Webasto A12 BlueCool A-Series Slimline Air Handler – 12,000 BTU – 230V

Cabins with a narrow, tall installation bay needing 12,000 BTU of cooling get a purpose-built fit in the Webasto A12 Slimline Air Handler, delivering full A12-class performance in a vertical chassis designed for tight width constraints. This narrow bay chilled water unit trades footprint for height, standing 24.4 inches tall but just 8.50 inches wide.

This configuration solves a specific installation problem: a standard compact A12 needs floor or shelf space that a narrow vertical bay behind a bulkhead or in a tight closet simply doesn’t have, while the slimline chassis fits that same space by standing tall instead of spreading wide.

Why Choose the Webasto A12 Slimline

This unit carries Webasto’s standard 2-year warranty. If your installation bay is tall and narrow rather than wide and shallow, this slimline configuration delivers the same 12,000 BTU performance as the compact version in a chassis built to fit.

What to Know Before Installing

• A Webasto A-Series Cabin Control Kit is required for installation — this listing is the air handler only
• Measure your installation bay carefully — at 24.4″ tall and only 8.50″ wide, this unit needs more vertical clearance than the standard compact A12
• This handler requires a matching Webasto chiller (C-Series, V-Series, or VX-Series) as the central cooling source
• Can be extended with an EHM1200W electric heat module and flow control valve for independent cabin heating
