DOMETIC Dometic has the ability to air condition boats from 8m to 80m+ and works alongside partners on even larger projects. With decades of experience in the sector, Dometic recognises that supplying air conditioning solutions for the luxury superyacht market requires industry leading technology, continual innovation and the highest performing climate control systems because the expectations of the clients, designers and boat builders are so high. The focus continues to be on answering the demands from builders and consumers for reliable, quiet systems and less energy consumption in the smallest possible package. For more details visit

HVAC is expected on boats of a certain size as an integral part of their design, with climate control simply part of usual life onboard for captain, crew and guests. In the same way that air conditioning is now the norm in the automotive sector and no longer highlighted in brochures anymore, this is now true for larger boats.”
Hickinbotham adds, “We work with the majority of boatbuilders, often collaborating with them on concept designs directly to engineer specific spaces for the equipment. Behind the scenes, our teams are supplying the complete systems for boat builders as a standard service, installing everything including complete seawater circuits, copper refrigeration circuits, ducting, ‘drains n all’.”
Synergy is a newly formed HVAC systems and energy management company. Headed up by Patrick Voorn, an HVAC consultant with over 15 years in the maritime and offshore industry, he is backed by a team with more than 25 years of cumulative experience and expert technical knowledge behind them. Voorn believes that when it comes to HVAC the main talking points revolve around energy savings and air quality. He says, “The yacht’s HVAC system is the biggest energy and space consuming system onboard.” With over 50% - 60% energy reservations on the total E load balance in every situation, whether it is in port, at anchor, crossing an ocean or cruising from one anchorage to another HVAC is always the largest energy consumer.”
Currently the reduction of greenhouse gas emissions is a topic in all sectors of the industry and the yachting industry is no different. This was the reason the IMO came up with an action plan calling for a 50% emission reduction in 2050. Reduction of CO2 emissions in ships can often be achieved by reducing propulsion power, but the average superyacht propulsion unit is only employed between 17% and 25% of the time while HVAC is used 100% of the time.
Voorn says, “This means we must seriously take a look at the reduction of auxiliary power consumption.” He adds, “It is a logical step from air cooling towards air treatment keeping control of air quality. Cooling outside air can run up to 75% more cooling energy compared to cooling recirculation air. By cleaning and treating your recirculation air you will be able to save energy without losing the high level of air quality. Creating awareness among the onboard engineers and crew needs be the first step in this process.”
BY CLEANING AND TREATING YOUR RECIRCULATION AIR YOU WILL BE ABLE TO SAVE ENERGY WITHOUT LOSING THE HIGH LEVEL OF AIR QUALITY NEEDED
What’s new? Earlier this year Dometic announced that it had extended its titanium condensers to its line of Variable Capacity or VARC chillers, combining the use of industrial-grade titanium with variable speed technology. This means that the new titanium VARCX offers all the efficiency benefits associated with the VARC chiller line, plus the condenser coils made of titanium make the units virtually immune to erosion and corrosion, significantly extending the life of cooling systems.
Hickinbotham said, “The use of titanium is a ground-breaking development for chiller longevity in the marine industry, providing boaters, captains and boat builders with a vastly more corrosion- resistant material. Titanium is a very strong material that does not erode easily and therefore makes robust and long-lasting condenser tubes for vessel chillers.”
System efficiency is now very high on every Chief Engineer’s radar as it leads to less load on the engines, more reliability and easier fault diagnosis. The advancements in system performance analysis are showing great rewards. Stuart Ginbey the Managing Director of Tradewinds Engineering Ltd says, “Our computer based
