Standard Construction Features

 

Heating Elements – Industrial grade, 0.475” diameter steel sheath with brazed copper plated steel fins and epoxy sealed ends. Draw-thru airflow design pulls air across the heating elements to ensure cool element operation and even air distribution resulting in long element life.

Housing – Heating elements and motor are enclosed in a heavy gage galvanized steel cabinet with a durable polyester powder coat finish.

Outlet Grille – Individually adjustable louvers are provided to direct airflow. A protective outlet fan guard is provided to prevent insertion of foreign objects.

Fan Motor – Permanently lubricated and thermally protected motor.

Built-in Controls – All units include an automatic reset thermal cutout that will de-energize the heater if an over-temperature condition occurs. A manual Standard Construction Features reset thermal cutout, in addition to an automatic reset thermal cutout, is standard on heaters 10 KW and above. A fan relay is provided to allow the elements to heat up before fan startup and purges the heater of residual heat after shutdown. A 24-volt transformer and disconnecting contactor are provided on most heaters. Single-phase heaters rated at 5 KW or less have line voltage controls; 24-volt control and contactor are available. Power fusing is standard on all heaters rated over 48 amps.

Mounting – Universal horizontal or vertical discharge. Optional diffusers are available for vertical discharge. An Anemostat diffuser can be used to provide draft free air movement at lower mounting heights.
