Wilhelmsen provides comprehensive refrigeration solutions, ranging from high-quality refrigerants, maintenance equipment and spares to keep your systems working at their optimum.

There are a few reasons why refrigeration systems require special attention. The most obvious one is that they perform a vital function on board - maintaining the correct temperatures for the preservation of cargo and providing a comfortable climate for passengers and crew. But beyond their primary purpose of keeping things cool, refrigerants and refrigeration systems are also subject to close environmental regulations which are ever-changing.

The challenge for ship owners and operators is to make sure their systems keep running smoothly, and that they remain fully compliant with all current regulations. With our wide range of high-quality refrigerants, maintenance equipment and spares, your systems will always be running optimally.

We have suffered in the past from low-quality refrigerants with high moisture content. This has resulted in clogged and broken down systems, and throwing away provisions due to high temperatures in the freezers. Low-quality refrigerants is not an option for us.
