ADCA MAS – Steam and Auxiliary Fluid Distribution Manifold

The ADCA MAS is a distribution manifold designed for installations requiring centralized supply branch connections. Primarily used in saturated or superheated steam networks, it can also be configured for water, compressed air, or other fluids upon compatibility verification.

Operational Use

The manifold should be installed in an accessible location for valve operation, branch isolation, and instrument monitoring. The condensate drain connection must be directed downward to a steam trap to remove condensate formed within the manifold body.

Technical Specifications

• Sizes: 4" to 12", DN100 to DN300.
• Connections: EN 1092-1 flanges PN16 or PN40.
• Alternatives: ASME B16.5 Class 150 or 300.
• Threaded connections: ISO 7 Rp or NPT on request.
• Body material: P235GH / 1.0325.
• Heads: P265GH / 1.0425.
• EN flanges: P250GH / 1.0460.
• ASME flanges and sockets: ASTM A105 / 1.0432.

Variants

• MAS-H: horizontal steam distribution manifold.
• MAS-WH: horizontal manifold for liquids.
• MAS-GH: horizontal manifold for gases.

The unit can be delivered as a complete assembly with valves, pressure gauges, and steam trap station, depending on P&ID and isolation requirements for each branch.

Selection Criteria

For proper technical selection, the following are required:

• fluid type,
• maximum operating pressure and temperature,
• manifold diameter,
• number of inlets and outlets,
• DN of each branch,
• drainage position and DN,
• insulation requirements,
• instrument and gauge connections.

Installation must be supported adequately, avoiding load transfer from piping or thermal expansion to the manifold body.

Compliance

The MAS is designed for Group 2 fluids per PED 2014/68/EU. As a non-standard construction with variable volume and operating conditions, conformity assessment and CE marking are case-specific. It is not considered equipment with an inherent ignition source under ATEX; grounding and equipotential bonding are evaluated per project.

FAQ

Does it replace a field steam manifold?
Yes, when organized distribution of multiple branches from a single point is required.

Is a steam trap always necessary?
In steam applications, manifold drainage must be provided to prevent condensate accumulation.
