Marine Air Conditioning
Mabru's 12V DC self-contained marine units deliver compact, efficient cooling for boats. Engineered with corrosion-resistant materials and advanced metering systems, they reduce battery strain while maintaining consistent cabin temperatures. Tested in Florida's harsh conditions, these systems ensure reliability for boaters worldwide.
RV Rooftop Units
Our 12V DC RV rooftop units provide quiet, generator-free cooling for motorhomes and vans. The low-profile design minimizes aerodynamic drag while delivering 12,000 BTU of cooling power. UV-resistant exteriors and lifetime compressor warranties make them ideal for long-term travelers seeking energy-efficient climate control.
48V DC Systems
The 48V DC series offers 17,000 BTU cooling for larger vessels with hybrid power systems. Designed for extended runtime and quiet operation, these units feature advanced airflow engineering and durable 70/30 copper/nickel condensing coils. Ideal for yachts requiring high-performance battery-powered climate solutions.
Battery-Powered Solutions
Mabru's DC systems optimize energy use through advanced compressor technology and digital controls. With amp draw ranging from 17-55A depending on model, our solutions maximize cooling efficiency while minimizing battery drainperfect for off-grid living on boats or RVs without shore power access.
Climate Control Systems
From 5,000 BTU compact units to 17,000 BTU commercial systems, we offer tailored climate control for marine and RV applications. Features include remote temperature sensors, stainless steel drain pans, and digital controls with network connectivity for seamless integration into any vessel or vehicle.
