INDUSTRIAL HEATING EQUIPMENT

Control Equipments

Safety Thermostat
There are two safety thermostats which activates at 70°C and 110°C
on the device. When the temperature inside the device reaches over
70°C, immersion type 70°C thermostat desactivates and closes heater
contactor. In case there is a breakdown in 70°C thermostat, when
the temperature reached up to 110°C thermostat, 110°C thermostat
with manual reset desactivates contactor. Reset button must be pushed
so that the device could reactivate. Generally, the devices should not
be started up to prevent this problem which is frequently encountered
when the device is started up without air-flow.

Control Panel
Upon the request of the customer, internal and external type panel
application can be made on the device. Panels, on which equipment
suitable for the requested control scenario is used, are custom
manufacturing and submitted to the customer in working condition by
completing scenario tests.

On/Off Mode Control Panel
It consists of two-piece structure as Control card + Digital control
panel. It has On/off control opportunity with its 3 stages. User
temperature setting, temperature display, manual/automatic
temperature control can be done through the digital control panel.
Mode can be used together with the contactor circuit in the panel.

Proportional Stage Control Card
It provides On/Off control up to 3 stages with 0-10V control signal to
be sent from an external controller and/or an automation system. It is
used together with mode contactor circuit in the panel.

Power Thyristör
It provides proportional control with 0-10V control signal to be sent
from an external controller and/or an automation system. Required
power is established via the product with the same power amount of
the electrical heater manufactured as single-stage.

Air Flow Switch
It is a safety equipment which blocks working of the electrical heater in
case there is no air flow. It is attached to contactor circuit serially.

Temperature Sensors
They are used for measuring temperature in the ducts to which
the heaters are attached. Controlling or limiting the heater exit
temperature is conducted through control panels to which they are
attached.
