What is the difference between S.A.M. wands and Multi-Steam™?

S.A.M. (Steam Absorption Manifold) wands are ideal for smaller capacities and narrow ducts. Multi-Steam™ SD/HD is designed for high-capacity applications and wide ducts, offering a shorter carryover distance.

In what situations is the SDU used?

The SDU (Space Distribution Unit) is used when steam from the humidifier needs to be delivered directly to the space. It is preferred in large open areas without duct systems (warehouses, manufacturing facilities).

Which humidifier models is the distribution system compatible with?

Distribution systems are primarily used together with SKE4, SKS4, and SKD. The appropriate distribution element should be selected based on the capacity and pressure of the steam source. Contact our technical team for combined system design.

DISTRIBUTION

Multi-Steam™ Distribution

Steam distribution systems evenly distribute steam from the humidifier into the airstream. Multi-Steam™ SD/HD systems are ideal for both in-duct and in-space applications. S.A.M. and S.A.M.E2 distribution wands adapt to different duct widths. The SDU (Space Distribution Unit) provides direct humidity distribution in ductless spaces.

Applications

Central HVAC systems (AHU)

Fan coil units

Ductless space humidification

Air handling systems

In-Duct Distribution Wand

S.A.M.

Short Absorption Manifold

Absorption Distance

< 1.5 meters (5 ft)

S.A.M. (Short Absorption Manifold) is a stainless steel distribution wand with inserted brass steam nozzles. It prevents condensate from escaping into air ducts and channels accumulated condensation back to the humidifier or steam trap. Custom-built for specific duct dimensions.

Technical Specifications

Tube Material	304 stainless steel dispersion tubes
Nozzle Material	Brass eyelets extending into tube interiors
Welding	Continuous seam weld construction
Absorption Distance	< 1.5 meters (5 ft)
Assembly	Factory-welded or collapsible field assembly
Installation	Horizontal or vertical distribution
