Spray-Chillers (Irrigation evaporator)
-Low quantity of refrigerant
-High specific cooling power
-Good protection against freezing up, as the pipes are not submerged in the refrigerant
-Integrated liquid separator
-Power range approx. 500-5000 kW
Picture: A total of 12 spray chillers are used in a polypropylene production plant at Geleen in the Netherlands. The cooling plant was installed by Sabroe, and has a total power of 25 MW.
Because it was possible that, in the event of a fault, hot water (90°C) would reach the apparatus, a design based on hairpin bundles was selected, in which unacceptable thermal tensions cannot develop. Because the inner pipes are not submerged in the refrigerant, there is again no need to fear that boiling will occur in the apparatus.
