Improvement in the at industrial facilities environment can produce substantial benefits in terms of increased production C.J. Miles Raptors Jersey , reduced errors, and a decline in complaints and absenteeism among employees.

Air-Handling Units for Make-Up Air and Space Pressurization Applications have the following features:

- Outlet Temperature is usually monitored with a probe mounted near the outlet of the unit.

- Discharge Air Temperature is set at the control panel or using a remote control station.

- Gas input is “modulated” using a butterfly valve, actuator, and controller.

For Space Heating Applications Kyle Lowry Raptors Jersey , a room thermostat is used to control outlet temperature. On a call for heat, the unit will provide air heated to the maximum allowed temperature until the room thermostat is satisfied. Once satisfied, the unit will either turn off or will continue to operate at a reduced outlet temperature.

An override option may also be supplied. In this case a room thermostat is supplied in addition to the basic system. The unit is set to full-fire when room temperature falls too low.

Direct Spark units are supplied with an ignition transformer for the igniter.

Piloted Units are supplied with a solenoid-operated Automatic Pilot Valve and a small pressure regulator – around 20,000 BTU – as well as an ignition transformer for the pilot spark igniter.

Pre-purge of the system (by starting the blower for a specified time to provide a minimum air volume change) before ignition of main burner is not required by ANSI code Kawhi Leonard Raptors Jersey , but is frequently specified by the user.

To assure safe operation of a direct gas-fired heating system, a number of Safety Interlocks are commonly provided:

A. Damper Limit Switch – Dampers must be fully open before unit will operate.

B. Air Proving Switch – Located near outlet of unit to prove air flow before igniting burner.

C. Flame Supervision – Discussed above. Shuts down unit on flame failure.

D. High Temperature Limit – Signals unit to reduce gas supply when maximum allowable temperature is reached. If air temperature exceeds limit, the unit is shut down.

E. High Gas Pressure Switch – Shuts down unit to protect regulator against spikes in inlet gas pressure.

F. Low Gas Pressure Switch – Shuts down unit when low inlet pressure detected. Redundant safety device, since low flame would also shut down unit.

G. Safety Shut-off Valve – Responds to various inputs listed above – closes off gas supply.

Return Air Units are widely used for direct fire space heating applications. They can be supplied with a maximum 80% return 20% fresh air Authentic Serge Ibaka Jersey , per ANSI standards.

All return air should be brought in downstream of the burner and not recirculated through the burner. This is to prevent buildup of waste products from the combustion process within the building. It also prevents contaminants originating within the building environment from being passed through the direct fire burners. T.
