Standard Construction Features

Every standard UHIR unit heater is constructed with standard features:

• Heating Elements: Industrial grade, 0.475″ diameter steel sheath with brazed copper plated steel fins and epoxy sealed ends. Draw-thru airflow design allows air to be pulled across the heating elements to ensure a cool element operation and even air distribution that results in a long element life.
• Housing: Heating elements and motor are enclosed in a heavy gauge galvanized steel cabinet with a durable polyester powder coat finish.
• Outlet Grille: Individually adjustable louvers are provided to allow 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 will include an automatic reset thermal cutout that will de-energize the heater if an overtemperature condition may occur. A manual 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 are 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: Every unit will have 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. For higher mounting heights, radial diffuser with adjustable fins can be used to increase floor coverage or adjusted for a vertical down blast of air.
