Expertise and experience are absolutely indispensable for the design of a safe, cost effective, and energy efficient large-scale industrial refrigeration system to which high standards apply, especially if a blast freezing unit or freezers and chillers are planned.
There are no “standard” refrigeration systems. Each time, the new ideal combination of equipment & suppliers needs to be found in order to design the best and most energy efficient system. Also, the ideal refrigerant will differ in each specific situation and can either be ammonia, freon, CO2, other natural refrigerants or a combination.
