PTC Air Heaters - SS Type

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).

Customized Length(L)

Calculate the length of the PTC heater according to the length and the number of PTC chips used in one set of standard PTC. The length of each PTC chip is 24mm, maximum number of PTC chips can fit in one set is approximately 15 chips. If require longer PTC, please contact us for special designs.

Example:
Length(L) = Length of PTC(24) x Num. of PTC heaters + 1mm
              = 24 x 5 + 1 = 121mmL

Customized Width(W)

Width of the PTC heater can be extended by combining standard PTC sets, please see example below for calculation.

Example:
Width(W) = Width of 1 standard PTC set x Num. of PTC sets + 0.5mm
               = 22 x 5 + 0.5 = 110.5mmW

PTC Heater Thickness(T)

The thickness of a Standard PTC heater set is 15mm. If require additional silicon glue seal the thickness of the PTC heater will increase slightly. Please advise our Sales representatives if you require silicon glue to be added to your PTC heaters.

PTC heaters with silicon glue will have the following advantages:

• Humidity prevention
• Prevent silver electrode on PTC chips from oxidizing
• Reduce the possibility of sparks caused by short-circuit of positive and negative electrodes in high humidity conditions.
• Stronger bonding, reduce the possibility of PTC breakage due to strong impact or shocks.
• Better exterior

Calculate Power(W):

A single PTC chip is approximately 60~120W depending on the air flow and air volume (heat dissipation rate). User can calculate the approximate power according to the size of the desired PTC heater. Please see examples below for calculation:

Example 1: Power of smallest SS type PTC heater (22 x 22.5 x 15mm)
Number of PTC chips = 1
Power(W) = 60~120W

Example 2: Power of largest SS type PTC heater (361 x 330 x 16mm)
Number of PTC chips = 15 x 15 = 225 pcs
(1 standard PTC set has max. 15 chips, with total of 15 sets)
Power(W) = 60~120W x 225 = 13500W~27000W

Customized SS Type PTC Heaters - Non-Standard PTC sets

For PTC heaters that require higher power(W) within the same or smaller space. Our glued typed PTC air heaters can be customized to have a row of PTC chips with each row of aluminum fin. Please refer to image below for available sizes for Non-Standard PTC sets:

Customized Width(W)

Width of the PTC heater can be extended by combining PTC chips with aluminum fins. Please see below example for calculation:

Example:
Width of aluminum fin = 10mm
Width of PTC Chips = 2mm
PTC set = 1 layer of aluminum fin + 1 layer of PTC chips = 12mm

PTC Heater Width(W) = Width of 1 PTC set x Num. of PTC sets + 10.5mm
               = 12mm x 8 + 10.5mm = 106.5mmW
