Open Coil Outdoor UL VAV Duct Heat Pack Electrical Convection
Heater
Why TUTCO 1. Heater is UL listed for Outdoor Applications 2. All of the limit controls in all TUTCO duct heaters are automatic resets or are manually resettable. There are no devices that have to be replaced when tripped. 3. In a horizontal airflow application, the airflow direction is
not specific; it can go either direction without any modification. 4. With our wire rack element suspension system, the heater coil is
less susceptible to airflow shading and allows a very small
pressure drop across the coils. 5. All TUTCO duct heaters carry a zero clearance rating for
installations into ducts. Heating Sizing and Design 1. To size a standard slip-in heater with internal insulation in
the duct, refer to the diagram on the back side. 2. Design is available for all slip-in models. All heaters require power fusing. The following options are not available due to the sealed control box: SCR, Disconnect Switch, P.E. Switch, Pilot
Light, or Vapor Barrier. 3. Design can be used for DHD heaters to be used with a remote
panel.
