Raychem Oil and Grease Line Temperature Maintenance Systems

Greasy waste lines are pipes used for the disposal of waste oils and fats from kitchens and catering facilities. Thermal insulation of the pipes is often insufficient to keep greasy water free flowing in the lines in many cases. The Raychem electric heat-tracing system provides flow-maintenance for greasy waste lines for both above-ground and buried piping.

Flow maintenance involves heating a fluid in order to lower its viscosity so that it can be moved through a pipe or a tank. A grease-line flow maintenance system is designed to maintain 40°C (104°F) fluid temperature to keep the Fat, Oil and Grease mixture (FOG) in suspension from the kitchen to the grease interceptor.

Typical Applications

  • Greasy waste lines in commercial restaurants
  • Pre-wash stations
  • Floor drains.

The Technology

Raychem self-regulating systems offer the most flexible approach for heat-tracing design. Cable can be cut to length on site for the most complex installations.

System features include:

  • Selectable temperature levels: Maintain or Economy temperature
  • BMS compatible
  • Control units can be put in a network for fast programming
  • Nine building-specific programs
  • Alarm relay for remote monitoring
