Thermal Evaporators
Dramatically Reduce Wastewater Hauling Costs





Evaporation is a time-tested & cost-effective method for reducing the volume of water-based waste
Hauling is Costly
Industrial and commercial facilities that generate wastewater spend too much money paying for hauling & disposal of waste streams that are mostly comprised of water.
Evaporation is Cost Effective
ENCON Thermal Evaporators are utilized by 2,000+ facilities worldwide to evaporate the water portion of water-based wastes, reducing hauling/disposal volumes and cost by up to or even exceeding 99%.

Advantages of ENCON Thermal Evaporators
- Can handle different waste streams simultaneously
- Can handle very challenging and complex waste streams
- Dramatically reduces disposal volume & cost
- Eliminates sewer discharge accountability
- Achieve ZLD
- Safe to operate 24/7 ✔ Low operating costs
- Requires less operator intervention than most wastewater treatment technologies
- Very effective for process stream concentration

Mist Eliminator System

Superior Fabrication
ENCON Thermal Evaporators feature a polished 304 stainless steel exterior for superior corrosion resistance. Fully insulated on all sides (450°F, R-4.3). Standard 316L stainless steel tank and heat exchanger, with higher alloys available for corrosive applications.

Robust Heat Exchanger
ENCON fuel-heated Thermal Evaporators feature a highly efficient heat exchanger design, reducing fuel costs. Elevated in the tank, it allows solids to settle below for easy cleanout.

Forced Draft Burner
ENCON fuel-heated Thermal Evaporators use a forced draft burner for efficient, consistent heating with less flame impingement, quieter operation, longer blower life, and minimal impact from atmospheric conditions.

Level Sensing
Durable tuning fork level probes provide reliable level detection to facilitate evaporator auto-fill and fail safe shut down for low and high liquid level conditions.

- 7” touch screen HMI panel
- Continuous monitoring of flue gas, chimney, and liquid temperatures
- Continuous level probe diagnostics
- Alarm management and multi-year data logging
- NEMA 4 rated
- Scheduled preventative maintenance alarms
- Control system integration through Modbus TCP/IP
- Remote access through browser or mobile app
- Reliable safety monitoring and shutdown via certified safety relay


The optional ENCON-link service allows you to monitor the evaporator remotely, minimizing operator walk-by’s. Proactive alarm notification allows you to quickly address alarms and minimize downtime. Take advantage of maintenance alerts to help prevent component failures. Monthly performance reports and data driven diagnostics highlight opportunities for process improvement.

Process Description

Wastewater is automatically pumped or gravity fed into the evaporator through a 1" NPT fitting on the lid.
Once the evaporator is filled to the operating level, the heat source energizes, and water begins to boil.
As water is boiled off, the liquid level in the evaporator tank drops and is automatically replenished with water from the feed tank.
The evaporator continues in this cycle of boiling down a few inches and replenishing with feed water until the end-point concentration is reached.
The end-point concentration is automatically detected via a high fluid temperature or cycle timer setpoint, whichever is reached first.
Upon reaching the end-point concentration, the super-concentrated residue is pumped out of the evaporator to a disposal drum or tank.
