The Moby Lines passenger ferry company decided to use Arkema’s Forane® 427A refrigerant fluid for a problem-free retrofit of refrigeration equipment running on R-22 on its OTTA ferry. R-22 is an HCFC type refrigerant fluid. Forane® 427A is a 100% HFC refrigerant blend that does not harm the ozone layer.

This retrofit operation brings Moby Lines into compliance with European regulations 2037/2000 which ban the use of the HCFC-22 virgin refrigerant for the maintenance of refrigeration systems, beginning January 1st 2010.

The retrofit operation was completed in the port of Genoa, Italy, by the contractor, Tecnoimpianti. In this case, the retrofitted system is a water cooling unit that produces cold water at a temperature of 7°C. The unit’s refrigerant charge is 400 kg for each STAL compressor (screw compressors). The system’s mineral oil was replaced with POE oil, and the R22 charge was replaced with an equivalent charge of Forane® 427A.
