Sinton Little Classroom: How to Choose the Right Air Duct Heater for You

With the continuous advancement of industrial technology, air duct heaters have become indispensable equipment in many fields. Today, let's talk about how to choose a duct heater that suits you.

1. Understand the application field and requirements

Air duct heaters are widely used in multiple fields such as power plant boiler conversion, drying room conversion, tunnel furnace conversion, and coal-fired power conversion. Before choosing a heater, it is essential to clarify your application field and specific requirements, including temperature requirements, air volume requirements, size restrictions, and material selection, etc. Only by having a thorough understanding of the on-site working conditions can we recommend the most suitable products for you.

2. Power selection

The power supply is the key to the normal operation of the heater. The thermal efficiency of the electric furnace is as high as 95%, so the output is almost equivalent to the heat generated. When choosing a power supply, it is necessary to consider the time required for the heating medium to reach the set temperature from its initial state, as well as the heat output needed to maintain the medium temperature under working conditions. Sinton Group offers a variety of power options to ensure that your diverse needs are met.

3. Wind speed and air volume design

Wind speed and air volume are important factors affecting the performance of the heater. We can measure the wind pressure, wind speed and air volume inside the air duct through professional measuring tools such as pitot tubes, U-shaped pressure gauges, oblique micromanometers and hot bulb anemometers, etc. Ensuring that the wind speed and air volume are reasonably designed can enhance heating efficiency and reduce energy waste.

4. Requirements for electric heating tubes

The electric heating tube is the core component of the heater, and its performance directly affects the heating effect and service life of the heater. When choosing electric heating tubes, we need to pay attention to key indicators such as heating time, rated power deviation, leakage current, insulation resistance, insulation withstand voltage strength, on-off capacity, overload capacity and heat resistance. All the electric heating tubes produced by Sinton Group have undergone strict quality inspection to ensure they meet all performance indicators.

5. Cabinet appearance and material

The appearance and material of the cabinet are also factors to be considered when choosing a heater. Sinton Group offers a variety of material options, including carbon steel, stainless steel 304/201 and galvanized sheets, as well as multiple thicknesses and size specifications to meet the needs of different customers. Meanwhile, we also offer a variety of flange types and variable diameter types to ensure that the heater is perfectly matched with your air duct system.

6. Configuration of electrical appliances and other parts

Apart from the electric heating tubes and the appearance of the cabinet, the configuration of electrical components and other parts is also an important factor affecting the performance of the heater. Sinton Group offers a complete range of electrical configurations, including junction boxes, distribution cabinets, temperature controllers and temperature probes, etc. We ensure that all electrical components comply with national standards and industry norms to guarantee the safe, stable and reliable operation of the heater.
