[ Product listing ](/en/technologies-1 " Product listing") #### Hot water/steam evaporator with natural circulation and heat exchanger with scraped heating surfaces. [CONTACT AN EXPERT](https://www.veoliawatertechnologies.com/en/contact) [Vue d'ensemble](#1) [Product range and Resources](#2) ## Vue d'ensemble The AC R series evaporators have a heating system based on hot water or steam and operate under vacuum at 5 kPa and around 40°C (104°F). The client usually supplies the necessary power and mains water for heating the feed and cooling the distillate. The output streams are: a distillate that can be recycled as water and a solid or semi-solid concentrate with a TDS content > 90%. The AC R series evaporators are designed to work both continuously and per batch, by using a pump to discharge concentrate or by stopping the process and emptying boiling chamber. The AC R series production capacity varies from 3,000 to 12,000 liters per day. By using an optional intermediate heat exchanger, the AC R series can operate using steam as the heat source. As in every EVALED® product, evaporation process is controlled by a PLC, that controls the automatic feeding of wastewater to be treated and distillate and concentrate discharge, requiring only minimum supervision by the operator. **The AC R series is particularly suitable when:** - it is necessary to minimize the concentrate (to send to disposal) - wastewater has a very high initial content of dissolved or suspended substances - wastewater has already been pre-concentrated - daily volumes are relatively small - it is necessary to recycle high quality concentrate. **The AC R series evaporators are particularly suitable for:** ![](/sites/g/files/dvc4591/files/styles/default/public/image/2019/01/Evaled-ACR-Concentrate.jpg.webp?itok=lGMFOVxn) Concentrate from EVALED® AC R-series evaporator - Landfills & waste disposal - Glavanic industry - Food & Beverage industry - Mechanical, steel & automotive industry - Chemical industry - Printing - Energy ## Product range and Resources Product range [ ![Evaled evaporator RV F 60 surface treatment](/sites/g/files/dvc4591/files/styles/vwt_product_content_push/public/image/2025/04/Evaled-RV-push.jpg.webp?itok=SitNWiWX) ### Evaled™ RV series Evaled™ RV series: advanced technology in industrial wastewater treatment, offering two innovative ranges: the RV N and RV F series, processing up to 120 cubic meters of distillate daily.

It can produce between 20,000 and 60,000 liters of distillate per day. Effluent and industrial wastewater is heated by a hot water circuit which it transfers in a heat exchanger. A cold water circuit ensures rapid condensation of liquid discharges.

Simultaneously the inner heating surface is continuously cleaned by scrapers while also stirring the concentrate. This is designed to produce a high final concentration.
