COMPACT HEAT EXCHANGER HE 60 - Especially adapted for liquids with solid content The coolers/radiators of the HE 60 series consist of coaxial heat exchangers, operated according the counter flow principle. They are completely made of steel. Chrome-nickel steel type 1.4571 (AISI 316) is used for all parts encountering with liquids. The exchangers have especially been developed for liquids with solid contents and are food safe. The spiral form helps to minimize pressure drop and allows the filling with semifluid substances for easy cleaning. The compact mobile apparatus is easily operable. The coaxial exchanger used is patent-registered. Additional profiles inside the secondary loop optimize the turbulence of the cooling/heating medium and increase the exchanging coefficient.
