DRETOP UR5-50JV High-Temperature Vacuum Drying Oven

Overview

The DRETOP UR5-50JV High-Temperature Vacuum Drying Oven is a precision-engineered thermal processing system designed for controlled dehydration, thermal stabilization, degassing, and inert-atmosphere annealing under deep vacuum conditions. It operates on the principle of lowering the vapor pressure of volatile components—primarily water and solvents—by reducing ambient pressure inside the chamber, thereby enabling effective drying at significantly lower temperatures than atmospheric ovens. This mechanism preserves thermally sensitive materials while accelerating moisture removal, preventing oxidation, and eliminating residual volatiles in applications ranging from semiconductor wafer baking to cathode active material conditioning for lithium-ion batteries. The unit is engineered for reproducible high-temperature operation up to 500°C within a sealed stainless-steel chamber, maintaining vacuum integrity via dual-stage sealing architecture and water-cooled door gaskets.

Key Features

• Stainless steel (SS304) double-walled inner chamber with argon arc welding joints ensures structural rigidity and long-term vacuum integrity.
• Forced-air circulation heating system delivers uniform thermal distribution (±1°C uniformity) across the 50 L working volume, critical for batch consistency in R&D and pilot-scale production.
• Water-jacketed door assembly with high-temperature silicone gasket and dual rotary latching mechanism maintains stable vacuum levels ≤133 Pa and minimizes thermal degradation of sealing surfaces.
• Microprocessor-based PID temperature controller with 0.1°C resolution, programmable ramp-soak profiles, over-temperature deviation alarm, and auto-recovery memory function after power interruption.
• Integrated recirculating water cooling unit condenses vapors prior to vacuum pump intake, protecting pump oil life and enhancing system reliability during high-moisture-load operations.
• Tempered double-glazed observation window enables real-time visual monitoring without compromising vacuum or thermal stability.
• Multi-layer insulation using high-density glass fiber between chamber and outer casing reduces surface temperature and energy consumption, complying with ISO 14001 energy-efficiency benchmarks.

Sample Compatibility & Compliance

The UR5-50JV accommodates powders, thin-film substrates, ceramic green bodies, battery electrode sheets, aerospace composites, and PCB assemblies—all without particle displacement due to absence of convective airflow. Its oxygen-free environment mitigates oxidation risks during high-temperature treatments, making it suitable for ASTM F2628-compliant semiconductor packaging bake-out, USP polymer stability studies, and IEC 62133-2 cell formation protocols. The system supports GLP/GMP documentation workflows through optional audit-trail-enabled controllers (T-type touch interface), and its construction meets CE machinery directive (2006/42/EC) and RoHS 2 compliance requirements.

Software & Data Management

The optional T-type color touchscreen controller provides intuitive graphical programming of multi-step vacuum-heat-cool cycles, including independent setpoints for chamber temperature, vacuum hold duration, and nitrogen backfill timing. All process parameters—including actual temperature/vacuum curves, event logs, and alarm timestamps—are exportable in CSV format for traceability. When configured with FDA 21 CFR Part 11-compliant firmware, the system supports electronic signatures, user-level access control, and immutable data archiving—enabling full regulatory alignment for pharmaceutical and medical device manufacturing environments.

Applications

• Thermal aging and outgassing of optical coatings and MEMS devices
• Pre-sintering of solid-state electrolyte pellets under inert gas purging
• Moisture removal from LiCoO₂, NMC, and silicon anode slurries prior to calendaring
• Post-deposition annealing of perovskite photovoltaic layers
• Residual solvent extraction from pharmaceutical granules and lyophilized intermediates
• Vacuum-assisted curing of epoxy encapsulants in avionics modules
• Controlled pyrolysis of biomass-derived carbon precursors

FAQ

What vacuum level can the UR5-50JV achieve and maintain during operation?

The system achieves and holds ≤133 Pa (1 Torr) using the integrated rotary vane vacuum pump; optional two-stage pumps or dry scroll alternatives can extend performance to ≤10 Pa for ultra-low moisture applications.
Is the chamber suitable for inert gas purging (e.g., N₂ or Ar)?

Yes—the unit includes dedicated gas inlet/outlet ports compatible with standard Swagelok fittings, supporting programmable inert gas backfill sequences and partial-pressure control.
Can multiple temperature zones be independently controlled?

No—the UR5-50JV features single-zone heating; however, its forced-air circulation design ensures spatial uniformity within ±1°C across the entire 415 × 370 × 345 mm cavity.
Does the system comply with electrical safety standards for international deployment?

It conforms to IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity), with CE marking valid for EU markets; UL/cUL listing is available upon request for North American installations.
How is calibration traceability supported?

The controller accepts external PT100 sensor inputs for third-party validation; DRETOP provides factory calibration certificates traceable to NIM (National Institute of Metrology, China) standards, with optional UKAS-accredited calibration services.
