DRETOP UR5-90JVT Programmable High-Temperature Vacuum Drying Oven

Overview

The DRETOP UR5-90JVT Programmable High-Temperature Vacuum Drying Oven is an engineered solution for thermal processing under controlled low-pressure environments. It operates on the principle of vacuum-assisted drying—reducing ambient pressure within the chamber to lower the boiling point of volatile components (e.g., solvents, moisture, or residual process gases), thereby enabling efficient dehydration, degassing, annealing, and curing at elevated temperatures without oxidative degradation. Designed for applications demanding both high thermal stability (up to 500 °C) and precise vacuum integrity (≤133 Pa), this oven supports inert-atmosphere processing via optional nitrogen purging and integrates programmable multi-stage control for repeatable thermal-vacuum cycles. Its dual-wall stainless steel construction, water-cooled door seal, and argon-welded chamber joints ensure long-term vacuum reliability and thermal consistency—critical for semiconductor packaging, battery electrode conditioning, aerospace composite curing, and advanced material synthesis.

Key Features

• Programmable multi-segment controller with T-type full-color touchscreen interface, supporting independent scheduling of temperature ramping, vacuum hold, inert gas injection, and cooling phases.
• Stainless steel (AISI 304) double-layer inner chamber with argon arc welding and silicone-free high-temperature door gasket (rated to 500 °C), reinforced by water-jacketed door cooling to suppress seal thermal aging.
• Forced-air convection heating system with axial fan and baffle-guided airflow, delivering ±1 °C temperature uniformity across the 90 L working volume (450 × 450 × 450 mm).
• Dual-sensor safety architecture: independent over-temperature cut-off sensor plus microprocessor-based PID controller with deviation alarm and configurable threshold alerts.
• Integrated vacuum monitoring via digital vacuum gauge (0–1000 Pa range), with real-time display and logging capability synchronized with temperature profiles.
• Energy-efficient insulation using high-density ceramic fiber between inner and outer walls, minimizing thermal loss and meeting IEC 61000-3-2 harmonic emission standards.

Sample Compatibility & Compliance

The UR5-90JVT accommodates powder samples, thin-film substrates, ceramic green bodies, lithium-ion battery cathodes/anodes, MEMS wafers, and polymer composites—all without particle dispersion due to the absence of forced air during vacuum operation. Its oxygen-free processing environment complies with ASTM E145 (Standard Specification for Gravity-Convection and Forced-Ventilation Ovens) and supports GLP/GMP workflows through audit-trail-capable parameter logging. Optional Q-type dual-stage condensate trap and J-type inline cold trap are available for high-moisture or solvent-laden samples, ensuring pump protection and extended maintenance intervals. The unit meets CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive) and conforms to ISO 14644-1 Class 8 cleanroom-compatible surface finish specifications.

Software & Data Management

The embedded T-type controller supports USB export of time-stamped CSV logs containing temperature setpoint, actual chamber temperature, vacuum pressure, and event timestamps (e.g., door open/close, alarm triggers). Optional Ethernet or RS485 Modbus RTU connectivity enables integration into centralized laboratory information management systems (LIMS) or SCADA platforms. All operational parameters—including up to 32 programmable steps per cycle—are password-protected and retain settings after power interruption. Firmware adheres to FDA 21 CFR Part 11 principles for electronic records: user authentication, immutable audit trails, and electronic signature readiness. Data encryption (AES-128) is applied during USB transfer to safeguard proprietary process recipes.

Applications

• Thermal debinding and sintering pre-treatment of metal injection molded (MIM) parts.
• Electrode drying and binder pyrolysis in lithium iron phosphate (LFP) and NMC battery R&D.
• Outgassing of optical components and vacuum chamber components prior to ultra-high vacuum (UHV) assembly.
• Moisture removal from hygroscopic pharmaceutical excipients under nitrogen blanket to prevent hydrolysis.
• Stress-relief annealing of additively manufactured titanium alloys (e.g., Ti-6Al-4V) without surface oxidation.
• Accelerated aging tests of encapsulants and conformal coatings per IPC-CC-830B and MIL-STD-883H Method 1008.

FAQ

What vacuum level can the UR5-90JVT achieve, and how is it maintained?
The chamber achieves and sustains ≤133 Pa (1 Torr) using a factory-integrated旋片式 (rotary vane) vacuum pump; sustained performance relies on the water-cooled door seal and argon-welded chamber integrity.
Is the oven suitable for oxygen-sensitive materials?
Yes—vacuum operation eliminates ambient oxygen, and optional nitrogen purge capability allows for inert-gas backfilling to <100 ppm O₂ residual.
Can multiple thermal-vacuum cycles be automated?
Yes—the T-type controller supports up to 32 programmable segments per cycle, including dwell times at target vacuum and temperature, with automatic transition logic.
How is temperature uniformity validated?
Uniformity is verified per ASTM E2207 using nine calibrated PT100 sensors placed across the load zone; certified test reports are provided with each unit.
What safety certifications does the UR5-90JVT hold?
It carries CE marking for EMC and LVD compliance, and its electrical design follows IEC 61010-1:2010 for laboratory equipment safety.
