FTWH100 | Series of forced circulation heaters

The heating element housing is made of precision die-cast aluminum, offering strong corrosion resistance and resistance to high and low temperatures; a protective cover is added to the heater to prevent burns.

The internal heating element and sealing end caps are made of stainless steel, providing strong corrosion resistance; a sealing ring-type drain valve is located at the bottom of the heating element for use when needed.

The control system uses a microprocessor for measurement and control, detecting input voltage and heating wire current, and providing anti-dry-burning and overheat protection functions.

Temperature sampling uses a PT100 sensor, and a color LCD displays the temperature and operating status. The coolant temperature can be set via the control panel. The circulating water pump and heating element are controlled separately. Before heating, the water pump is turned on first, and the heating element is turned on after a 60-second delay. Upon reaching the set temperature, the heating element is de-energized first, and the water pump is de-energized after a 60-second delay. This prevents heat concentration and extends the water pump's lifespan.

Communication methods: One CAN communication channel, one RS-485 communication channel, and USB communication. The product has a manual testing function, allowing users to test the heating element and water pump's proper operation via panel buttons.
