Do you know how to use the duct heater correctly?

Pipe heaters are essential equipment in the manufacturing industry. They are widely used in various industries, including automotive, textiles, printing and dyeing, papermaking, refrigeration, washing machines, food, pharmaceuticals, and chemicals. They achieve ultra-fast drying. They offer excellent radiation effects, significant energy savings, and are easy to use and maintain.

Pipe heaters are compact, take up minimal space, are easy to move, offer strong corrosion resistance, provide uniform heating, eliminate hot and cold corners, and offer high thermal efficiency. Thick insulation between the stainless steel inner and outer shells minimizes heat loss, maintains temperature, and saves energy.

Pipe heater installation and use:

The pipe heater control cabinet should be installed in a dry, well-ventilated area with easy access. The water pipe heater housing and control cabinet housing should be reliably grounded. The water pipe heater should be mounted horizontally, and the base nuts should be tightened for stability. When installing the main unit and external receiving channel, pay attention to the inlet and outlet orientation. Before using a water pipe heater, measure the insulation resistance between the power supply terminal and the metal casing to ensure it is not less than 2MΩ. The relative humidity in the operating environment should not exceed 85%. The power cord inlet and outlet must be secure and not loose. Before use, check that the power cord and temperature sensor output connections are correct, and check that the control cabinet components and nuts are not loose or damaged. Tighten or replace any abnormalities immediately. Once confirmed, power on and conduct a test run. The main steps are as follows:

1. Turn on the water pipe switch. The power indicator will illuminate, and the digital display control light will illuminate and display the measured temperature value.

2. Set the temperature.

3. Once the temperature is set and there are no abnormalities, press the "Heater On" button. This will energize the AC contactor, energize the solid-state relay input, and control the heater using the PID signal output by the digital temperature controller. During initial startup, the temperature may overshoot, but will gradually return to a stable range.
