Refrigeration Optimising Performance

Pressure to perform. Constantly changing regulation. WSS takes the heat off. There are a few reasons why refrigeration systems demand special attention. The most obvious one is that they perform a vital function on board - maintain the correct temperatures for the preservation of cargo, provisions and providing a comfortable climate for passengers and crew. But beyond their primary purpose, keeping things cool, refrigerants and refrigeration systems are also subject to close environmental regulation. And those regulations change constantly. The challenge for shipowners and operators is to make sure their systems keep running smoothly, and that they remain fully compliant with all current regulations. WSS provides the complete refrigeration solution. We offer a wide range of high quality refrigerants, maintenance equipment and spares to keep your systems working at their optimum. The Unicool range of refrigerants is readily available worldwide through our global supply network and is supported by the highest level of technical knowhow. As the world s largest provider of marine refrigerants, we are fully conversant with the demands of environmental regulation. And we constantly look to the future to make certain that our products, and our customers who use them, remain compliant always.
Wilhelmsen Ships Service Marine Products Commitment to the environment. The next generation of refrigerants The world demands that refrigerants must change. Driven by international agreements intended to reduce global warming and limit ozone depletion, harmful refrigerant types are being phased out in favour of more environmentally acceptable solutions. R22 is already being removed from service and it s likely that R404A will follow. At WSS, we re at the forefront of these changes, testing new, environmentally friendly alternatives and helping customers adapt to the next generation of refrigerants, efficiently and cost-effectively. Keeping ahead of environmental regulation isn t just about using environmentally friendly refrigerants. Crucially, it s also about main taining the integrity of the refrigeration system. The most serious environmental impact from a refrigeration system over its lifetime is caused by increased energy consumption. Put simply, a leaking system is less efficient - a 10% loss in refrigerant increases energy consumption by up to 20%. While the costs caused by a leaking system increase steadily over time if the leak is not attended to, the actual cost of repairing the leak remains nearly constant. To keep your system free of leaks and working at its optimum we provide a complete range of tools, spares and maintenance equipment. A well-maintained system will help you stay within the boundaries of environmental regulation and keep your refrigeration costs down. Unitor Fixed Leak Detection Kit Provides effective round-the-clock monitoring and leak detection. Reduces the risk of environmental damage from accidental refrigerant loss. Helps protect crew from exposure to harmful refrigerant gas. This is Marine Products, done better. PAGE 04 / 05
R-22 Replacements R-22 being the most frequently used refrigerant over the past 3 decades, is being phased out due to its ozone depleting potential. But numerous ships using R-22 still have many years left in service, so a non-ozone depleting alternative to R-22 is required. There are between 25 and 30 different R-22 replacements to choose from, with different success factors, prices and availability. At WSS we recommend Unicool R-417A as the R-22 replacement in existing systems, after extensive testing of the available options. This is the fastest and cheapest way to replace R-22 in existing systems and maintain acceptable performance/capacity. So far more than 2,700 ships have been retrofitted from R-22 to Unicool R-417A. WSS has Unicool R-417A available globally in both large and small cylinders. Other non-ozone depleting R-22 replacements are offered out of selected ports and in large cylinders only; these refrigerants are Unicool R-427A and Unicool R-422D.
Wilhelmsen Ships Service Marine Products The difference is in the delivery. Quality guaranteed While cheaper refrigerants might seem like a cost-saving option, in most cases you re charging the system with problems. Refrigerants contaminated with moisture cause corrosion in compressors, leading to a loss of operating efficiency and costly mechanical breakdown. It s better to be sure. With Unicool refrigerants, the quality and minimum moisture content of the gases is guaranteed, so removing the risk of damage to equipment or harm to crew caused by poor quality refrigerants. What s more, Unicool cylinders are filled and sealed only by approved suppliers. Good to know. Cylinder safety and maintenance Before filling, every cylinder is inspected according to strict rules by trained technicians and where necessary refurbished and re-qualified. Those that fail to meet our standards are scrapped, so there s no doubt about the integrity of cylinders or concern about the consequences of failure. We go further. Every Unicool cylinder is covered by insurance to direct damage due to cylinder failure while on board. We take responsibility, which means peace of mind for you and greater protection for your vessel, your crew and port personnel. UniTrak global track and trace With UniTrak, we ve made it easier to take control of cylinder stocks. UniTrak is a unique track and trace system that supports the delivery and exchange of Unicool cylinders worldwide. Every cylinder is logged on the system and customers are given direct access so you can view cylinder stocks online - any vessel, any time. Cylinder numbers, filling schedules, delivery locations - all information is available to help you manage cylinders accurately, costeffectively and securely. PAGE 06 / 07
the worlds leading maritime network Complete compliance WSS s cylinder exchange service conforms fully with the rules set out in the ISPS Code which requires close monitoring of the movement of high pressure cylinders. This is made possible by our UniTrak global track and trace system. Throughout, we are committed to providing the most environmentally friendly solutions. In practice, this means that our gas products and our services comply with all international regulations for the reduction of global warming and the prevention of ozone depletion. Because we stay compliant, you stay compliant. And when regulations are revised, we work to make sure you stay ahead of the changes. Availability The WSS network provides a global service for the delivery, exchange and maintenance of Unicool refrigerant gas cylinders. Which means that refrigerants are always available for re-supply wherever your vessels are in the world.
