6 7 DIFFERENT MATERIALS (AVAILABLE ON REQUEST) STANDARD CONFIGURATIONS SPECIAL CONFIGURATIONS Tubes Cu DHP CuNi 90-10, CuSn,SS AISI 304L, SS AISI 316L Fins Al – alloy 8006 Alupaint(*), Cu DHP, CuSn, heat exchanger painted after construction (Blygold, Heresite,…) Headers Cu DHP Fe (ASTM A106 gr B), SS AISI 304L (cylindrical header or openable header box) SS AISI 316 Casing Galvanized steel, powder-coated, RAL 9003 (C4 corrosion resistance) SS AISI 304L, SS AISI 316L (*)Alupaint: pre-polyester-painted aluminium strip capable of withstanding 1000 hours in salt spray test (ASTM B117). There are several alternatives to protect heat exchangers from corrosion, each of them designed for a specific environmental condition. In addition to thicker fins, there are solutions in aluminium-manganese alloy or copper fins and many surface treatments for the most severe conditions. PROTECTION FOR ALL ENVIRONMENTAL CONDITIONS Materials Fans FANDIAMETERS 800 - 910 - 1000 [mm] Fan-motors with external aluminum or composite material rotors. In this configuration the fan-motor is a single item and has several advantages: • compactness • excellent aerolic and electrical efficiency • lightness • easy replacement AC fan motors can be regulated with cut-phase controller or inverter. To achieve the highest energy efficiency, EC fans are recommended. Using more compact fans rather than few big-diameter fans enhances the reliabilityof the radiator, limiting loss of performance in the event of one motor failing. Surface treatments are available on request for these fan motors for severe environmental conditions. Axial fans are fitted, lubricated for life and balanced both statically and dynamically. Balance grade G6.3 (to ISO 1940 part 1). The protective fan grilles conform to the EN 294 Standard. FAN DIAMETERS 1250 , 1500 [mm] AND MORE Fan-motors with traditional internal rotors, directly coupled to the fan, generally constructed in PPG, PAG, Al. These motors can be supplied with different grades of mechanical and electrical protection to match every condition. For these motors, speed regulation can be obtained with inverter. In this configuration, the fan and motor can be adapted to the specific needs of the plant, maximizing heat capacity and reducing the footprint.
