The Q-Pak heating system includes a 3.0 MMBtu/hr (other sizes can be used as necessary) air heater with a recirculation duct system, insulation, control valves, burner management system, recirculation blower, and a tool test enclosure.

The blower circulates the air through the heater into the duct system to the tool test enclosure.  In the tool test enclosure the heated air flows down to the bottom of the enclosure through an annular space between the outer housing and inner casing.  The heater air then flows upward through the inner casing passing over the tool.  The air exits the top of the tool test enclosure to the duct system where it is returned to the blower inlet.

The system allows for recirculation of the air from the test enclosure to save on fuel costs.  In the recirculation mode, 20% of the air flow will be exhausted and made up with fresh air.  This keeps the oxygen level high enough for proper burner operation.  There are three butterfly control valves in the duct system to control the recirculation of the air, exhaust air and fresh air.  The valves have electric actuators that provide the option of using 100% fresh air and bypassing the recirculation mode.  In the recirculation mode the heater can be operated at temperature up to 500 ^oF.  In the 100% fresh air mode the heater can be operated at temperatures up to 1000 ^oF.

The heater controls, fuel system and junction box are mounted on the heater providing interconnections to the heater for the fuel gas, pilot gas, pressure switch, low flow switch, flame scanner, igniter and thermocouple.  The control panel is shipped separately for remote mounting in the control area of your facility.  The motor starter is mounted to the heater and is wired to the motor and junction box with galvanized conduit.
