We are very happy with the immersion elements we’ve purchased from you (2 18KW incoloy elements for use in a brewery setting). They get heavy use, and after 6 years on the one and 1 year on the other they both work as well as the day we installed them. The outer cover gets quite a bit of spray and we’ve never had any water intrusion. Combined with the service we received on ordering, and the price point, we really couldn’t be more happy. Thank you.
