Description

The largest single-blower handler in Webasto’s A-Series, the A18 Compact delivers 18,000 BTU for sizeable salons, master suites, or open living areas that need serious cooling capacity from a central chiller system. This large cabin chilled water unit moves nearly double the airflow of the A12, the next size down.

At 750 m³/h of airflow, this unit is built for spaces where a smaller handler would struggle to keep pace — big open-plan salons, cabins with substantial glass area, or rooms that see heavy daytime use and need to recover quickly after doors or hatches open.

Key Features of the Webasto A18 Compact Air Handler

This webasto biggest single blower handler represents the top of the single-blower A-Series range before Webasto’s larger models step up to dual-blower designs at 24,000 BTU and beyond.

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
