Heating elements in cartridge shape or in special executions equipped with self-regulating resistance elements.
Heating of liquids, preheating of oil and petrol, frost protection,heating of blocks for medical and test equipment
The self regulating cartridge heater type HLPR is a compacted heating element with PTC-effect (positive temperature coefficient: performance decreases the more that the temperature increases).
When the temperature on the sheath of the heater increases, the performance is automatically reduced due to the increasing resistance within the PTC elements. The cartridge heater regulates itself, any additional control equipment is not required.
The specification of the self regulating cartridge heaters type HLPR needs to be adapted to it`s individual application. Please let us know your technical requirements.
Available Diameters: 10, 11, 12 . 16 mm
Available Voltages: 10–30 V; 100–140 V; 200–265 V
Compared to conventional high performance cartridge heaters with a nearly constant ohmic value, HLPR heaters consist of an integrated semiconductor element. The resistance of the heater varies and increases automatically with the rising temperature and the power consumption and the current is reduced to a minimum when the heater reaches its maximum temperature. This makes the heater very economical and extends its lifetime.
