Open coil electric air heater made by Jaye industry 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. Due to the resistance wire exposure, they are only suitable for use in low velocity installations due to the risk of the coil coming into contact with other coils and shorting the heater. In addition this exposure can pose risks of foreign objects or personnel coming into contact with the live electrical wire. 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.
