Open Coil Heater

Open coil heaters made by Jaye industry have the features of high heating transfer effiency, safety, stable and long time service life. And the open coil heaters are one type of air heaters that expose the maximum resistance heating element surface area directly to an airflow. Open coil elements consist of an exposed resistance wire (typically Ni-Chrome) crimped onto terminals and strung between ceramic insulators. A variety of different wire gauges, wire types and coil diameters are commonly used depending on application needs. The benefit of open coil elements, however, is that they have low thermal inertia, resulting in typically very fast response times and their small surface area allows for reduced pressure drops.
