WHY HEAT-TRACE GREASY WASTE SYSTEM?
• Commercial kitchens increasingly use passive
grease interceptors to prevent discharging
grease to the waste water system.
• Building design trends are pushing
interceptors further away from the kitchen.
• Clogged grease lines force shutdown of
commercial kitchens.
• Reasons to keep the waste effluent hot
(40°C)
1. Fat, Oils and Grease (FOG) separates
best when the effluent is relatively
warm.
2. Keeping FOG from coalescing on the
solids is important
Heat-tracing is a low cost, reliable solution

TYPICAL GREASY WASTE PROJECTS
Industry Trends Favor Our Solution
THERMAL MANAGEMENT
• Any Building Containing Restaurants
Large developed areas will have rules requiring the use of waste interceptors.
• Airports
Food prep areas are typically located in the center of the structure and
require long lines to reach buried interceptors.
• Mixed Use Retail and High Rise Buildings
Retail space commands a premium and as a result engineers are pushing
interceptors further from kitchen spaces resulting in additional greasy waste
piping.
• Company Offices with Kitchens
Large company campus project have onsite kitchens to encourage employees
to stay on site. Typically these kitchens are close to office space and require
substantial lengths of pipe to reach interceptors.
• Hospitals, Hotels, Casinos
Many have kitchens a long distances from interceptors. All have significant
costs if the kitchen has to shut down.

GREASY WASTE FLOW MAINTENANCE
 Above ground and buried pipe
 40°C maintain temperature
typical
 Application with FS-C-2X or
31XL2-ZH.
 Tees and splices are installed
using pipe mounting brackets,
not in direct contact with piping
Keep pipe and fluid warm and flowing until the interceptor

SUMMARY
• Flow maintenance within a grease trap pipe is essential in avoiding blockages
• Grease waste receptors are often away from the kitchen area and therefore the
pipework needs to be heated to ensure flow is maintained.
• Maintaining 40 °C pipe temperature aids flow of grease and fat by lowering
viscosity.
• TraceCalc Pro for Buildings enables system design with actual onsite
environmental factors and pipe/insulation types.
• Thermal Management provides full design and installation support for the
application
