[ Product listing ](/en/technologies-1 " Product listing") #### Heat pump evaporator with natural circulation and heat exchanger with scraped heating surfaces. [CONTACT AN EXPERT](https://www.veoliawatertechnologies.com/en/contact) [Overview](#1) [Product range and Resources](#2) ## Overview ### EVALED PC EVAPORATORS - R SERIES The R series evaporators have a heating system based on a heat pump and operate under vacuum at 5kPa and around 30°C(86°F). Heat exchange occurs within a conical jacket, and the boiling chamber inside part is cleaned by internal scrapers that continuously stir concentrate. This configuration is designed to produce a concentrate with a high final concentration and a distillate with low conductivity. The R series production capacity varies from 150 to 2,000 liters per day and has several different systems for discharging concentrate. As for every EVALED® product, evaporation process is controlled by a PLC that controls wastewater to be treated automatic feed and distillate and concentrate discharge, requiring only minimum supervision by the operator. The R series is available in a variety of different alloys, depending on the feed nature. This is particularly important when treating aggressive waste. **The R series evaporators are particularly suitable when:** - wastewater has a high initial content of dissolved or suspended substances - wastewater has already been pre-concentrated - daily volumes are relatively small - distillate has to be of the highest quality - \*concentrate has to be recycled. **The R series is often supplied to the following markets:** - painting - coating - inks **The R series is the best solution for:** - Landfills and waste disposal - Graphic arts - Chemical industry - Galvanic industry ## 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.
