The HOT BOX® is designed to enhance the installation of backflow prevention, pump, and sprinkler assemblies, pressure vacuum breakers, air release valves, etc. in the most economical, accessible location - outside, above ground. More and more designers, utilities, and contractors are putting the BFP "at the curb" to eliminate the problems encounterd in equipment rooms (no costly floor space, drainage constraints...) and pits (OSHA 29 CFR, parts 1910 flooding, accessibility ...) Engineered features such as heater sizing (freeze protection), drain sizing, service access, and rigid construction make the HOT BOX® the permanent solutions to the problem of protecting your outdoor piping systems.
