NOTE: When selecting a 60 Hz blower for use on 50 Hz,
a pressure and capacity calculation is required. See
Eclipse Combustion Engineering Guide (EFE 825).
The total selection information you should now have:
• blower model number
• motor hp
• motor enclosure (TEFC)
• voltage, number of phases, frequency
• rotation direction (CW or CCW).
Air pressure switch
The air pressure switch gives a signal to the monitoring
system when there is not enough air pressure from the
blower.
You can find more information on pressure switches in
Blower Bulletin 610.

■ Eclipse Combustion supports NFPA regulations,
which require the use of an air pressure switch in
conjunction with other safety components, as a
minimum standard for main gas safety shut-off
systems.

WARNING

Step 7: Main Gas Shut-Off Valve Train

Consult Eclipse
Eclipse can help you design and obtain a main gas shut-
off valve train that complies with the current safety
standards.
The shut-off valve train must comply with all the local
safety standards set by the authorities that have
jurisdiction.
For details, please contact your local Eclipse Combustion
representative or Eclipse Combustion.
NOTE: Eclipse Combustion supports NFPA regulations
(two shut-off valves) as a minimum standard for main gas
safety shut-off systems.

Step 8: Process Temperature Control System

Consult Eclipse
The process temperature control system is used to control
and monitor the temperature of the system. There is a
wide variety of control and measuring equipment
available.
For details, please contact your local Eclipse Combustion
representative or Eclipse Combustion.
