Flow Maintenance Applications
A flow maintenance system is designed to maintain cooking greasy waste lines and #2 fuel
oil lines above the temperature at which the viscosity inhibits fluid flow .
Typical Flow Maintenance System
A typical flow maintenance system includes the XL-Trace self-regulating heating cables with
a fluoropolymer outer jacket, connection kits, line-sensing temperature control and power
distribution .
