Marine Air's self-contained systems for boats up to about 12 meters (40 feet) feature the high efficiency Tecumseh rotary compressor for lower power consumption, quieter operation, lighter weight and increased reliability. Their award winning, self-contained model -- the Vector Turbo -- is 25% smaller than any comparable system, thanks to a patented design breakthrough that places the condenser coil inside the evaporator shroud. Our wide range of capacities and configurations allows designers, builders and owners to find the successful solution they need, within budget.
