The AT-WM2 Series delivers large-area fire-water coverage with higher flows (20/30 L/s) so you can protect bigger bays with fewer devices and simpler piping. The ceiling-mounted layout keeps aisles clear and reduces infrastructure complexity, while two discharge modes (Water Jet / Water Spray) let operators choose range or spread to match the incident. Built with a rugged body (cast aluminum or stainless steel) for continuous duty, AT-WM2 is engineered for uptime and lower lifetime cost.

Where it pays off

• High-bay production lines, maintenance corridors, and NDT zones

• Material handling/transport areas and large equipment bays

• Warehouses, terminals/ports, energy & utilities facilities

• Aircraft hangars/MRO bays (when designed per applicable codes; foam proportioning optional)

Why choose AT-WM2

• High-flow performance: 20/30 L/s at 0.8–1.0 MPa for strong stream quality

• Ceiling-mounted coverage: fewer devices per zone; cleaner floor layouts

• Jet/Spray modes: target distance (jet) or near-field blanket (spray)

• Rugged construction: cast-aluminum or stainless-steel body options

• Design-friendly: DN80 inlet; recommended install height 8–15 m

Design note: Verify available pump flow/pressure at the DN80 inlet (include friction losses and elevation) to achieve the stated flow and coverage.
