An open coil heater is a high-efficiency heating element designed for direct air and gas heating. Unlike enclosed heaters, its exposed resistance wire coils allow rapid heat transfer to the surrounding air, making it ideal for applications requiring fast response, high temperatures, and unrestricted airflow. These heaters are commonly used in HVAC systems, industrial drying, and process heating due to their low thermal mass, energy efficiency, and simple construction.
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of open coil heater for air & gas heating in China, also supports custom service. Welcome to wholesale high quality open coil heater for air & gas heating at competitive price from our factory.
An open coil heater is an efficient heating element that can be used for the direct heating of air and gas. Open coil heaters consist of exposed resistance wire coils and therefore the heat can be quickly transferred to the surrounding medium (air) in fast response applications at high temperatures and as long as there are no obstructions to the airflow.
In HVAC, industrial drying and process heating applications, open coil heaters can be used widely due to the low thermal mass, high efficiency and simple construction.
