Product Overview
This industrial rotary evaporator series is engineered for 24/7 continuous large-scale solvent recovery, high-concentration purification, and pilot production. Supporting flask capacities from 20L to 100L+ (customizable up to 200L), the system creates a continuously renewed thin liquid film on the flask's inner wall under controlled vacuum conditions.
This mechanism maximizes heat transfer efficiency and dramatically reduces batch cycle times, enabling rapid distillation at lower temperatures to prevent thermal degradation of sensitive active compounds.
Key Technical Features
Engineered for 24/7 Continuous Operation: Powered by heavy-duty, high-torque induction motors and a reinforced stainless steel exoskeleton frame. This system withstands maximum liquid loads at continuous 130 RPM without structural fatigue-eliminating the frequent downtime common when scaling up from benchtop models.
Ultimate Vacuum Stability (< 399.9 Pa / 3 mmHg): Features a proprietary dual PTFE and Viton sealing system. By maintaining strict, long-cycle vacuum levels, it lowers solvent boiling points significantly, enabling rapid distillation while protecting heat-sensitive botanical extracts or APIs from thermal degradation.
Uncompromised Chemical Purity: All wetted, vapor-contacting components are strictly constructed from premium Borosilicate Glass 3.3 and virgin PTFE. This guarantees absolute chemical resistance against aggressive organic solvents, strong acids, and bases.
Fail-Safe Process Automation: Integrated with a motorized auto-lift mechanism that automatically raises the evaporation flask out of the heating bath during sudden power interruptions, preventing thermal runaway and protecting your valuable process batch.
Turnkey Explosion-Proof (Ex) Configurations: For processing volatile and flammable solvents (e.g., Ethanol, Hexane, Acetone), systems can be fully configured with spark-free induction motors, ATEX/UL-compliant isolated control cabinets, and armored cabling tailored to hazardous location standards.

Core Sectors & Applications
Pharmaceutical & API: Concentration, crystallization, and solvent removal of heat-sensitive active pharmaceutical ingredients under strict GMP-compliant environments.
Chemical Processing: Industrial organic solvent recycling, bulk intermediate separation, and purification of specialty chemicals.
Natural Extracts & Botanicals: Low-temperature extraction and concentration of essential oils, hemp/cannabis derivatives, botanical flavors, and bio-compounds without altering original profiles.
Manufacturing Quality Assurance (E-E-A-T Validation)
Every industrial unit undergoes a rigorous, documented factory testing protocol prior to shipment to ensure immediate field readiness and minimize on-site commissioning time:
24-Hour Dynamic Vacuum Hold Test: Continuous static and dynamic pressure checks under maximum rotation to verify zero-leakage seal integrity.
Thermal & Electrical Insulation Validation: Complete multi-point mapping of bath temperature uniformity and high-voltage insulation safety testing.
72-Hour Mechanical Stress Run: Multi-day load testing at maximum RPM and weight capacity to verify structural alignment, bearing longevity, and motor stability.
FAQ
Q: Can these systems be customized to meet strict regional safety regulations like ATEX or UL/NEC?
A: Absolutely. For hazardous industrial environments, we provide fully certified Explosion-Proof (Ex) setups. We customize the control systems, lift motors, and heating elements to comply with local codes, utilizing ATEX-certified components for Europe or UL/NEC compliant components for North America.
Q: How do you guarantee international shipping safety for fragile glass components?
A: We pack all equipment in heavy-duty, export-grade ISPM-15 compliant wooden crates integrated with custom-molded, high-density foam suspension padding. Furthermore, all shipments are fully insured. In the rare event of transit damage, replacement parts are dispatched via priority air express within 24-48 hours at zero cost to you.
Q: Do you provide OEM, private labeling, and custom engineering for global distributors?
A: Yes, we actively partner with global laboratory and industrial equipment distributors. Our engineering team can integrate custom PLC automation (e.g., Siemens/Allen-Bradley), modify setups with dual condensers for ultra-low boiling point solvents, provide custom frame coatings, and offer private labeling to match your brand identity.
Q: How do you handle after-sales service and wear-and-tear parts supply for international clients?
A: Every industrial evaporator comes with an complimentary extra set of critical wear parts (such as PTFE vacuum seals and O-rings). For ongoing support, we maintain an extensive inventory of spare glass and mechanical parts ready for global express dispatch, backed by lifetime remote technical support from our engineering team.
