Associated Steam Specialty Co.

Verabar® provides the most accurate, reliable technology for measuring gas, liquid and steam as well as the lowest operating and installation costs. HOW IT WORKS How it WorksWhen a fluid impacts the sensor, it creates a high-pressure zone in front of the sensor. As the fluid accelerates around the sensor, a low-pressure zone is created to the sides and rear of the sensor. Multiple sensing ports are positioned in these high and low-pressure zones and an averaged differential pressure is measured. Features and Benefits:

Armstrong unfired steam generators (USGs) are designed to produce pressurized clean steam using boiler steam or high-temperature hot water as an energy source. Typical uses for this clean steam include humidification, sterilization, pharmaceutical applications and food processing. USGs are constructed and stamped in accordance with ASME code. All tanks are registered with the national Board of Boiler and Pressure Vessel Inspectors, and an insurance compliance certificate is furnished. Unfired steam generators that generate 50 psi (3.4 bar) or greater steam pressure will be 100% X-rayed in accordance with the ASME code. Unfired steam generators from Armstrong are carefully designed to provide the correct balance of steaming area, coil size and control components to meet the specified requirements. In addition, they include an over-pressure safety system that will shut the unit down if the power fails. This over-pressure safety system closes both the feed-water and source steam valves, shutting the unit off.

HUMIDIPACK® The Armstrong HumidiPack is a prefabricated steam humidifier system that is ready for insertion in the duct. The HumidiPack consists of a separatorheader and multiple-tube dispersion assembly when supplied for use with an Armstrong steam-generating humidifier. A steam-supply control valve, strainer, steam trap and header drain traps are added when HumidiPack is used on pressurized steam. HUMIDIPACKPLUS® 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. HUMIDIPACK® CF 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. SIMPLIFIED INSTALLATION The HumidiPack Family dispersion assemblies slide neatly into ductwork or air-handling units. This frequently 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 headerseparator 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. 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). APPLICATION FLEXIBILITY Many sizes and configurations of the HumidiPack Family are available to meet new installation or retrofit needs.

Venturi tubes have long been specified and used in a multitude of flow measurement applications. The versatility of measurable fluids, line sizes, and material of construction available to a Venturi meter has made it a highly recognized differential pressure flow element. Armstrong offers classical style Venturi tubes – short form and long form – manufactured in accordance with applicable ASME codes. Also available is the Halmi Venturi Tube which features superior performance and design with shorter laying lengths and reduced cost.

SERIES D MANIFOLDS FOR DUCT-TYPE DISTRIBUTION Where an existing duct system is available, steam is commonly discharged into the duct through a dispersion tube. If the dispersion tube is to be located below the humidifier, install a drip leg with water seal. NOTE: For all atmospheric units, please consult factory personnel for duct applications with high static pressure (>4" W.C.) or velocities more than 2, 000 FPM. Avoid placing dispersion tubes in downward, high-velocity airflows. Please contact your Armstrong Representative with questions. NOTE: When applicable, atmospheric humidifiers should be located as close to the air-handling system as possible and never more than 40 feet (12 m) of equivalent pipe away.

Armstrong’s developments and improvements in refrigerated purger design and function have led to significant savings in energy, time and money. Armstrong offers three configurations to meet your individual needs: mechanical purgers, electric single-point purgers and Auto-Adaptive™ multipoint purgers. REFRIGERATION VALVES SOLUTIONS Armstrong introduces valve solutions for refrigeration systems. Armstrong’s state-of-the-art refrigeration valves are specifically designed for use in industrial ammonia and large commercial halocarbon refrigeration systems.
