Installation, Cabin Layout and Power Selection Criteria
- Check the exact Webasto BlueCool S13 and Mabru SC12DC model documents and voltage variants.
- Have the installer assess the occupied cabins, available equipment spaces and seawater flow.
- Compare complete installed costs, commissioning and local service support; equipment-only prices are not equivalent quotes.
A model comparison is only a shortlist. Before ordering, confirm the exact 240 V / 50 Hz specification, dimensions, minimum seawater flow, duct requirements and current manual with the manufacturer. Use the sizing pages to test the capacity against your boat, then read the official source list and advice limits.
