PTC Self-Limiting Cartridge Heaters for Radiators

Positive Thermal Coefficient (PTC) technology applied in heating provides a heating power that is a function of temperature, thus giving maximum power at lower temperature and reducing power output as temperature nears required level.



- Intrinsic safety
- Self-regulating
- No risk of overheating
- No thermostat cycling
- Both vertical and horizontal mounting

ADVANTAGES

Intrinsic safety: PTC heaters steadily drop power output when thermally insulated. When in dry air, for example, absorbed power drops to insignificant levels, thus avoiding the typical effect of traditional heaters, which tend to burn out.


No thermostats nor fuses needed, therefore no consequent risks. The required temperature cannot be exceeded by PTC elements.

Any working position: the absence of thermostats permits either horizontal or vertical orientation of the heater during operation.

No risks in case of partial filling of radiators: parts above level simply drop heating power, whereas with traditional heaters with thermostats situated on top this can be fatal.

Smaller diameter (also for Class II heaters) than in traditional heaters provides a wider installation capability.

Low voltage sensibility: when voltage varies within applicable voltage range, effects on power output are limited.

Very fast warm-up phase, followed by constant temperature thereafter.

- Power range: 50900 W (when immersed in water at 25C and fed with 230V).
- Voltage ranges: 100160 V or 160250 V (standard).
- Class I or Class II, to EN 60335-1, IP64 protection, Y-type connection.
