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.

Open coil elements are the most efficient type of electric heating element while also the most economically feasible for most heating applications. Used predominantly in the duct heating industry, open coil elements have open circuits that heat air directly from the suspended resistive coils. These industrial heating elements have fast heat up times that improve efficiency and have been designed for low maintenance and easily, inexpensive replacement parts.
