Reasons to use stainless steel
There are two main instances which require a stainless steel duct heater. First, the heater is located near shore and the heater will be exposed to a salt laden moist airstream. The second is for corrosive installs such as petrochemical plants and waste water treatments plants.
Questions to ask
What is the location of the heater, will it be located indoors or outdoors? This question should be asked to appropriately select the correct heating element style of either open coil or finned tubular regardless of the general request for stainless steel heater construction. If indoors, should the air stream be unfiltered, moisture laden or corrosive one should consider finned tubular elements. Secondly, if the installation is outdoors we strongly suggest finned tubular elements over open coil elements in all cases for variable conditions which may include moisture laden or corrosive air streams.
Assuming, the customer is interested in stainless steel construction including stainless steel elements and frame, further discovery should be considered in regard to optional terminal box construction such as NEMA 12 type and NEMA 3R type.
Once we have qualified aspects of element, frame and terminal box construction we may move forward with particular requirements such as control features and performance requirements.
