Product Description
3P Compression MVR Evaporator Bearing Core 480V Steam Roots Compressor
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.

Key Benefits
  • 3P/480V compatibility: Standard North American LV power; VFD-ready for turndown and soft start.
  • Robust bearing core: Heavy-duty rolling bearings, optimized lubrication, and shaft sealing for long MTBF.
  • Energy efficiency: Roots recompression minimizes fresh-steam demand after start-up.
  • Stable film duty: Tight ΔT/LMTD control under vacuum protects product quality and limits fouling.
  • Maintenance-friendly: Split housing options, cartridge seals, and online vibration/temperature monitoring.
Process & Thermal Economy
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.
Compressor & Bearing Core Highlights
  • 3P 480V LV motor with VFD for load following and anti-surge margin control
  • Hardened rotors, precise clearances, inlet silencing/filtration, and discharge pulsation control
  • Bearing core: high-capacity bearings, forced-oil lubrication, RTD/VT monitoring, quick-change cartridges
  • Shaft seals per duty (mechanical/dry gas seal) with leakage recovery to vacuum system
Process Overview -- MVR with Roots Compressor
Flow diagram: feed conditioning → evaporator → Roots MVR compression → condensate polishing → concentrate handling
  • Feed conditioning: filtration/softening, pH trim, antiscalant to mitigate Ca/Mg/Si scaling.
  • Evaporation (vacuum): falling-film or forced-circulation body with vapor-liquid separator.
  • MVR compression: Roots machine lifts vapor temperature; ΔT set by VFD speed control.
  • Condensate polishing: optional filters/RO/AC to meet reuse/discharge limits.
  • Concentrate routing: to crystallizer/centrifuge/dryer or ZLD solids discharge.
Key Components
  • Evaporator (falling film / forced circulation) with heat-recovery preheaters
  • 480V 3-phase Roots steam compressor + VFD, inlet filter/silencer, discharge cooler
  • Surface condenser, vacuum/NCG handling skid, vapor-liquid separator
  • PLC/HMI/SCADA; instruments (T/P/flow/cond/level/vibration/RTD)
  • CIP skid; antiscalant dosing; hygienic/drainable layouts in SS316L/duplex
Performance & Sizing
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.
FAQ
Why choose a Roots compressor over turbo?
Roots machines offer ruggedness, simple control, and strong low-ΔT lift at modest compression ratios--ideal for many MVR duties.
How do you protect the bearing core?
Inlet filtration, oil conditioning, continuous vibration/temperature monitoring, and planned maintenance windows extend bearing life.
Is 480V the only option?
No. Systems can be built for 380-480 V LV or 3.3-11 kV MV; we match local power, codes, and MCC standards.
