20L Industrial Digital Rotary Evaporator

• Industrial wide-range forward & reverse intermittent rotation: 10–150rpm stepless adjustable, timed alternating stirring prevents sedimentation & agglomeration of powder and high-solid suspensions, ideal for bulk viscous sample concentration.
• Integrated water & oil dual heating mode from RT to 180℃: ±1℃ water bath for aqueous & low-boiling materials; ±3℃ oil bath for high-boiling grease and long-chain organic reagents, covering both low & high-temperature distillation workflows on one unit.
• High vacuum & high evaporation efficiency: Ultimate vacuum below 2.6hPa, max water evaporation rate 4.0L/h. Triple vertical coil condenser with large cooling area greatly boosts solvent recovery rate for mass production.
• Integrated multi-function LCD visual operation: Single screen synchronously displays temperature, speed, rotation direction and remaining runtime for intuitive parameter adjustment, easy operation for workshop staff.
• 180mm long-stroke one-click motorized lift: Smooth silent lifting simplifies installation & disassembly of 20L large flasks, quickly separating material from heating medium to avoid boil-dry damage.
• Complete industrial large-volume glassware kit: 20L evaporation flask + 10L receiving flask with bottom drain valve, eliminating shutdown for distillate pouring and shortening production downtime.
• Two-section vertical triple-coil condenser: 1.2㎡ huge heat exchange area delivers high condensation efficiency, suppressing escape of low-boiling solvents and reducing raw material loss.
• Double-layer PTFE vacuum seal + vacuum-preserved collection valve: Double corrosion-resistant layers prevent air leakage under long-term negative pressure; receiving vessels can be swapped without vacuum breaking for uninterrupted continuous distillation.
• Standardized 16mm universal hose connectors: Uniform outer diameter for cooling circulator and vacuum pump pipelines, easy assembly & disassembly matching existing workshop auxiliary equipment.
• Five-fold full-range interlock safety protection: Auto shutdown triggered by motor over-current, earth leakage, lifting overload, boil-dry and overheating, suitable for long-duration unattended mass production in workshops.

• Equipment assembly & pipeline connection: Install 20L evaporation flask, triple coil condenser and 10L drain-valve receiving flask; connect cooling circulator and diaphragm vacuum pump via 16mm standard connectors, inspect air tightness of double-layer PTFE sealing ring.
• Heat medium filling: Fill pure water for water bath mode, heat conduction silicone oil for oil bath mode; connect 220V power supply, LCD screen completes automatic full-unit self-check.
• Process parameter setup: Set rotation speed 10–150rpm, target water/oil bath temperature and 0–999min timer on screen; activate forward-reverse intermittent stirring for high-solid-content samples.
• Motorized lifting positioning: Tap one-key lift to fully submerge 20L evaporation flask into heating bath and lock position.
• High-vacuum mass distillation production: Start vacuum pump to build ultimate vacuum below 2.6hPa, PID maintains constant temperature automatically. Triple condenser continuously condenses and recycles solvent, raw material can be supplemented continuously via feeding port for batch production.
• Vacuum-preserved distillate collection: Drain residual distillate through bottom valve of receiving flask; activate switching valve for vessel replacement without vacuum breaking or distillation interruption.
• Post-production shutdown sequence: Release system vacuum first, motor-lift heating bath away from evaporation flask, stop rotation and heating; drain bath medium after unit & glassware fully cool down, clean residual materials on condenser and sealing fittings.
• Long-term shutdown storage: Cut off power supply, wipe outer unit surface and drain residual solvent; detach glassware for separate storage to slow aging of double-layer PTFE sealing ring.

• Shockproof packaging: Standard protective packaging equipped with integrated high-density shock-absorbing inner cushion materials separating main unit, full glassware kit, power cord and printed user manuals for collision damage prevention during long sea & land transit; reinforced protective structure will be applied by default for bulk export orders.
• Full package contents: LRE-20L-Pro industrial rotary evaporator main unit, complete 20L industrial glassware kit (evaporation flask / triple coil condenser / drain-valve receiving flask), 220V standard power cord, printed factory full user manual, factory ultimate vacuum & temperature accuracy quality inspection certificate.
• Note on reference package size & gross weight: Outer package dimensions and full-set gross weight are only industry estimated reference values, final specifications subject to actual factory outgoing packaging.
• Lead time rule: In-stock standard models ship within 3–10 working days; orders with matched high-power vacuum pumps and custom continuous feeding kits take 15–30 working days.
• Logistics options: Sea freight, air freight and LTL full-truck road transport available, dedicated logistics line for bulk overseas export of industrial mass-production chemical pretreatment equipment.
