The tank has been carefully studied in order to be the very smallest possible. If compared to a traditional machine the capacity of the tank of TDS series has been reduced to one-tenth of what it was. A huge series of benefits outcomes thereof.. Tank's installation into the foundation is no needed any more. The tank in the new TDS series is placed on the top directly next to the cylinders groups and to the corresponding valves. This grants the pumps a slight over-feeding pressure which lenghtens their life and endurance considerably. First of all, at the first filling, 90% of oil is spared if compared to the traditional machine, the same is true as per the following periodic oil replacements. Thanks to this considerable oil saving oil replacement will be no more considered as an unbearable cost. Less of oil in the tank means that also the risk of a possible fire is prevented. In this respect the TDS series has been arranged in order to be able to work using non-flammable, synthetic and up to 400°C self-extinguishing, oil. Such characteristic is enough to avoid being obliged to arrange for the fire-fighting plant.
In traditional machines the huge quantity of oil permits the exploitation of its huge mass as a 'thermic lung”. The TDS series for such reason has been equipped with a series of efficient oil-water heat-exchangers for its thermic conditioning, working by tower water at the temperature of 30°C. It is also equipped with a continuous 10 micron filtration system. The system thus conceived permits the use of the oil for very long periods. The oil replacement is suggested every 45’000÷50'000 machine working hours.
