Safety Thermostats
There are two safety thermostats on the device that activate at 70°C and 110°C. When the internal temperature of the device exceeds 70°C, the immersion-type 70°C thermostat cuts off the circuit, shutting down the heating contactor circuit. In case of any malfunction in the 70°C thermostat, the manual-reset 110°C thermostat cuts off the contactor circuit when the temperature reaches 110°C. Pressing the Reset button is required for the device to come back into operation. It is recommended not to operate the device without airflow to prevent this problem, which is commonly encountered when the device is run without adequate ventilation.

Control Panel
Depending on customer demand and the heating power, an internal or external type panel application can be implemented on the device. Panels, which use equipment suitable for the requested control scenario, are specially manufactured, tested with scenario tests, and delivered to the customer in working condition.

On/Off Step Control Panel
It consists of two parts: the control card and the digital control panel. It provides On/Off control up to 3 steps. The digital control panel allows the user to adjust the temperature, monitor the temperature, and perform manual/automatic temperature control. It is used together with the step contactor circuit inside the panel.

Proportional Step Control Card
It performs On/Off control up to 3 steps with a 0-10V control signal sent from an external control panel and/or automation system. It is used together with the step contactor circuit inside the panel.

Power Thyristor
It provides proportional control with a 0-10V control signal sent from an external control panel and/or automation system. Necessary control is ensured by selecting a product suitable for the total power of the electric heater produced as a single step.

Air Flow Switch
It is a safety device that prevents the operation of the electric heater when there is no airflow. It is connected in series to the contactor circuit.

Temperature Sensors
They are used for temperature measurement in the channels to which the heaters are connected. Temperature control or limitation of the heater output temperature is carried out with the control panels to which they are connected.
