Section 2
2.2.7 Atmosphere Supply Gas - CDA
FURNACE PROCESS GAS SYSTEM
Plant supply process gas must be filtered and regulated to 70 psi before the furnace to assure consistent clean
dry process gas is supplied during furnace operation. An internal gas reservoir with check valve further
regulates gas pressure to 15 psi for the belt tensioners.
If the furnace air pressure drops below the set point during operation, the operator should put the furnace into
Cool Down. The operator can reset the system to Warm Up when air pressure is again over 70 psig.
Table 2-3 Gas Supply Pressure
Location Default
Setting
Plant Process Gas Regulator
70-110 psig
4.8-7.6 bar
Furnace Regulator (optional)
60-70 psig
4.1-4.8 bar
Low Pressure Alarm Switch
55 psig
3.8 bar
See Section 3 for information calibration and service of the pressurized gas (N
2
/CDA) system.
WARNING: The flowmeters on these furnaces are rated at 70 psi maximum. Operating
above 70 psi exposes the operator to possible injury.
Flow Meter Default Settings
Select the Gas Flow button. The Gas Flow screen will be shown. Open the furnace flowmeter access panel
and adjust the gas flow to the default flows indicated on the screen or per process recipe requirements. See
Owner’s Manual, Engineering section for default settings. See Reference Manual, Chapter 9, Balancing Gas
Flow for information on setting the flow meters to balance the system gas flow.
