ExpressPack® Multi-Tube Steam Dispersion Panel
ExpressPack® is a multi-tube steam dispersion panel that accepts atmospheric source steam and discharges it into a duct or air handling unit.
Packaged with Armstrong Steam Generating Humidifiers
ExpressPack® is designed to accept steam from the following Armstrong humidifiers:
- Series EHU-700 (electric)
- Gas Fired HumidiClean™
- Series CS-10 Steam-to-Steam
ExpressPack® uses a series of unique dispersion tubes spaced to provide a shorter non-wetting distance than conventional individual tubes. Each tube includes two rows of diametrically opposed
Dispersion tube spacing is selected to optimize performance while minimizing excessive condensation. ExpressPack® components are typically shipped loose for field assembly, minimizing initial cost.
The ExpressPack® panel disperses a dry and uniform discharge of steam. Stainless steel steam headers and dispersion tubes are sized to match application requirements for proper separation and coverage of the face area. The discharge nozzes extend inside the dispersion tube to insure steam is discharged rather than condensate to avoid spitting. Nozzle sizing and spacing also assists in providing a uniform discharge of steam across the face area. Each header includes a large 1″ NPT drain connection to assure proper condensate drainage.
Used primarily in horizontal air flow applications, ExpressPack® is ideally oriented with a horizontal header and vertical dispersion tubes. ExpressPack™ may be located in an air handler or duct. For duct applications, the panel’s best location is near a joint in order to make installation practical. Care must be taken to minimize the distance of steam line run to ExpressPack™ from the steam generating humidifer. With nozzle steam discharge perpendicular to air flow, ExpressPack™ adapts well to high air flow velocity applications.
