VACUUM EVAPORATORS
The
product to be distilled is sucked into the evaporator exploiting the depression inside the
boiler, generated by the vacuum circuit. The cooling cycle, equipped with a heating pump,
is able both to get heat the liquid in treatment and to cool the vapours produced in the
boiling phase.
Strong point of this technology is the low running cost of its application. The vacuum
distillation, combined with heating pump, allows us to separate the water from the
polluted products at a low consumption of electricity.
EVAPORATORS
WITH INTERNAL EXCHANGER
- low energy consumption
- good concentration of the process residue
- limited dimensions
- for not encrusting products
- for emulsions of water and oil with concentrations lower than 20%
- typical application in diecasting and industrial degreasing
- versatile plant for almost any kind of product
- the scraper supports the thermal exchange and the concentration of the residue, avoiding encrustation on the heating surface
WITH EXTERNAL EXCHANGERS
- big hourly production
- low sensitivity to foam formation
- limited dimensions
They are utilised for big daily quantities and they are suitable for :
- concentrations till 20% of suspended solids
- concentrations till 1,25 kg/litre of density
For a higher concentration, they can be combined with an auxiliary plant, after the treatment, equipped with an inner scraper
