Duct type auxiliary electric heaters are generally used to assist in heating the air supply in the duct during the heating process of central air conditioning units, to compensate for the insufficient heating caused by low ambient temperatures, improve operating efficiency, reduce the workload of the host, and extend the service life of the host. This product can also be used for other types of air heating and drying purposes.

Compact structure, simple and convenient installation, no need for too much maintenance after installation, can be made waterproof or explosion-proof in special environments..

Heaters have the advantages of rapid heating, low air resistance, uniform heat dissipation, and high thermal efficiency.

Equipped with a temperature control switch and a thermal fuse protector (model/temperature to be determined according to specific requirements), it can use AC contactors or thyristors for temperature regulation and over temperature protection. In emergency situations, the emergency stop switch can be turned off..

This product has mature and stable technology, and all materials are high-temperature resistant, with a long service life.

The explosion-proof hot air blower is made of high-quality stainless steel, modified protactinium oxide powder, high resistance electric heating alloy wire, stainless steel heat sink and other materials. It is manufactured through advanced production equipment and processes, and has undergone strict quality management. This series of products can be installed in blowing ducts or other stationary, flowing air heating occasions. Fin type electric heating tubes are made by wrapping metal heat sinks around the surface of ordinary components, which increases the heat dissipation area by 2-3 times compared to ordinary components. In other words, the surface power load allowed by fin components is 3-4 times that of ordinary components. Due to the shortened length of the component, its own heat loss is reduced. Under the same power conditions, it has the advantages of fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device volume, and low cost. Reasonable design has been carried out according to user requirements for easy installation. The product is widely used in industries such as mechanical manufacturing, automotive, textile, food, and home appliances, especially in the air conditioning curtain industry.

Process: The finned heating tube is composed of fins wrapped around the outer surface of the heating tube to dissipate heat.

Usage: Used for heating ovens and drying channels, usually with air as the heating medium.
