Mavé BV is specialized in customized marine HVAC installations for superyachts and professional vessels. Our innovative HVAC products and systems, known under the brand name MAR-IX, offer perfect conditions on board in combination with maximum energy-efficiency and durability.
In general, HVAC is one of the major energy users on board. As a manufacturer of these systems, we are aware of that fact and our goal is to lower the overall energy consumption and with that the pressure on the environment. With having a significantly lower electrical load than other HVAC systems, we can offer a much more sustainable HVAC system with the advantages of reduced operational costs and a smaller environmental footprint.
Our in-house engineering department focusses constantly on the most sustainable configuration of the HVAC system. One of the keys for this achievement is the integration of other thermal energy users and producers. By intelligent system design, we achieve extraordinary results in terms of electric load reduction of the entire vessel. With the use of our ‘standard’ HVAC equipment, we offer already an electric load saving of 30% compared to other systems. But with the integration of our Hyper Thermal Process (HTP) we offer our clients up to 80% energy reduction on the hotel load on board!
With this saving on electrical load, the benefits for shipyards as well as shipowners are very interesting. Smaller sized generators are sufficient, this could save large and expensive SCR systems, and of course this will reflect in the reduction of fuel- and shore-power use.
The casings of MAR-IX products are mainly built from stainless steel, one of the most environmentally friendly materials. Stainless steel is corrosion resistant and durable, has a high-recycled content and recapture rate, and provides long service life and reduces resource use.
MAR-IX products are fully designed and manufactured in our modern factory in The Netherlands, our zero-energy facility is fully operated by renewable solar energy. We manufacture and test each system extensively and completely independently; we can control the entire production process. Accurate project management and a precise production planning ensure the achievement of on-time deliveries.
During refits we offer our clients the possibility to recycle the removed HVAC equipment; this service we offer free of charge. By providing this service we are really on top of circularity and durability.
We are proud to say that MAR-IX is the most eco-friendly HVAC system in the world.

Why Mavé supports Water Revolution
“Our innovative marine HVAC systems, known under the brand name MAR-IX, offer perfect conditions on board in combination with maximum energy-efficiency and durability. We are involved in both new-built and refit projects, where we always have a focus on the most sustainable configuration of the HVAC system. With our intelligent system design, we achieve extraordinary results in the reduction of electric hotel load on board. This results in a lower carbon footprint as well as in the reduction of building costs for the shipyard and operational costs for the yacht owner. Benefits for all parties involved as well as for our environment! As CEO of Mavé BV, I am very proud to say that we support Water Revolution Foundation in their aim to neutralise the yachting industry’s environmental footprint and preserve the world’s precious oceans. As a partner of the foundation, our drive is to add value to the industry by sharing our knowledge about using and producing thermal energy and to provide systems which help to reduce the carbon footprint of yachts.”
