In short
In 2019, we sold n.4 x PME 7204 E K19 Super Silent + WA + C to a Swedish pulp mill.
Super Silent” version of PME allows to respect the extraordinary low sound demands of the customer. “Super Silent” version involves a bigger footprint in comparison with standard version of PME, 16 poles motors and special blades shape.
16 poles motors and special blades allow a relevant decrease of the noise related to the motor-fan group. Water attenuators in basins (WA) and silencers on air inlets (“C”) decrease the noise related to the water falling in the basins.
By oversizing the unit, the required air flow and the pressure loss in the cool pack are decreased thereby allowing use of a smaller motor and at a lower speedl: this bring to another important advantage of the sold solution, that is a considerably lower power use in comparison with the standard model (approx. 50% less).
