Armstrong HumidiClean™ electric and gas-fired humidifiers utilize remarkable, ionic bed technology for more efficient operation, increased energy savings, and close to maximum output throughout their service life.
Ionic Bed Technology
HumidiClean™ humidifiers feature replaceable, ionic bed inserts. This technology is backed by years of field-proven success in thousands of humidifier installations. The ionic bed consists of a fibrous medium that attracts solids from the water as its temperature rises, minimizing scale buildup on the heat exchanger and inner tank walls. An ionic bed weighs approximately 3/4 pound when it's new, but after absorbing its capacity of solids, it may weigh more than four pounds. When this occurs, a signal light on the humidifier tells you to change the ionic bed inserts—a simple, 15-minute task.
HumidiClean™ Saves Time, Energy and Money
Most humidifiers drain every 20–45 minutes because of carbonate buildup. However, the ionic beds attract these carbonates from the water, so the primary reason to drain the HumidiClean™ tank is to eliminate sodium. Since this is typically necessary only once every 12 hours, HumidiClean™ greatly reduces the amount of hot water wasted, and delivers real savings in energy costs.
HumidiClean™ requires less maintenance and downtime associated with humidifier cleaning, including:
- Reduces cleaning of tank heat exchanger and drain screen—allowing for effective tank blowdown
- Lowers heat-exchanger surface temperatures, with no output reduction
- Decreases water and energy consumption due to fewer required tank blowdowns
- Eliminates the need for wasteful surface skimmers
HumidiClean™ Series HC-6000 Electric Steam Humidifiers
How HumidiClean™ works: Once power is supplied to the unit, the water fill valve energizes and water enters the tank. When the level reaches the low-water switch, the heating elements are energized (assuming there’s a call for steam output). The unit continues to fill until the high-water switch is energized. HumidiClean™ responds to the humidistat's input signal by producing steam. If all conditions remain constant, the tank will fill at regular intervals. Periodic tank drainage is based on active time of the heating elements, but it may be field-adjusted to water conditions.
Designed for Safety
Armstrong HumidiClean™ passes no current through water. Its resistance-type design has a proven track record for safety. Individual compartments keep the plumbing completely separated from the electrical components. Other safety features we've built into HumidiClean™ include: a key-locked access door, error light, continual-checking diagnostic routines, high- and low-water-level detection, internal tank temperature sensing, over-current protection, and connections for a Class 2 alarm device.Learn More
Gas-Fired Steam HumidiClean™ Series GFH
The Gas-Fired HumidiClean™ from Armstrong operates economically on natural gas or propane. It is adaptable to various water qualities, and service life cycle and tank drainage are field-adjustable. HumidiClean™ is CSA-certified and CGA-approved.
How Gas-Fired Steam 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. Next, the unit 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.
Advantages of Gas-Fired Steam HumidiClean™
- 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
At Armstrong, our improvements in steam humidification are fundamentally different because they begin with the steam, not the humidifier. To condition steam, we use the following four-step process, developed by our experts. First, the steam is slowed and particulate matter is removed. Next, the condensate is separated, and the steam is dried. In the final step, the steam is silenced. Unlike units that simply disperse steam, Armstrong’s direct-steam humidifiers work with the steam, guiding it through the many steps of our unique, carefully engineered process.Learn More
HumidiPack® Steam Dispersion Panels
Armstrong HumidiPack® is a prefabricated steam humidifier system that is ready for insertion in the duct. The HumidiPack® consists of a separator/header and multiple-tube dispersion assembly when supplied for use with an Armstrong steam-generating humidifier. When HumidiPack® is used on pressurized steam, a steam-supply control valve, strainer, steam trap and header drain traps are added.
The HumidiPack® Family dispersion assemblies slide neatly into ductwork or air-handling units, which typically reduces the time and labor required for field installations. Units with horizontal tubes and vertical headers offer all piping on one side of the ductwork or air handler to simplify piping.
Corrosion-Resistant Stainless Steel
The header/separator and dispersion assembly of the HumidiPack® Family are of rugged stainless steel, providing a long, trouble-free service life. To minimize maintenance, tube-to-header joints are welded stainless steel rather than assembled plastic adapters with o-rings.
The HumidiPack® Family includes a variety of sizes and configurations to meet new installation or retrofit needs.
Compatibility With Many Steam Sources
HumidiPack® may be used with Armstrong Series CS-10 Steam-to-Steam humidifiers and gas and electric steam-generating humidifiers. HumidiPack® is also compatible with systems that have packaged boilers or a central steam supply to 60 psig (4 bar). The HumidiPackPlus™ and HumidiPack® CF may be used with packaged boilers or central steam supply to 60 psig (4 bar).
Reduced Heat Gain To Duct Air
Since no steam is admitted to the manifold assembly unless there is a demand for steam output, there is no heat gain to duct air when HumidiPack® and HumidiPackCF™ are not in use.
HumidiPackPlus™ combines the absorption (non-wetting) distance-shortening performance of HumidiPack® with the additional feature of steam-jacketed “active” tubes. The result is a dry, uniform discharge of steam for nearly any application with a steam source from a pressurized central supply.4
HumidiPack® CF offers the performance of HumidiPackPlus™ without the need of jacketing steam on pressurized steam applications. Typically used with a vertical header configuration, HumidiPack® CF offers excellent separation of entrained moisture from steam with preheated active tubes. The entire face area is cold during periods of no demand, adding no energy to the air stream.
Steam Quality Monitoring
Steam quality plays a crucial role in the sterilization process, so it is essential for patient safety and reducing hospital-acquired infections. Armstrong provides state-of-the-art solutions for steam quality monitoring, such as Steam QM®-1.
Steam QM®-1 Steam Quality Monitoring
By detecting the dryness fraction of steam entering autoclaves, Armstrong's Steam QM®-1 enables you to maintain the steam quality necessary to ensure proper sterilization and avoid pitting of instruments. Even more importantly, Steam QM®-1 helps prevent the dangerous wet packs that can stop or delay surgery, costing hospitals and physicians time and money and creating an infection risk for patients.
Steam QM®-1 is an automatic steam quality monitor that continuously determines and communicates the dryness fraction of the steam. Although manual methods of measuring steam dryness fraction are still in use, they are time-consuming, inconsistent, less reliable and present inherent safety and accuracy risks. Automatic testing has proven to be a more reliable and consistently accurate way to monitor and measure steam quality.
