Open coil heaters are air heaters that expose the maximum heating element surface area directly to an airflow. The choice of alloy, dimensions, and wire gauge are strategically chosen to create a custom solution based on an application’s unique needs. Basic application criteria to consider include temperature, airflow, air pressure, environment, ramp speed, cycling frequency, physical space, available power, and heater life.

Recommendations

For applications in a humid environment, we recommend the optional NiCr 80 (grade A) elements.
They are composed of 80% Nickel and 20% Chrome (does not contain iron).
This will allow a maximum operating temperature of 2,100o F (1,150o C) and installation where condensation may be present in the air duct.
