A n effi cient and reliable HVAC (heating, ventila- tion and air conditioning) system on board com- mercial vessels is essential. In diffi cult and often extreme operating conditions, the system will provide a comfortable and healthy work environment for crew and also protect vital electronic equipment from overheating and potentially breaking down. Recently, Dometic Marine supplied chilled water air conditioning systems and en- gine room ventilation equipment for new Signet Maritime Corporation tugs – the Signet Arcturus (November 2013) and Signet Polaris (April 2014) – both built at Patti Ma- rine Enterprises, Pensacola, FL. This equipment included a 20-ton chiller, with supporting air handlers, engine room ventilation, and mist eliminators Dometic Marine, a division of the Dometic Group, is a global supplier of comfort systems and equipment for yachts and pleasure boats and a major supplier of HVAC, engine room ventilation, watermakers, and toilet systems to the commercial, workboat and military markets. This includes an extensive line of air conditioning systems to handle and suit a variety of vessels, from its high-capacity chilled water systems to its smaller self-contained systems.
