Cost-effective R22 refrigerant replacement

After performing in-house tests, Wilhelmsen decided on Unicool R-417A as a cost-efficient option for replacing R-22 in direct expansion systems across a variety of applications. However, although Unicool R-417A is suitable for customers that prefer to use a single alternative, there are several operating vessel types (such as passenger ships) that call for optimal performance in a variety of large cooling system applications. In order to stock the ideal replacement alternative for each system, some customers need to carry several different types of refrigerants onboard.

Acting on such requests Wilhelmsen Ships Service has expanded its range to include Unicool R-422D (ISCEON® 29 by DuPont) and Unicool R-427A (FORANE® by ARKEMA). For customers who now have different refrigerant types on board the same vessel, all Unicool cylinders are colour-coded and labelled to lessen the risk of charging the wrong gas.
