MAR-IX airco inverter chiller units

MAR-IX inverter chiller units are designed in such a way that all refrigeration components are placed in a stainless steel casing. This ensures sound reduction and protection of the chiller against tough conditions in an engine room or other technical space. A major advantage of the compact design is that the chiller occupies little space. 

The MAR-IX AIV series chiller units are equipped with inverter compressor technology which means that the chiller will not switch the compressor on and off, but varies in speed to control the cooling capacity. By using this inverter technology, current peaks belong to the past and the electric system on board the ship will not be disrupted. It is standard that AIV chiller units are suitable for the most common power supplies, and will function on 50 as well as 60Hz. 

All units are equipped with a seawater-cooled condenser made of copper/nickel. Optionally available is a high efficient  condenser that can be connected directly to a box cooler. 

The AIV series chiller units can be connected to all MAR-IX fan coil units and controlled by our electronics with or without communication. If the AIV chiller is connected to the MAR-IX communication system, the chiller will also adjust its
cooling capacity to the actual need. The chiller will not supply more cooling capacity than what is needed, which unburdens the electric power consumption.

MAR-IX Fresh Air (Ventilation) Systems

Mavé is the only company in the world that has introduced a ventilation system that fully meets the requirements on board ships.

The materials used are resistant to the harsh conditions and salty air on board. The unit sizing is so compact that it can be applied on all ships. In addition, fresh air units can be equipped with a heat recovery system; a system which reuses up to 60% of
the energy of the extraction air. This means that the required capacity is lower, and therefore that a smaller chiller or heater will suffice. Subsequently, a smaller generator can be used, which reduces costs. 

A ventilation system with heat recovery function consists of two units. Firstly, a supply unit that emits fresh, filtered and conditioned air into all areas, and secondly a return unit that extracts air from toilets and wet areas. Residual heat (energy), which is normally discharged outside, will be used by the unique heat recovery system to pre-heat or cool the
fresh air in the supply unit. 

The systems are equipped with a pressure controlled fan. The use of pressure controlled fans ensures that the volume of emitted air always remains constant. The pressure controlled fans keep the air in the ship at a slight overpressure, so that warm air will not enter the ship when a door is opened. The system is self-adjusting in case the air filters pollute.

All MAR-IX fresh air systems are equipped with a pre-filter and a F9 fine filter, which will result in the most optimal air
quality. Mavé delivers standard ventilation systems with an output of 100m³ up to 5.000m³ /h. Units can be equipped
with a cooling, heating and heat recovery battery. Instead of the heating battery, the customer can also opt for electric
heating elements.

Mavé also offers the possibility to produce custom-built units with larger capacities.

Energy saving HVAC systems

The sustainable approach of MAR-IX marine HVAC systems
The company Mavé in The Netherlands is manufacturer of and specialized in customized marine HVAC systems, known under the brand MAR-IX. In general HVAC (Heating, Ventilation and Air-Conditioning) is one of the major energy users on board. Mavé is very much aware of the energy consumption of HVAC systems on-board (super)yachts and professional vessels, but also of the importance of keeping the operational costs and the pressure on the environment low. With this in mind the MAR-IX system developments always focus on energy saving solutions.

The most eco-friendly marine HVAC system in the world.
By using the MAR-IX marine HVAC system, several superyacht shipyards have already reduced the electric load of their HVAC system massively. In some cases the e-load reduction has been over 70% in the HVAC system and over 30% in the general electric load of the yacht. These remarkable results are the effect of smart product- and system engineering as well as using the newest available techniques. MAR-IX claims to be the most eco-friendly marine HVAC system in the world.

Once a vessel is able to reduce massively on its electrical power usage, it means an enormous improvement for the environment. Generators can be chosen smaller sized or do not have to produce so much power, which results in burning less fuel and by that less air pollution. Also the use of shore-power will be reduced. All these aspects certainly have a positive impact on the environment. But not only the environment is the winner, the benefits for the owners are interesting as well. Not only the building costs of a vessel will be reduced, but also the operational costs will decrease massively.

Reducing operational costs
"The awareness of reducing the operational costs of a vessel is not only something which is a point of attention on professional vessels, but we've noticed over the years that also superyacht owners and their crew are on top of their operational costs. By easily saving so much money on their operational costs, they are very motivated to have our low energy consuming HVAC systems installed," according to Mark Vermetten, CEO of Mavé.

Size matters ...
MAR-IX systems are well known for their small size, low sound levels  and excellent quality.
"Our in-house design- and engineering department is able to create highly energy efficient systems, especially when we are being involved in the projects from a very early stage on. Our company can then advice the yards with the best possible piping and ventilation routes through the vessel. This can save the yard a serious amount of money on installation costs." Vermetten says.

Related to other products available in the market for 25+ meter vessels, the amount of space which is saved by installing MAR-IX equipment is very interesting. "In case of a refit, the MAR-IX chillers are often less than half the size of the chiller plant originally installed; the same goes for our fresh-air systems.  Added to that, smaller sized systems also result in weight reduction, which is always an important aspect for vessels. With having smaller equipment, such as fan coil units that are usually placed behind the interior, we are able to offer the interior designers and shipyards more living space to work with; a real benefit." Vermetten explains. All these advantages together, combined with extremely low sound levels of the equipment, are the main reasons why MAR-IX products and systems are often chosen by super yacht shipyards and owners.

100% circular: recycling included
On the METSTRADE (Marine Equipment Trade Show), the world’s biggest B2B leisure marine equipment show, Mavé will present not only their newest MAR-IX innovative products, as well as their sustainable approach. One example of this approach is the offer for recycling removed units to refit clients. If we can install a MAR-IX system, Mavé will take care of the recycling of the removed chiller plant and other HVAC equipment. Vermetten: "By providing this service to our clients we are really on top of the circularity, we're not only talking about the environment, we also take care of it.”
