#### Hot water/steam evaporator with natural circulation and heat exchanger with scraped heating surfaces. [CONTATTA UN ESPERTO](https://www.veoliawatertechnologies.it/contattaci-web2lead) [Overview](#1) [Product range and Resources](#2) ## Overview 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:**  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® PC R-Series Con una capacità giornaliera variabile da 150 a 2.000 litri, lo scambio di calore avviene tramite una camicia conica posta alla base della camera di evaporazione. Contemporaneamente, la superficie di riscaldamento interna viene continuamente pulita dai raschiatori e il concentrato rimescolato, consentendo quindi di ottenere un'elevata concentrazione finale.
