The ETV model is a vacuum evaporator/concentrator with heat exchanger submerged in the fluid to be processed or, on customer’s demand, with an outer shell and tubes exchanger. Moreover, PF10 is the sole manufacturer of exchanger with submerged plates.

All PF10 evaporation plants can be manufactured in AISI 316 (std. version), duplex, super duplex, according to the characteristics of the fluid to be treated.

All PF10 vacuum evaporators have the following features:

• Automatic operation.
• Concentrate discharge by pump with automatic frequency can be set to PLC or by consent received from densimeter, which can be provided the evaporator, without stopping the operation of evaporation and without losing vacuum.
• Possibility of recycling the processed fluid
• Automatic antifoam system.
• Sightglass (with cleaning system) to control the contents of the tank.
• Chance of taking samples of the distillate and concentrate without deactivation of the plant.

The EDH model is an evaporator of high energy efficiency.

The power is supplied through a heat pump that employs a particular freon and exploits the thermal power of the fluid, evaporated during the first stage of evaporation, to supply a second stage of evaporation. This model allows to reduce the electric consumption of 40% than the similar single effect ETV model. The construction materials of this evaporator are the same as those used for the ETV and ETC models.

The ETD model takes advantage of the crystal precipitation when the solute overcomes the solubility limit. In order to obtain these outcomes, the plant has no submerged heat exchanger, but uses jacked exchangers to heat the fluids. The boiling tank is horizontal and the concentrate can reach the consistency of mud. The discharge occurs manually through the opening of the front hatchway.

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.
