If using the heat exchanger with temperatures over 100 C, ask for steam seals TYPE THICKNESS DENSITY INITIAL CONDUCTIVITY (*) LOSS EXTERNAL FINISH 6,53 kwh / 24h Flexible. expanded polyurethane with open cells kg/m 3 39 mw/m K 7,15 kwh / 24h 9,18 kwh / 24h Skay white RAL ,27 kwh / 24h (*) Thermal loss calculated with an accumulation temperature equal to 60 C and with an external temperature equal to 15 C. SAFETY DEVICES The cylinders must be protected against the effects of over pressure by installing: A SAFETY VALVE calibrated to pressure below the max pressure of the cylinder A SANITARY EXPANSION TANK mod. ELBI D DV series RECOMMENDED SANITARY EXPANSION TANK (mod. ELBI D-DV series) DV 150 DV 150 DV 300 n 2 pcs DV 200 Sized using the following parameters: T. accumulation= 85 C / T. inlet = 15 C / Pre-charge pressure = 3 bar / Max pressure = 6 bar The recoended capacity must be verified on the basis of the actual dimensions of the system implemented.
