Description
Webasto BlueCool S20 230V Unit
The Webasto BlueCool S20 (230V Variant) deploys a space-saving remote framework engineered to supply a powerful 20,000 BTU/h heating and cooling solution directly to localized master staterooms up to 1,000 cu.ft. The heavy-duty 14.2×20.5×15.0-inch structural chassis installs remotely within narrow bilge locations, pumping conditioned air smoothly at 470 CFM through a 6-inch duct connection to prevent hot spots. This modern configuration delivers exceptional thermal regulation on complex international hulls, providing the ultimate choice to function as an integrated NMEA 2000 marine HVAC infrastructure network layer.
Operational safety on a single-phase 230V 50/60Hz electrical infrastructure is secured by an integrated hermetic scroll / heavy-duty rotary compressor pulling a continuous 6.5A cooling current and a 7.4A heating current draw while managing a 34A locked rotor startup surge. The 77.2 lbs indoor assembly utilizes a rugged extra-deep composite condensate tray paired with premium cupronickel condenser coils, holding mechanical machinery vibration sound emissions down to an absolute minimum. External seawater plumbing lines link directly to 5/8-inch pipe hardware, finishing an IP22 protected build fully matching an elite, 230v chilled water fan coil alternative layout.
Technical Capabilities and Attributes:
- High capacity twenty thousand BTU compact self contained system layout
- Extra deep composite condensate tray completely eliminates internal bilge rust
- Premium cupronickel condenser coil prevents severe raw water oxidation damage
- Heavy duty structural frame stabilizes crowded compartment installations smoothly
- Nominal 6.5A cooling running current draw profile cuts load
- Hermetic scroll compressor mechanism limits localized cabin vibration sound
- Standard 5/8-inch seawater inlet and outlet plumbing connections size
- Universal 230V framework adapts to international yacht generator grids
- Rigid thirty five kilogram structural chassis ensures stable mounting
- Pre charged eco conscious R-410A structural refrigerant loop tracking
Alloy Thermodynamics and Dissipation
Cupronickel condenser coils provide maximum thermal transfer across all high-temperature seawater circuits by optimizing heat absorption boundaries. The self-contained core matrix balancing allows real-time capacity control adjustments, matching fluctuating onboard environments while protecting sensitive line pressures against sudden climate drop-offs. This heavy-duty mechanical architecture ensures continuous raw water flow, sustaining reliable off-grid thermodynamic limits during extended luxury cruising.
Comprehensive Manufacturer Coverage
A comprehensive 2-year factory warranty protects all structural plant parts, mechanical core modules, and electronic staging components against defects under standard marine operating protocols. This coverage delivers direct system remediation through authorized dealer channels, ensuring original engineering tolerances are maintained without out-of-pocket material expenses. Vessel owners enjoy peace of mind knowing mechanical and electronic infrastructure elements are fully secured.
Vessel Layout Fit
Vessels measuring 36-45ft achieve ideal climate stability using this compact high-output marine climate control configuration. The industrial grand salon framework fits cleanly into expansive master staterooms or multi-cabin environments requiring a minimal 4.5 kW auxiliary generator footprint. Proper hardware optimization balances continuous moisture extraction across your dedicated ducting lines, allowing operators to maximize layout space while reducing equipment strain.

Webasto S20 Marine AC FAQ
What are the electrical requirements for S20?
Webasto S20 operates safely on a 230V power supply. This single-phase network installation draws minimal running current, allowing long-distance coastal cruisers to distribute climate loads smoothly over international shore lines or standard diesel generator panels without throwing primary distribution breakers during high-load summer periods.
What airflow volume does this system deliver?
Webasto S20 generates an airflow volume of 465 CFM. The integrated rotatable high-velocity centrifugal blower fan operates dynamically to flush hot humidity profiles from cramped living spaces while keeping system resonance decibels extremely low against lightweight composite structural hull partitions and marine plywood cabin walls.
Which vessels fit the Webasto S20?
Webasto S20 is designed for mid-sized cabins and crew quarters. It provides optimal cooling coverage for sailboats and motor yachts ranging from thirty-five to forty-five feet, delivering efficient climate regulation underneath bunk spaces or within designated cockpit lockers without taking up crucial living space.
