This is cool. Our line freezing specialist, Jeff, sent me this video today. It’s a double 8″ nitrogen line freeze in the basement of an aquatic facility in South Surrey, with the nitrogen plumbed in from the trucks in the parking lot. It’s the safest and most efficient way to do a line freeze with limited nitrogen handling.
Nitrogen boils at -210 Deg.C (-346 Deg. F) and is able to freeze most liquids. Give us a shout if you want more information or pricing. Or, visit our website at https://pacificflowcontrol.ca
