Grease Waste Flow Maintenance
Chromalox’s heat tracing system is designed to prevent kitchen waste from clogging pipes from the kitchen to the remote grease interceptor. The system parts include:
- CPR Heating Cable with Fluoropolymer outer jacket
- DL Series Connection accessories
- CTC controller or CTS Digital Thermostat
- RTD temperature sensor
- DL Attachment Accessories (including attachment tape, pipe straps and caution labels)
- Thermal Insulation (provided by others)
Use of Heat Trace in the Application:
Most fat, oil and grease (FOG) begins to congeal at 100 degrees F. As kitchen waste from dishwashers, sinks and floor drains enter drain pipes, it is critical that the pipe’s temperature be maintained at about 110 degrees F.
- Please note that National Electric Code requires ground fault protection (GFEP) for all heat tracing.
Important Design Notes/Best Practices:
Calculate heat losses based on the following:
- Type and thickness of insulation
- Pipe material and diameter
- Expected worst case ambient temperature
Calculate number of circuits based on the following:
- Supply voltage
- Circuit breaker size
