Industrial MVR evaporator configured with a 480V three-phase (3P) Roots steam compressor and reinforced bearing core for high reliability. The compressor mechanically recompresses secondary vapor to reuse latent heat as the primary duty, delivering low OPEX, stable ΔT control, and continuous 24/7 throughput for chemical, food, and wastewater/ZLD applications.
The Roots compressor raises vapor pressure/temperature and feeds it back to the heater. Optimized compression ratio, ΔT setpoint, and circulation velocity maintain high heat-transfer coefficients and low specific energy consumption, with predictable condensate quality for reuse.
| Parameter | Typical Range* |
|---|---|
| Operation | Continuous, vacuum duty |
| Electric use (MVR) | ~15–40 kWh per ton of water evaporated (duty/CR dependent) |
| Compression ratio | ~1.2–1.6 (application dependent) |
| Turndown | 50–100% via VFD speed control |
| Materials | SS316L / duplex; Ti/Hastelloy on request |
*Actual performance depends on feed chemistry, target concentration, compression ratio, and exchanger design.
Roots machines offer ruggedness, simple control, and strong low-ΔT lift at modest compression ratios—ideal for many MVR duties.
Inlet filtration, oil conditioning, continuous vibration/temperature monitoring, and planned maintenance windows extend bearing life.
No. Systems can be built for 380–480 V LV or 3.3–11 kV MV; we match local power, codes, and MCC standards.
