1, Overview

What’s the fins surface uncharged PTC heater?

Different with surface charged PTC heater, the surface uncharged PTC heater doesn’t have electricity in its aluminium surface. The PTC thermistors, to be in charge of heat production, have been placed well inside of some layers of yellow insulated paper. PTC heating element has been fixed in the aluminum tube through hydraulic press. To send out heat in time, the tubes with PTC thermistors have been surrounded by a lot of layers of aluminum fins. It is assembled by fins assemble machine. As its insulation, this PTC heater is safer than surface charged PTC heater, so it has wider applications.

For easily assembly, this kind of fins PTC heater usually brings with two brackets. The brackets can be aluminium, for insulation the brackets assembled with software silicone plugs. It is easy for user to fix it with screws.

2. Specifications of fins surface uncharged PTC heater

Item	Description
Material	PTC thermistors and aluminium fins, joined with soldering and gluing. The material of brackets is stainless steel.
Dimension	Check the dimension sketch map and specification. For the same width of PTC heater, the length can be customized.
Rated voltage	100-240V, it can be customized.
Rated power	For this sample it is 1500W. It can be customized
Withstanding Voltage	The withstanding voltage test will input 2 times of related voltage to the PTC heater for 1 minute.
Inrush current	It is about 1.5-2 times of related current when power on for about 10-15 seconds.
Power supply	AC electricity or vehicle power.
Assembly mode	For client to assemble the PTC heater easily, this PTC heater brings with two stainless steel brackets.
Wires	Usually use fire resistance wire or Teflon wire.
Wires length	Can be customized according to client’s need
Surface charged	Uncharged.
PTC thermistors	The PTC thermistors have been plugged into the aluminium tube and been squeezed by liquid pressure machine. To make this heater insulated, these thermistors are covered by two layers of yellow insulated film before being plugged into the tube.

Temperature control	This heater unit doesn’t have temperature limiter. For special requirements, we can add it.
Package	Bubble bag, can be customized

3. The features of fins surface uncharged corrugated heater series.

3.1 Its surface is uncharged, it is insulated and safe even been touched with the conductive object.

3.2 Easy installation, plug-and-play, fast temperature increase.

3.3 No oxygenation and open flame, secure and comfortable use. Quiet operation, and do not generate RFI noise.

3.4 It has a virtually unlimited service life, the service life is up to 100,000 hours.

3.5 Automatic adjustment to maintain balanced and continuously heating. When the temperature is too high, it will automatically reduce the power, reduce the heating and keep the temperature constant. High operational reliability and energy efficiency without any additional switching elements.

3.6 The fins provide higher heat transfer efficiency. And the structure of fins deposit less dust than ripple PTC heater.

3.7 Product size, voltage, power, temperature and other parameters can be customized.

4. The possible applications of fins surface uncharged fins PTC heater

This kind of surface uncharged fins PTC heater are usually been used for high value products, such as air conditioner, high level air heater.
