PTC Air Heaters

The PTC heat output can be regulated by the airflow applied in typical applications of heat generation. The higher the airflow, the higher the heat output and power(wattage).

PTC Model Selection

KLC’s standard Non-wired models and our new Wired models are available for selection for different applications:

	Non-Wired (Standard)	Wired (NEW)
Image
Power In	Positive (+) and negative (-) inputs on either sides	Single sided Positive (+) and negative (-) inputs
Wiring	Wires with female terminals required	Can be connected to power directly
Standard Frames	Available	Available
Accessories & Terminal Wiring	Available (Options: single-stage/multi-stage power setting wiring)	Require customization
Limitations	No current and power(W) limitations	≤15A : ≤1800W
Suitable Applications	Most suitable for standard applications where power connection is not limited to single side. Vast scope of heating applications.	Most suitable for applications where power connection is fixed on a single side. Better vibration endurance for automotive. Prevent loose connection or poor contact between terminals. Reduce the possibility of oxidation of connection points between male and female terminals, causing increase in resistance leading to overheated joints and vibration failure. Additional silicon seal can be added for applications located in high humidity environments. Effectively increase the life expectancy of PTC air heaters.
