Air Heater Factory

-- Steady & Reliable Manufacturer --

Introduction

Sinton Electric is a specialized air heater factory, committed to producing high-performance, clean, and efficient heating solutions for air and gas streams. Our air heaters are designed for rapid heat-up and precise temperature control, utilizing robust tubular or open-coil heating elements. As a manufacturer, we provide a wide range of standard and custom-built heaters for applications requiring reliable, on-demand hot air, from comfort heating to complex industrial processes.

SINCE 2001

Sinton Electric Co.,Ltd.

Sinton Group was created in Yancheng City, Jiangsu Province. Sinton Electric Co., Ltd. is one sub-company of the Sinton group which started its business in 2001, We have formed a comprehensive group with energy-saving heating products as the mainstay, including import and export trade. Sinton's production base is its subsidiary China Hopebond Eco-Tech Co., Ltd., which is a national high-tech enterprise. The self-built 60-mu factory is located in Tinghu Environmental Protection Industrial Park. It has a production plant of 20,000 square meters and an R&D center of 3,600 square meters. It focuses on technological innovation and brand creation. , Specializing in the production of explosion-proof and non-explosion-proof heaters, air duct heaters, pipeline heaters, circulation heaters, electric drying machines, heat-conducting oil furnaces, Electromagnetic coil heaters, and all kinds of electric heating elements, such as direct thermal energy providing element or preheater of project. The products are mainly suitable for high-temperature heating environments of 50-1000℃ and are widely used in environmental protection, medical treatment, coal mining, petroleum, chemical industry, textile, plastics, heating, agriculture, animal husbandry, and other fields, and to promote the development of Zero-Carbon Economy and green earth conversion.

Frequently Asked Questions

Q: What information do I need to specify a duct heater?
A: You need the duct dimensions (width x height), the required air temperature rise, the air velocity (CFM or m³/h), and the available voltage.

Q: What is the difference between an open coil and a tubular air heater?
A: Open coil heaters have a very low mass and heat up/cool down almost instantly, but they are more fragile. Tubular heaters are more durable and can handle higher pressures, but have a slower response time.

Q: Is a high-limit thermostat necessary?
A: We highly recommend it. A high-limit thermostat is a safety device that shuts off the heater if the air flow stops, preventing overheating and potential damage to the heater and downstream equipment.

Q: Can these heaters be used with corrosive gases?
A: Yes, for corrosive environments, we can build the heater using corrosion-resistant materials like Incoloy 825 or 316L stainless steel for both the sheath and the housing.

Q: How is the heater controlled?
A: Control is typically done via a temperature controller and a contactor. For more precise control, a solid-state relay (SSR) can be used for proportional control.

Q: What is the minimum air velocity required?
A: This depends on the heater's wattage and design. There is always a minimum flow rate required to carry heat away and prevent the element from overheating. We will specify this for your custom design.

Q: Can you build explosion-proof air heaters?
A: Yes, we can design and manufacture air heaters that meet specific ATEX or other explosion-proof standards for use in hazardous environments.

Q: Are finned heaters more efficient?
A: Finned heaters increase the surface area, which improves heat transfer to the air. This makes them more efficient and allows for a more compact heater design for a given wattage.
