PF10 Impianti Industriali products

The ETW model is a vacuum evaporator/concentrator with heat exchanger submerged in the treated fluid or, at customer’s request, with an outer shell and tubes heat exchanger. Alternatively, PF 10 can install special submerged plates heat exchangers. These vacuum evaporators/concentrators exploit during the evaporation phase the thermal power supplied by hot water or steam and for the condensation phase the one produced by water from closed circuit dry-coolers or evaporation towers.

The ETW DE model is an evaporator of high energy efficiency. These evaporators, as the ETW ME series, exploit the thermal power produced by hot water or steam (or diathermic oil) during the evaporation phase and the one produced by water coming from closed circuit dry-coolers or evaporation towers during the condensation phase. Moreover, the thermal energy produced by the condensate during the first stage is used to supply a second evaporation phase. This model allows, consequently, to reduce more than 40% of thermal energy consumption in comparison with the similar single effect model.

Among the vacuum evaporators/concentrators that exploit thermal energy powered by hot water or steam (or diathermic oil) during the first evaporation stage, the ETR W model has been developed to obtain more concentrated waste and to treat encrusting solutions. The employment of an automatic scraper, that keeps the exchange surfaces of the vertical tank clean, allows to obtain thicker concentrates than the ones got through other evaporation systems. The concentrate can be discharged either with a membrane pump or through a butterfly valve.

Crio Crystallizers are batch working units, that use the cooling technique to reach the solubility limit, separate the processed solutes, by obtaining solid crystals of waste. The cooling process creates saturation on the surface of the heat exchanger and the crystals are removed through an automatic scraper. The power used to cool the solution is supplied by a refrigeration system.

The Plant Division designs and builds plants for the treatment of water and gaseous streams, ultra- and nano-filtration systems for process fluids and waste water.
