Werkstoffe: Khlerblock: Aluminium Ventilator: Kunststoff Sonstiges: Stahl, galvanisch verzinktMaterials of the filters acc. to 5 (system sizes 0 - 0): Housing: GK-AL Filter element: Cr Ni St and ALSeals: Perbunan Materials of the filters acc. to 5 (system sizes 0 - : Housing and change-over element: GG 2 Bell housing: GK-AlFilter element: Cr Ni St and Al Seals: Buna Materials of differential pressure monitors: Housing: Al Si 1 Medium-contacted housing parts: Al Si 1 Seals: Buna Water-oil coolers (for type OW..) part no. 3 The water-oil cooler is heat exchanger operating with low pressure loss. It has highly effective additional surface consisting of copper lamellas which are pushed over the entire pipe assembly. These lamellas are in metal-to-metal contact with the pipes. The oil is guided over the heat exchanger surface through segmental baffles. Technical data: Operating temperature: max. 1 Pressure through the pipes (water): max. 8 bar Pressure around the pipes (oil): max. 1 bar Design: resistant to brackish water Materials: Housing: Al Water chambers: Cu 8 Sn Zn Pb Tube plates: Cu Zn 3 Sn 1 Tubes: Cu Ni 1 Fe Lamellas: Cu -rings: Viton Feet: St Air-oil coolers (for type OL..) part no. 3 acc. to Flender Works Standard 5 The air-oil cooler serves for cooling the oil, the ambient air serving as coolant. Depending on the volumetric flow, the oil is passed through the cooler in single or multiple flow, and is cooled by the ambient air fed by the fan.
