Indeed, the boiler tank is able to meet simultaneous demands for hot water. The boilers are constructed entirely from low carbon chromium nickel molybdenum austenitic stainless steel (AISI 316 L), using cutting edge technology production processes to retain the high performance features of the raw material used. Once the process of working it has been completed, each product undergoes a pickling treatment followed by passivation, a step which is essential to maintain the steels high corrosion resistance. The production range comprises 6 models with water capacities from 200 to 500 litres, with and without the flange.
