This may sound cold, but it's true. When your valves are protected by a Hot Box® enclosure, they are able to withstand temperatures as low as -30 degrees.

How do we know? because Hot Box® is ASSE certified for freeze protection, and not every one of our competitors has this certification.

No wonder Hot Box® sells more enclosures than anyone else - because when it comes to low-temperature conditions, we're a hot commodity.
