No air emissions ever! EVALED evaporator technologies operate as a closed loop system under vacuum. Atmospheric evaporators lose valuable energy through air emissions and may require an air permit or waiver for compliant operation. EVALED evaporators have an efficient design with one inlet and two discharge streams – concentrate and distillate.
PC- Heat Pump Vacuum Evaporators
PC heat pump evaporators offer flexibility, low electrical energy consumption, and superior reliability.
- Operating pressure of 7-9 kPa (1.0–1.3 PSIA)
- Lowest boiling temperatures: 30-40 °C (86-104 °F)
- Ozone friendly refrigeration gas (R 134)
F Series Evaporators
- Designed to treat low to medium wastewater flow rates and produce maximum distillate quality.
- Forced circulation and low boiling temperatures reduce rates of scaling, corrosion, and fouling.
- Capacities range from 700-24,000 L (185-6,340 gal) of distillate production per day.
R Series Evaporators
- Designed for low flow, highly contaminated or pre-concentrated waste streams.
- Scraped surfaces allow treatment of precipitating waste streams or crystallization of concentrate to achieve Zero Liquid Discharge (ZLD) goals.
