Quality heaters since 1957

Q-PAK Direct Fired Air Heaters

The Q-Pak direct fired air heater is a robust direct fired air heater, ideal for heating air streams that can allow for mixing the products of combustion with the process air stream. The Q-Pak direct fired air heater utilizes an internally mounted raw gas duct burner located in the flow path of the process air stream. As the process air flows over the burner, it also supplies the combustion air necessary for the burner to operate. In applications where the air flow is not sufficient to maintain stable combustion, an external blower can be supplied. Fuel is piped into the burner, where it mixes with the process/combustion air. The resultant flame heats the air stream with very high efficiencies. 

The heater controls, fuel system, and junction box of the Q-Pak direct fired air heater are mounted on the heater providing interconnections to the heater for the fuel gas, pilot gas, pressure switches, low flow switch, flame scanner, igniter and thermocouple. The control panel can be locally mounted on the heater, or shipped separately for remote mounting in the control area of your facility. A process air blower motor starter can be supplied mounted to the heater and is wired to the motor and junction box.
