/2 inch tubing minimizes flow restriction.

What size do I need?

Two sizes are available:

STANDARD: 15.5" diameter, 7" high. Will work in any kettle with an inner wall diameter of 15.5" or larger such as the 20 gallon Blichmann Boilermaker or larger.
SMALL: 11.25" diameter, 9.5" high. Will work in any kettle with an inner wall diameter of 11.25" or larger such as the 10-15 gallon Blichmann Boilermakers or 15 gallon kegs (keggles).

The ends of the coil extend approximately 2" past the diameter to allow the user to cut to the exact length they need as every kettle will be slightly different.

Specifications

Total length: 50 feet
Material: 1/2 inch OD 304 stainless steel
Ends: Bent at a 90 degree angle to exit straight out of kettle wall, lining up perpendicular with each other.

Assembly instructions are available in our Complete Guide to Building your Home Brewery or online here.

If only you would make these with a smaller diameter, so the would also be compatible with kegs converted to brew kettles

Should I be concerned with the ink text on the coil, and if so, what should I use to remove it?

Best Regards

Good question. I remember years ago when I first built my setup my coil had writing on the outside too. I believe I used a slightly rough scouring pad and some oxyclean to remove it.

My Herms coil has writing on it. I've probably heated 20 batches of water and it's still on there. Even Star San isn't removing it. I don't think it will hurt anything.
