Description

Larger cabins and common areas needing 12,000 BTU of central chiller cooling find their match in the Webasto A12 Compact Air Handler, sized to move meaningfully more air than the A6 or A9 while keeping the same compact single-blower footprint. This mid size cabin chilled water unit fits salons, master staterooms, and other rooms with real square footage to cool.

At this capacity, the handler is doing genuinely heavier lifting than the smaller models — moving 560 m³/h of air rather than the 380-420 m³/h of the A6/A9 — which matters for rooms with higher ceilings, more glass, or simply more volume to bring down to temperature and hold there.

Key Features of the Webasto A12 Compact Air Handler

This webasto a series 12000 btu unit steps up the airflow and chilled water demand proportionally from the smaller A-Series models, without changing the fundamental single-blower compact design.

Innovative Instant Drain Condensate Management System handles condensate automatically
High-quality stainless steel construction throughout
Flexible vibration isolation mounts and larger ducts reduce operating noise
Oversized heat exchanger tested specifically under tropical operating conditions
Compatible with the Webasto MyTouch color touchscreen control display
