Stainless steel explosion-proof electric heating tubes are mainly used for air heating in air ducts, with three specifications: low temperature, medium temperature, 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, and the junction box is equipped with an over temperature control device. The low-temperature type can be directly installed on the air duct, while the medium temperature type and high-temperature type, due to structural differences, have a 100mm thick insulation material sandwiched between the outer wall of the channel and the heater junction box, which reduces the external heat dissipation of the entire channel and also reduces the temperature inside the junction box.

Structure of air duct heater

1. The air duct heater uses stainless steel heating tubes as the heating element

2. Use carbon steel or stainless steel materials as brackets

3. Constructed using a combination of connection methods

Product features of air duct heater

1. The electric heating tube adopts an externally wound corrugated stainless steel strip, which increases the heat dissipation area and greatly improves the heat exchange efficiency.

2. The heater design is reasonable, with low air resistance, uniform heating, and no high or low temperature dead corners.

3. Double protection, good security performance. A temperature controller and fuse are installed on the heater, which can be used to control the air temperature in the air duct to work in extremely warm and windless conditions, ensuring that everything is foolproof.
