EC fan heater and cooler controller
Industrial fan heater controller to heat warehouses or manufacturing plants. This controller regulates fan speed and controls an external water valve. The higher the difference between
the measured temperature value and the temperature setpoint, the higher the EC fan speed. The unregulated output controls a water valve or an electric heating element. All parameters can be adjusted via Modbus RTU communication.
Additional specifications and description
Fan heater controller for warehouses and production facilities
Industrial fan heaters are a good way to heat large halls such as warehouses or manufacturing plants. Air is drawn in, heated up and blown back into the room. Thanks to the mechanical supply of warm air into the space, it can be heated up more quickly. Higher efficiency is achieved thanks to the mechanical supply of the warm air. The use of industrial fan heaters is particularly recommended in industrial environments or logistics centers. It is the ideal solution for blowing warm air through a space with many obstacles such as machines and warehouse racks.
Fan speed can be set manually or automatically
To avoid overheating, heater and fan are always enabled simultaneously. The included PT500 temperature sensor measures the ambient temperature. The desired temperature can be selected via the rotary button on the front panel or via Modbus RTU communication. When the ambient temperature is lower than the desired temperature, the heating is activated via the unregulated output (ON/OFF). At the same time, the fan is also activated. Fan speed can be controlled automatically (AUTO) or it can be fixed at a constant speed (positions 1 - 2 - 3 - 4 or 5). In position 0, the device is disabled. When the ambient temperature is higher than the setpoint temperature, heater and fan are disabled.
Adjust settings via Modbus RTU communication
For most applications, this controller can be used with its default settings. If necessary, these default settings can be adjusted via Modbus RTU communication. It is advisable to use the 3S Modbus software to adjust the settings. A free download is available via our website. To connect the computer to the ECH controller, we advise to use the optional connection set CNVT-USB-RS485-SET.
