KLC’s Standard PTC Air Heaters are designed with single stage heating (full power). However, MH type PTC Air Heaters can be designed with multiple power stage by heating one or two tubes at a time. It is more power efficient and will help extend heater life-time. If require multiple stage heating, please contact our Sales Representatives in advance for special design and wiring.
PTC’s unique heat property allows the PTC heat output to be regulated by the airflow applied. The higher the airflow, the higher the heat output and power(wattage).
Notes on Part Numbering
1. PTC FIN PITCH (MH-XXXXS):
- The Power(W) in the Specifications table is based on PTC air heaters with fin pitch 1.2mm(S).
- The power(W) of PTC air heater with fin pitch 2.0mm(N) is 95% of PTC air heater with fin pitch 1.2mm(S)
- The power(W) of PTC air heater with fin pitch 2.6mm(B) is 90% of PTC air heater with fin pitch 1.2mm(S)
2. PTC INSULATION (MH-XXXXS-XXXS):
- The Power(W) in the Specifications tables are based on PTC air heaters with Single Insulation(S).
- The price of PTC air heaters with double insulation(D) is 20~30% more than single insulation(S) PTC air heaters.
- The power(W) of PTC air heater with double insulation(D) is approximately 10% less than PTC air heater with single insulation(S).
- The PTC air heater with Double Insulation(D) does not have electrode potential on the fins. It is suitable for use where the device may be in contact with other conductive materials (eg. metal); expose to high humidity; with shock resistance requirement; or in products that require superior stability and quality (eg. automobiles).
3. ACCESSORIES (MH-XXXXS-XXXSX):
- The “Other Accessories” in 4, 5, 8, B and D of Part Numbering will not include Thermostat for PTC air heaters with Maximum Inrush greater than 14A.
- However, if specifically require thermostat to be included, please advise our Sales Representatives for possible alternatives.
