Now if seems r404a is going out of the window for cold stores etc,what is the long term view for an alternative to it,and at what cost once I have my operation and j return to the industry it would be great to know what the views are,stockpiling is always on the cards which is bound to happen,the legal aspect of fitting new equipment running on r404a and its risks also interests me as most transport units are still made with r404a as a common refrigerant?
