Frequently Asked Questions

Discover answers to frequently asked questions about our vacuum evaporators on this page.

With an IWE energy-efficient vacuum evaporator, the volume of wastewater destined for disposal can be reduced by up to 95% or more with minimal operating costs. This is because under vacuum conditions we are able to evaporate the wastewater at low temperature obtaining a distillate (which can in many cases be reused for different purposes) and a minimum amount of concentrate. The economic advantage generated by the reduction of disposal costs is obvious, but equally important is the reduction of environmental impact.
It should also be considered that all IWE vacuum evaporators comply with "Transition 4.0" requirements and enjoy significant tax benefits.
IWE vacuum evaporators can be used in many sectors of activity as the vacuum evaporation technology allows the treatment of a wide category of wastewater.
We have installed evaporators in the following industries: Metalmechanical, Galvanic, Die-casting, Agricultural (digestate), Food, Waste Treatment Platforms (landfill leachate), Chemical, Pharmaceutical, Rubber Vulcanization, Heat Treatments, Industrial Painting and also Grape must and balsamic vinegar concentrates or natural flavors and herbal extracts.
In general, IWE vacuum evaporators can treat any type of industrial wastewater containing different types of pollutants that is normally destined for disposal.
The brand name "IWE EVAPORATORS EASY CLEANING INNOVATIVE TECHNOLOGY" indicates the innovative solution conceived by IWE to facilitate the cleaning and maintenance of heat exchangers.

IWE EVAPORATORS EASY CLEANING INNOVATIVE TECHNOLOGY is the name of the innovative solution conceived by IWE to facilitate the cleaning and maintenance of heat exchangers. In fact, IWE does not use traditional shell and tube or coil heat exchangers, but a special "immersed plate" system which, thanks to the large free spaces between the plates, allows extremely simple and fast cleaning operations.
. This greatly reduces the downtime required to restore maximum efficiency of the evaporator after the onset of fouling.
First of all, we analyze the "status" of your wastewater treatment and disposal situation.
In this phase we carry out a briefing to obtain three fundamental data: volume of the wastewater, nature of the wastewater (laboratory analysis), possible availability of energy sources (cogenerators, hot water or steam).
On the basis of this information we are able to hypothesize the optimal results achievable with a specific model of evaporator. At this point we propose the development of an "onsite" test session with our pilot plant to validate the predicted performance.
Once the tests have been completed, we move on to the design and realization phase of the plant on an industrial scale.
We support the customer in a constant and personalized way with specific after-sales maintenance packages. Thanks to the remote control function we are able to intervene in "real time" by connecting to the evaporator from our headquarters to check the operating parameters and identify any anomalies.
The evaporator operates in fully automatic mode 24/24 - 7/7 and does not require the presence of a dedicated operator.
