Pressure controlled fan / EC fan
Available with heat recovery
Mainly manufactured from stainless steel
4 drain connections
MAR-IX fresh-air ventilation systems are equipped with a pressure-controlled fan that ensures the volume of emitted air remains constant at all times. The fans keep the air in the vessel at a slight overpressure so that warm or cold air will not enter when a door is opened. The system is self-adjusting should the air filters become polluted. The dimensions of the MAR-IX ventilation units are extremely compact and the units are mainly manufactured from stainless steel.
Save your energy
MAR-IX fresh-air units are equipped with a heat recovery system which reuses up to 60% of the energy of the extraction air. This inventive solution reduces the cooling and heating capacity so that you can fit smaller chiller units and heaters. What’s more, a smaller generator can be used to further lower costs. A ventilation system with heat recovery function consists of two units. The supply unit (FAM) filters the incoming air through a built-in High Air Flow (HAF) air filter and F9 filter. The fresh air is then acclimatised and dehumidified before being blown into the vessel with a slight overpressure. Dirty air from the cabins, showers, toilets and other spaces is removed by an extraction unit (RAM). The fresh-air supply unit and extraction unit are connected by a liquid pipe and with liquid used for energy transport there is no mixing of air.

All MAR-IX fresh air systems are equipped with a pre-filter and a F9 fine filter, providing you with an optimal level of air quality. Our standard ventilation systems have an output from 100 m³ to 5,000 m³/h. Units can be equipped with a cooling, heating and heat recovery battery, as well as electric heating elements. Custom-built units with larger capacities are always available as we merge our expertise with your requirements.
