Customized Temperature Range MVR Evaporator For Energy Efficient Evaporation Process

Engineer-to-order MVR (Mechanical Vapor Recompression) evaporator with a customizable operating temperature window to fit heat-sensitive products, viscous concentrates, and high-salinity streams. By recompressing secondary vapor as the heating medium and precisely controlling ΔT and boiling point, the system delivers energy-efficient evaporation, stable quality, and predictable OPEX across diverse processes.

• Customized temperature range: low-temperature vacuum duty for thermally sensitive liquids; higher ΔT options for robust feeds.
• Fine ΔT control: VFD-driven compressor turndown and smart PID keep film temperature uniform and protect product quality.
• Energy efficiency: latent heat recycled via vapor recompression; minimal fresh steam after start-up.
• Continuous automation: PLC/HMI recipes, historian, alarms, and optional remote diagnostics for 24/7 uptime.
• Material options: SS316L/duplex wetted parts; Ti/Hastelloy available for corrosive duties.

• Process Fit: Tailored boiling temperature to match product thermal limits and viscosity profiles.
• Quality Protection: Low film temperature and uniform heat flux reduce degradation, discoloration, and fouling.
• Lower OPEX: Recycled latent heat and optimized ΔT reduce utility consumption and total cost.
• High Availability: Redundancy on critical pumps, CIP-ready design, and predictive fouling monitoring.
• Sustainability: High-quality condensate recovery supports reuse and environmental compliance.

Secondary vapor is mechanically compressed to elevate saturation temperature, then reused as the primary heat source. Tight control of ΔT/LMTD and residence time maximizes heat-transfer efficiency, limits scaling, and preserves product attributes.

Closed-loop regulation of level, ΔT, pressure, and conductivity; interlocks for compressor/VFD, vacuum/NCG handling, and condensate quality guard. Optional AFE/harmonic filters for power-quality compliance.

Hygienic, drainable layouts with validated CIP; surface finishes suited to food/chemical duties. Anti-scale dosing available for high-salinity feeds and long campaigns.

• Feed conditioning: filtration/softening, pH trim, deaeration to minimize corrosion and scaling.
• MVR evaporation (vacuum): compressor turndown and ΔT setpoints define the operating temperature band.
• Condensate management: polishing (if needed) to meet reuse/discharge targets.
• Concentrate routing: to crystallizer/centrifuge/dryer or returned to upstream process per flowsheet.
• Automation: recipe-based temperature programs for different products or seasonal conditions.

• MVR evaporator/forced-circulation body with circulation pumps and vapor–liquid separator
• Mechanical vapor compressor (turbo/Roots) with VFD for temperature/ΔT control
• Main heater, preheaters, condensers, vacuum/NCG handling skid
• PLC/HMI/SCADA with historian; instrumentation (T/P/flow/cond/level)
• CIP skid; anti-scale dosing; optional condensate polishing filters/RO
