Some people wonder whether wine sulphites can cause corrosion and perforate the refrigeration system. The answer is NO. It is totally FALSE to claim that sulphites perforate the evaporator piping. You should understand that if the sulphites can escape from the bottle, air can also get in. Evaporators that are pierced after 1 to 3 years generally are of poor quality. The pipes may also be thinner than 14 thousandths (see Photo A). Rosyma's evaporators are 26 thousandths thick (see Photo B). Because aluminium is subject to premature corrosion, Rosyma uses copper pipes, which have a useful life of several years.

When you shop for your cabinet, Rosyma suggests you ask to see the refrigeration system. If it is inside the cabinet walls, you should understand that it will be impossible to replace later if corrosion develops.
