Calorflex
Constant Power Drain Heater
A compact constant-power drain heater cable range for refrigeration, air conditioning and cold room applications where frozen condensate or blocked drain lines can interrupt equipment operation.
Technical snapshot
Key CPCx drain heater specs.
Core details for selecting the correct output, planning the cable path and checking temperature limits before the heater is fitted to the drain application.Drain line freeze protection
Consistent heat output for cold room drains and condensate paths.
The CPCx range is a double-conductor constant-power heating cable intended for industrial refrigeration, especially cold room applications. The heating section is identified by marked connection points at 500mm intervals, helping technicians plan the run and apply controlled heat where drain flow needs protection.
- Constant-power heater cable for refrigeration, air conditioning and cold room drain applications.
- Helps reduce ice build-up, frozen condensate and blocked drain lines during low-temperature operation.
- Suitable for drain channels, condensate lines and refrigeration equipment where controlled heat is required.
- Available through Omni as CPCB1600, CPCB3300 and CPCB4800 options.
- Calorflex CPCx platform supports optional metal braiding for mechanical protection and earthing.
Where it helps
CPCx is suited to systems where condensate has to keep moving through low-temperature equipment, especially when drain channels and pipework are exposed to freezing conditions during normal cycling.
- Cold rooms, freezer areas and industrial refrigeration equipment.
- Drain channels, condensate lines and low-temperature pipe runs.
- Air conditioning and refrigeration equipment where ice formation affects drainage.
Drain heater selection
Pick the output to suit the drain run and freezing risk.
Compare the listed wattage options against the drain path, exposure, control method and electrical supply. The right option should maintain drain flow without forcing tight bends, sharp transitions or unprotected contact points.
Check routing, output and protection before fitting.
- Match the wattage to the condensate load, drain length and surrounding temperature.
- Keep the minimum 15mm bend radius through bends and equipment transitions.
- Confirm the cable path is protected from crushing, abrasion and sharp edges.
- Allow for termination, control hardware and electrical protection required by the installation.
Listed low-output option for compact drain heating requirements.
Mid-range listed option for drain lines needing extra heat output.
Highest listed Omni option for higher-output drain heater applications.
Remove ice, debris and restrictions before fitting the heater cable into or around the drain route.
Verify supply voltage, load, protection, earthing and control requirements before energising.
Avoid sharp edges, crushing, tight bends and contact points that could damage insulation or create hot spots.
