Stainless Steel Drying Heater, Explosion-Proof Air Heater, 300kw High-Power Stainless Steel Duct Heater

Air Duct HeaterPrimarily used for air heating in ducts, available in three specifications: low, medium, and high temperature. The common structural feature is the use of steel plates to support the electric heating tubes to reduce vibration when the fan stops, with an over-temperature control device in each junction box. The low-temperature model can be directly installed in the duct, while the medium and high-temperature models, due to their structural differences, are sandwiched with 100mm thick insulating material between the duct exterior wall and the heater junction box. This not only reduces the overall heat dissipation of the duct but also decreases the temperature inside the junction cavity.
Advantages of Duct-Type Electric Heater:
1. Air duct electric heater heat exchange.
2. Even heat distribution; no hot or cold spots.
3. The duct-type electric heater boasts excellent safety performance.
Product Features
The electric heating tube is wrapped with a corrugated stainless steel strip, which increases the surface area for heat dissipation and significantly improves the heat exchange efficiency.
2. The heater is designed for optimal performance with low air resistance, even heat distribution, and no cold or hot spots.
3. Dual protection for enhanced safety. The heater is equipped with a thermostat and a fuse, which can control over-temperature of the air duct and prevent operation without air flow.
Air Duct Heater Product Applications: Heats air for various applications such as drying/sulfuring of different materials, heat treatment, reheating, dehumidification, and similar uses.
Application Fields
Air duct heaters are primarily used to heat the required airflow from the initial temperature to the desired air temperature, up to 850°C. They have been applied in many scientific research and production laboratories in aerospace, industry, chemical industry, and higher education institutions. Particularly suitable for automatic temperature control and high flow high-temperature combined systems and accessories testing.
The air electric heater has a wide range of applications: it can heat any gas, producing dry and moisture-free hot air that is non-conductive, non-flammable, non-explosive, non-corrosive, and quickly warms the heated space (可控).
