USES The combined system of this buffer- production tank translates into a system to collect and distribute energy produced by various conventional or alternative sources, directly or indirectly, through fixed heat exchangers inside the buffer tank. The hot water required to supply the various types of thermal system is drawn from the buffer tank: at high temperature, if the water is drawn from the upper part of the buffer tank, or at low temperature for radiant floor heating systems if water is drawn from the lower part. In this system the preparation-storage tank for domestic hot water is inserted inside the buffer tank.
CONSTRUCTION Made of S235JR EN10025 steel sheet, assembled and welded with the use of automated systems in a controlled atmosphere. Fixed coil heat exchangers (according to the models) with S235JR EN10025 steel tubes welded to the tank.
TVEKB: buffer-production tank without fixed heat exchangers, preparation-storage tank for domestic hot water in enamel oated steel (EMAIL).
TVEKB-S: buffer-production tank with one fixed heat exchanger, preparation-storage tank for domestic hot water in enamelcoated steel (EMAIL).
TVEKB-SS: buffer-production tank with two fixed heat exchangers, preparation-storage tank for domestic hot water in enamel- coated steel (EMAIL).
ANTI-CORROSION TREATMENT Vitreous enamel interior (EMAIL), applied and baked at 860C according to the standard DIN 4753.3, suitable for use with water intended for human consumption in accordance with Ministerial Decree 174/2044 and Dir. 76/893/EC.
CATHODIC PROTECTION Sacrificial magnesium anodes on threaded cap.
INSULATION AND EXTERNAL FINISH Rigid polyurethane for models 220600 and flexible polyurethane for the remaining models; external finish in PVC closed with zip and thermoformed cover.
WARRANTY AND CERTIFICATION 5 years against corrosion
