Evaled RV

Product catalog summary

Overview
EVALED™ RV offers a range of mechanical vapor recompression (MVR) and forced circulation evaporators designed for industrial wastewater treatment. These systems are ideal for handling large quantities of waste that may cause fouling, precipitation, and crystal formation. The low running costs of these systems often result in a quick return on investment.

Environmental Commitment
VWS Italia is committed to reducing CO2 emissions and offers customized Carbon Footprint Assessments.

Materials
The evaporators are constructed using materials selected for their resistance to corrosion, essential for managing aggressive liquids. Key materials include:

Austenitic Stainless Steel AISI 316L: Suitable for alkaline and acidic liquids with low chloride content.
Superduplex Stainless Steel: Ideal for acidic liquids with high chloride and metal content.
Nickel Alloy: Used for very acidic liquids with high chloride, fluoride, and metal content.

EVALED™ TC Series
The TC series utilizes forced circulation technology with an external shell&tube heat exchanger, allowing high waste concentration and reduced maintenance. It is suitable for industries such as mechanical, surface treatments, power, and landfills. Models range from TC 10000 to TC 120000, with low specific energy consumption of 0.050 kWh/l distillate.

EVALED™ MVR Series
The MVR series employs a falling film heat exchanger for preconcentration, followed by forced circulation for further concentration. It is suitable for mechanical, chemical, and biogas industries. Models include MVR 100 and MVR 200, with energy consumption ranging from 0.025 to 0.030 kWh/l distillate.

Features and Benefits

Service: Includes maintenance, spare parts, and chemical products.
Value: Reduces disposal costs and enables water reuse.
Responsibility: Focus on low carbon and water footprint.

Technical Reports EVALED™ RV VWS Italia, in co-operation with respected materials research centres, selects the most suitable materials for the safe management of aggressive liquids. The resistance to corrosion is the main feature of every EVALED™ evaporator, essential when dealing with extremely concentrated liquids. Austenic stainless steel AISI 316L (Number: 1.4435 – X2 CrNiMo 18-14-3) Austenic weakly bound structure, non-hardening, non-magnetic. The low percentage of carbon in this alloy reduces the risk of intergranular corrosion at high temperatures. Uses: alkaline liquids, acid liquids...

EVALED™ TC Series TC series is based on forced circulation technology through an external shell&tube heat exchanger. The evaporator allows high levels of waste concentration and dramatical reduction of the frequency of cleaning and maintenance operations. Furthermore the high liquid recirculation through the tube heat exchanger allows an high heat exchange efficiency and a reduction of deposits or scaling on the heating surface. TC series is the best solution for: mechanical industry surface treatments power landfills Low specific energy consumption: 0.050 kWh/l distillate A standard structure:...

EVALED™ MVR Series MVR evaporator is based on the forced circulation technology through a falling film heat exchanger. It operates in two stages both having independent mechanical vapour recompression system: falling film followed by external heat exchanger. The falling film stage carries out the preconcentration of the solution, while the forced circulation with external shell&tube heat exchanger concentrates up to 30% of the total dissolved solids. The distillate is continuously produced and discharged by both stages. The main benefit of the falling film technique is the possibility of treating...
