ManiPack Steam Distribution Manifold Assembly

The Armstrong ManiPack is a pre-assembled, steam-jacketed distribution manifold bank made specifically for air-handling units. The ManiPack is for applications that require a direct-steam-injection humidifier such as the Series 9000 or 1000. Designed for economy and ease of installation, the ManiPack includes convenient mounting tabs for easy attachment, an optional all-stainless design for D.I. service, no black iron piping and standard interchangeable parts. The ManiPack is designed for applications where it is desirable to use multiple steam-distribution manifolds to achieve a downstream non-wetting distance (i.e., “vapor trail”) as short as three feet. For non-wetting distances less than three feet, the Armstrong HumidiPack family should be considered. Calculation of the non-wetting distance can be performed with the Armstrong Humid-A-ware^™ Humidification Sizing and Selection Software.

Steam jacketing is desirable because it improves steam quality and reduces the chance of spitting or dripping condensate into the air-handling system. For applications sensitive to duct heat gain, it is advisable to keep steam-jacketing pressures below 20 psig (1.3 bar).
