Calorflex
Evaporator Pan Heater Range
Calorflex CPTCx evaporator pan heaters are cartridge-style PTC heaters for refrigeration and cold room equipment where condensate trays, evaporator pans and drain areas need freeze protection.
Technical snapshot
Three listed cartridge heater options for evaporator pans.
Core CPTCx range details for selecting the correct cartridge length, output and installation style for refrigeration drain and pan heating work.Drain and pan freeze protection
Help keep condensate moving during defrost cycles.
The CPTCx range is designed for refrigerated counters, cabinets, display cases, cold rooms and freezer equipment where condensate water can freeze in pans or around drain areas. The PTC cartridge element delivers stronger heat output when cold and reduces output as the cartridge temperature rises.
- Evaporator pan heater / cartridge heater range for HVAC/R and refrigeration service work.
- Helps prevent ice build-up in condensate trays, evaporator pans and drain areas.
- Supports reliable water drainage during defrost cycles.
- Compact cartridge format for placement through or alongside pan heating zones.
- Suitable for refrigerated cabinets, evaporators, drain trays and condensate pans.
Where it helps
Use CPTCx heaters where frozen condensate can block drainage, cause overflow, increase service calls or allow ice to build up around refrigeration components.
- Cold rooms, freezers and refrigerated cabinets.
- Evaporator pans, condensate trays and drain channels.
- Equipment operating through repeated defrost and low-temperature cycles.
Range selector
Pick by cartridge length, output and available pan space.
Match the cartridge length and wattage to the pan size, the drain area being protected and the available mounting position. Confirm the supply, control method and clearances before installation.
Start with the coldest section of the pan or drain path.
- Check where condensate freezes first during operation or defrost.
- Choose the cartridge length that fits the pan or channel without obstruction.
- Confirm the listed output suits the evaporator pan size and duty.
- Plan the cable exit, electrical connection and control hardware before fitting.
CH1010/110W cartridge heater for compact evaporator pans and confined tray areas.
CH2020/230W cartridge heater for mid-size pans and higher heating requirements.
CH3030/330W cartridge heater for larger pans, longer drain areas or stronger output needs.
Confirm the cartridge can protect the area where ice build-up affects drainage.
Verify supply voltage, load, protection, earthing and any control requirements before installation.
Avoid damage, sharp edges, trapped cables and installation positions that can restrict water flow.
