"G" Heat Exchanger Module
The GRE "G" unit is a self contained, compact, atmospheric gas fired heat exchanger module incorporating a clam type construction folded and welded heat exchanger with aluzinc casing, and air tight compartment for the burner.
Air for combustion is induced through the burner bars from underneath for good even air supply to the flame with good flame stability. The same fan unit draws the products of combustion from the top of the heat exchanger for discharge through a collar outlet. The burner compartment is completely 'room sealed" and makes the "G" unit ideal for mounting within Air Handling systems. All access for burner controls and maintenance is from the side thus enabling the primary air side to be completely sealed from the module compartment within an Air Handling Section.
Seven frame sizes with variations in gas burner rates and fans gives a total of Fifteen output rated units with maximum heat outputs ranging from 16kW to 107kW full fire.
The "E" unit provides a fully automatic electronic ignition pilot with ionisation flame monitoring for completely safe operation.
The "D" unit ignites the burner directly with ionisation flame monitoring for completely safe operation.
