Heat pump evaporator with natural circulation and heat exchanger with scraped heating surfaces.
The R series evaporators have a heating system based on a heat pump and operate under vacuum at 5 kPa 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
