Webasto A18 BlueCool A-Series Compact Air Handler – 18,000 BTU – 230V

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.

Why Choose the Webasto A18 Compact

This unit carries Webasto’s standard 2-year warranty, and at 1A running current it’s still a modest electrical load despite being the largest single-blower model in the range. A cabin control kit is required for installation and sold separately.
