The Chromalox SDRA Super Dragon is a rugged, self contained, mobile electric blower heater that can be used with or without optional inlet or outlet 20” diameter flexible duct. The SDRA units can be used for comfort heating or process heating temperatures to 180º F, and can be located in an ambient of up to 130º F.
The SDRA includes a fan only switch, that allows the unit to be used to recirculate room air, supply fresh air source, or capture fume exhaust. The SDRA heaters provide for easily adjustable airflow for a wide variety of applications including flexible ducting up to 165 feet in length. Each unit includes two thermostats to enable the operator to set the maximum inlet and outlet temperatures, magnetic contactor(s), a 120 volt control transformer, power on pilot lights and a high limit cutout to protect the heater against unintended low air flow conditions.
The SDRA can be left unattended without the threat of fire or by-product of combustion from fuel fired heaters. The bright red polyester powder coated heater can be easily moved because of two 10” diameter pneumatic wheels on the outlet and a 4” lockable swivel castor on the inlet.
