PTC duct heaters use a PTC heater (semiconductor ceramic heater) as the heat source and are duct heaters for heating air in temperatures up to 100°C.

By adopting this PTC heater, the duct heater’s shape has been made about 1/4 of the size of conventional products. Furthermore, due to the excellent properties of the PTC heater, it has the following functions.

■Features

Compact

　Each PTC heater element has a compact size of 90 x 130 x 26t, and the shape of the duct body is 1/4 the size of conventional models.

Safety

　①The self-temperature control function prevents the heater surface temperature from rising above 230°C.

　②The heater surface temperature remains constant at a maximum of 230°C, so there is no need to worry about burning out even in windless conditions.

Energy saving

　①The self-temperature control function is a safety feature that allows the heater itself to control the amount of heat generated in response to increases or decreases in airflow.

　② Energy saving is achieved through self-temperature control that reduces the wattage according to the maximum heater surface temperature.

Quick response

　①It has a rapid heating function that reaches the maximum heater surface temperature (230°C) in 5 seconds.

　②It will heat up after 5 seconds and cool down after 20 seconds after switching it off.

Inexpensive

　The compact design has made it possible to reduce costs compared to conventional products.

Options

It is possible to install a blower and control panel.

*Our PTC heater (Z type) is equipped with AL fins to enhance the heat dissipation effect, resulting in a highly efficient structure.

Remarks:		Please use the hot air temperature at the outlet below 100°C. Ensure that the atmosphere around the heated object does not contain any condensation, moist air, or debris. If using in a special atmosphere, please be sure to contact us. The temperature and humidity of the installation location should be 0–40°C with 85% or less humidity. For temperature control, use airflow adjustment as the basic method. (If performing control by switching, please use ON/OFF control. However, note that the inrush current at ON will be approximately three times the steady-state current, so please be careful with the rating of the parts used.)
