✨ Product Features
The liquid nitrogen doser is constructed with an aluminum outer shell and SUS304 stainless steel inner liner for excellent corrosion resistance.
The copper discharge tip delivers smooth, stable liquid nitrogen flow. The heat-insulated handle helps protect users from frostbite.
Canisters for both the doser and dewar are stainless steel. The dewar tank is aluminum alloy, with plastic lid and white plug.
The dewar tank adopts double-wall vacuum insulation, which lowers evaporation rate and extends liquid nitrogen retention time.

Let customers speak for us
from 6 reviewsI completed the second brew yesterday. The hop basket you made worked extremely well, and I was able to brew an IPA using homegrown hops.
Everything is functioning smoothly so far, and I think the brewing equipment is very well designed.
Thank you very much!
Best regards,
We couldn't be more impressed with the quality and service Wang and his team have provided us. Redwood Stainless engineers had no problem drawing and executing our custom tank design,which no one else would do. All of our tanks came outfitted with high quality fittings,valves,and carb stones. The welds are beautiful, and these fermenters are a real showpiece.
Having bought and operated several brewing systems now for our production brewery and brewpubs,we are continually impressed with the quality and customer service provided by Redwood Stainless Systems. They're adaptable and very willing to work with you to make sure you get exactly what you're looking for at very competitive pricing
Redwood has always provided me with the superior service that one can only hope for.I have been working with them directly for 5 years and have never been disappointed. Their customer service is great...Their engineering is great...Their fabrication is great. They are truly an invaluable resource not to be overlooked.
We are very satisfied with our tanks with no issues to date. No tank sweating,poor fabrication, or weld failures. We have not had any unsatisfactory or sanitary issues. We are satisfied with the product and will continue to order from Redwood Stainless.
Redwood Stainless, formerly DYM, is a fantastic resource for brewing equipment of every kind. At Culmination we have sourced tanks from several manufactures domestic and abroad and the Redwood tanks consistently outperform every other brand. They have been the workhorses of our brewery for a decade!
