Description
Cabins needing 9,000 BTU of cooling from a central chiller system get a properly sized match in the Webasto A9 Compact Air Handler, fitted individually in each room to draw chilled water from the boat’s central plant. This compact chilled water cabin unit sits between the A6 and A12 in Webasto’s capacity lineup, suited for medium-sized cabins or busier common areas.
Getting handler capacity right per room is what makes a central chiller system feel genuinely comfortable rather than just adequate — a 9,000 BTU handler moves enough air to keep a mid-sized salon or master cabin cool without the oversized airflow and noise of stepping up a size, or the underperformance of stepping down.
Key Features of the Webasto A9 Compact Air Handler
This medium cabin webasto handler brings the full A-Series comfort feature set to a capacity tier suited for rooms larger than a berth but smaller than a full salon.
- 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

Webasto A9 Compact Handler FAQ
What voltage rating does this system use?
Webasto BlueCool A9 utilizes a standard 230V power input. This single-phase electrical design is perfect for international harbor grids and heavy-duty yacht generator circuits, allowing vessel owners to install premium climate management setups without retrofitting or overloading lower-voltage ship service lines on their primary vessel distribution boards.
What are the physical dimensions of this unit?
Webasto BlueCool A9 features a footprint of 12.6x11.1x11.6 inches. These tight dimensional limits facilitate easy drop-in mounting behind salon bulkheads or inside cockpit storage lockers, presenting an efficient installation alternative for vessel retrofits when older, bulkier mechanical climate hardware setups are being updated or replaced entirely.
When is this Webasto unit best applied?
Webasto BlueCool A9 is best applied as an independent climate solution for small master cabins. This modular air handler unit integrates a heavy-duty copper header evaporator heat exchanger coil to drop cabin heat indexes rapidly, managing relative humidity efficiently when paired with a remote multi-stage central chiller system.
