Engineer-to-order MVR (Mechanical Vapor Recompression) evaporator with forced circulation, designed for continuous seawater/brine desalination and SWRO brine concentration. Tuned for 440 V low-voltage grids (50/60 Hz configurable), it recycles latent heat via mechanical recompression to achieve high energy efficiency, stable throughput, and reduced discharge volumes.

• Higher water recovery: Concentrates SWRO brine to boost overall desalination recovery and cut blowdown.
• Energy savings: Electric-duty MVR minimizes fresh steam after start-up, lowering OPEX and CO₂ footprint.
• Scaling mitigation: Forced circulation maintains high shear and stable ΔT/LMTD to limit CaSO₄/CaCO₃ scaling.
• Corrosion resilience: SS316L/duplex/Ti options for chloride-rich feeds; drainable hygienic layouts.
• Continuous automation: PLC/HMI recipes, alarms, historian, remote support for 24/7 uptime.

Secondary vapor is mechanically compressed to raise saturation temperature and reused as the heating medium. High-velocity forced circulation stabilizes heat transfer on saline feeds. Tight control of pressure, ΔT, and residence time enables gentle, efficient evaporation with consistent condensate quality.

LV integration for 440 V (50/60 Hz), with VFD-driven compressor/pumps, soft-start, and optional AFE/harmonic filters for grid compliance. MV step-up options available on request.

Wetted parts in SS316L/duplex or titanium for chloride service; anti-scale dosing, validated CIP, sloped piping, and large clean-outs support long campaigns and fast turnarounds.

• Pretreatment: screening/filtration, antiscalant/pH trim to protect exchangers and compressor.
• MVR evaporation (vacuum): compressor discharge pressure sets ΔT; shell vacuum defines boiling point.
• Condensate polishing: optional filters/RO/UV to meet reuse or potable/industrial water specs.
• Concentrate routing: to crystallizer or regulated discharge; integrates with ZLD where required.
• Automation: recipes for seasonal salinity/temperature shifts; alarm interlocks and remote diagnostics.

• MVR evaporator (forced-circulation) with circulation pump and vapor–liquid separator
• Mechanical vapor compressor (turbo/Roots) with VFD for ΔT/throughput control
• Main heater, preheaters, condenser, vacuum/NCG handling skid
• PLC/HMI/SCADA; instruments (T/P/flow/cond/level); historian & remote access
• CIP skid; anti-scale dosing; optional condensate polishing filters/RO/UV

*Performance depends on feed salinity/temperature, fouling tendency, compression ratio, and heat-transfer design.
