How Armstrong’s gas-fired HumidiClean™ works
When there is a call for humidity, the
pre-combustion safety check confirms that the duct-pressure switch, duct
high-limit humidistat and liquid-level control circuits are satisfied.
The microprocessor then signals the blower to turn on, and the
humidifier’s blower-pressure switch senses air movement.
The unit then signals the ignition-control module
to perform a purge cycle. The hot-surface igniter comes on and, after it
comes up to temperature, the gas valve opens and gas ignition occurs.
The flame-detection rod senses the presence of the flame, and combustion
is underway. The humidifier accepts a 0-10 Vdc control signal and
provides proportional output in response.
- Uses natural gas or propane for economical operation
- Category I/III gas-fired appliance
- Energy cost savings in comparison to electric humidifiers
- Wide range of humidity outputs to cover a variety of applications
- Modulated control of steam output
- Steam output turndown ratio of up to 30:1
- Low NOx infrared burner
- 82% efficiency rating
- Ionic bed technology to reduce cleaning and maintenance
- Pressure switch senses air movement in the blower and back pressure on the unit
- Ignition-control module monitors combustion of the unit
- Flame-detection rod senses flame during combustion
- Liquid-level control prevents a low-water condition
- Tank low-level probe provides redundancy to avoid low-water condition
- Stack over-temperature sensing prevents overheating
- Tank insulation prohibits access to hot tank surface
- End-of-season drain eliminates standing water during periods of no demand
NOTE: This product is available
with the Armstrong Temp-R-Drain, a device that mixes hot condensate and
cold water to maintain a drain outlet temperature suitable for drainage
directly to any plumbing system. Contact Armstrong factory
representatives for more information.
