systems such as the watermaker, ice maker, refrigeration system or engine room ventilation to the network to enable interactive communication straight out of the box.
Eberspächer offer boaters their EasyStart Web, a much improved version of their web based remote control unit enabling an owner, authorized guest or crew member to operate the yacht’s heating system from any distance via smartphone, tablet or PC. This system uses a permanently installed roaming SIM chip and integrated antenna for access to the strongest signal in each county. Payment is via a much more convenient annual subscription of just £22.50 per year, eliminating the need for previous versions of buying and replacing the SIM every time the credit was used up.
As for other major technical installations on new build or refitted yachts, HVAC manufacturers have had to adapt, change and innovate by coming up with products that have a reduced footprint, are lightweight yet robust enough to withstand the rigours of the sea, reliable, easy to service and cost-efficient to run.
Specialising in refit and retrofit work, Penguin Marine Refrigeration Sarl began
PENGUIN MARINE Former merchant navy captain, Phil Hooper formed Penguin Marine Refrigeration Sarl in Antibes in 1991, establishing a very high reputation over the following years. They supply and service all makes of marine air conditioning and refrigeration systems. Specialising in refit and retrofit work, they are official dealers and agents for most of the main manufacturers including Condaria, Marinair, Cruisair, Climma and have a close relationship with Frigit and Frigomar. Recently having completed a full air conditioning refit of a 480000 BTU soundproofed chiller on board M/V Odessa 1. Future projects include full refits aboard a 57M vessel and another on a 36M research vessel. For more details Tel: +33(0)493950696 or visit

life in Antibes in 1991 and was started by former merchant navy captain, Phil Hooper, who said: “In my opinion, the most significant change for HVAC over the last decade is the size of new vessels and the huge capacities now needed to efficiently cool these vessels.
“Clients have become more demanding and the focus is now more towards energy efficient products with, for example, inverter drives for better climate control, energy saving and reliability.”
Heinen & Hopman’s Eric van Dijk said: “In the early pre-engineering phase we aim to design technical spaces with fan air-handlers and vertical duct shafts in the centre of areas served by the units and fans. Advantages are smaller ducts, smaller air-handlers & fans, lower power consumption, reduced sound and weight saving.”
If we think of the chiller or compressor as the heart of a central HVAC system, it serves the temperature requirements of the yacht generally via an insulated loop threaded around the vessel and containing water, usually starting and finishing in the machinery space. Locally positioned fan coil units, or air-handlers, (often with supplementary heating units either outside or inside the water loop) deliver required temperatures to individual spaces or zones and it’s with chillers where we’ve seen the most innovation in recent years.
Heinen & Hopman claim their oil-free Turbocor Chiller can reduce energy consumption by up to 50% and take up half the space of a conventional chiller. The absence of oil means ‘extras’ such as oil heaters, pumps, separators or filters are not needed and it uses frictionless magnetic bearings for reduced noise and maintenance.
THE FOCUS IS TOWARDS ENERGY EFFICIENT PRODUCTS WITH INVERTER DRIVES FOR BETTER CLIMATE CONTROL, ENERGY SAVING AND RELIABILITY
