Changing regulations

European Union

Under the Montreal Protocol (MP), the European Union member states are phasing out virgin HCFC (hydro chlorofluorocarbon) refrigerants with effect from 1 January 2010. It is prohibited to top-up a refrigeration system on an EU-flagged vessel using virgin HCFC refrigerants. R-22 is the most commonly used HCFC refrigerant in the maritime industry.

For EU-flagged vessels, it is still legal to use reclaimed R-22 obtained from an approved company within the EU to top-up and service systems until 2015. Buying virgin R-22 outside the EU after 1 January 2010 is a violation of the EU1005/2009 regulation.

Non article-5 countries

From 1 January 2010 a limitation on production and import of HCFC’s in the non article-5 countries was introduced. The yearly allowed production is now limited to 25% of the base level established in 1996.

United States of America

In the United States of America it will only be permissible to use virgin R-22 to top-up existing systems constructed before 1 January 2010. No construction of new systems utilising R-22 will be allowed.

R-22 changeover solutions

Evaluating capacity changes against the cost of doing the changeover, we recommend Unicool R-417A as the most economical solution for changing over existing R-22 systems and maintaining sufficient performance. However, a careful evaluation of each system should be made, in some cases a more expensive changeover solution should be selected. For these systems refrigerants like Unicool R-407C, R-422D, R-427A and sometimes R-134a are possible alternatives.
