Description

ATOMFAIR® DVO-724 DOUBLE CHAMBER VACUUM DRYING OVEN

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® DVO-724 Vacuum Drying Oven represents an advanced engineering triumph in parallel material processing, offering supreme execution for multi-phase thermal processing. Constructed specifically as a robust double chamber calibrator, this automated workbench infrastructure is fully optimized for non-volatile material desiccation, technical tempering, and moisture-free testing profiles. The dual-zone configuration integrates standalone PLC electronics alongside custom solenoid valves to manage continuous vacuum pumping, inert gas filling, and exhaust phases independently. Built with a high-performance framework that guarantees independent heating box stability, this heavy-duty system avoids inter-chamber thermal crosstalk, ensuring excellent repeatability for world-class industrial laboratories.

Key Features & Advantages
  • Dual Independent Process Zones: Features two fully separate internal chambers supporting completely independent operational timelines, allowing discrete heating steps to run concurrently.
  • PLC Automated Sequence Loop: Outfitted with an automated control loop managing high-vacuum drawdown, nitrogen gas backfilling, and safety vents via precise electronic pressure switches.
  • Modular Heating Box Architecture: Special independent heating boxes with integrated fans allow rapid tube swaps without breaking internal temperature uniformity metrics.
  • Leak-Proof Air Duct Configuration: The advanced sealed internal air duct design stops hot air migration completely, yielding stable nitrogen atmospheres for continuous baking profiles.

APPLICATION SCOPE: Optimized precisely for drying non-volatile composite resins, vacuum baking inert technical specimens, processing non-flammable mineral samples, and executing high-volume structural heat treatments.
PACKAGING: Securely secured within a heavy-duty industrial export-grade wooden crate measuring 1450 × 850 × 1350 mm, braced with thick vibration-isolation framework to protect the dual mechanical vacuum meters.
IMPORTANT NOTICE: Do not introduce volatile or explosive organic compounds under any circumstances. Ensure the DN40 vacuum port and gas lines are thoroughly inspected for structural fitting wear before activating deep programmatic cycles.

This double-chamber vacuum drying oven must be operated within specified temperature and vacuum limits to prevent equipment damage and ensure safety. The unit is designed for processing non-volatile, non-flammable, and non-explosive materials only, with independent chamber control.

  • Operating Temperature Limits: Operate the oven only within the ambient+15°C to 150°C range to avoid overheating and component degradation.
  • Material Compatibility: Only load non-volatile, non-flammable, and non-explosive materials into the chambers to prevent fire or explosion hazards.
  • Vacuum Integrity: Ensure vacuum seals are intact and leakage does not exceed 5% over 24 hours to maintain process consistency and safety.
  • Electrical Safety: Connect the oven to a properly grounded power supply that meets the rated specifications to avoid electrical shock or fire.
  • Environmental Conditions: Place the oven in a dry, clean, and well-ventilated area away from flammable materials to minimize external risks.

Follow these steps to safely initialize and operate the double-chamber vacuum drying oven for a typical drying process. Ensure all required utilities (vacuum pump, nitrogen supply, power) are connected and operational before starting.

Required Equipment: External vacuum pump, Nitrogen gas source with pressure regulator, Appropriate power supply with grounding

  1. Inspect chambers
    Inspect each chamber for debris, damaged seals, or foreign objects before loading materials.
  2. Load materials
    Place the samples into the chambers ensuring they are non-volatile, non-flammable, and non-explosive and do not block the vacuum port.
  3. Close and seal doors
    Close the chamber doors and verify that the door gaskets form a proper seal to achieve vacuum.
  4. Set process parameters
    On the PLC controller, set desired temperature, vacuum level, and time for each chamber independently.
  5. Initiate vacuum and nitrogen purge
    Start the vacuum pump and open the vacuum valve to evacuate the chamber, then perform a nitrogen purge if required by process specifications.
  6. Monitor process conditions
    Monitor the vacuum gauges and temperature displays to ensure parameters remain within specified ranges during the cycle.
  7. Terminate and vent cycle
    Upon completion, close the vacuum valve, release vacuum by opening the air release valve, and allow chamber to cool before opening the door.

How does operating both chambers simultaneously affect temperature uniformity and vacuum integrity compared to single-chamber use?

The DVO-724's two chambers are fully independent with separate heating systems, temperature controllers, and valve-controlled vacuum lines. Simultaneous operation does not compromise performance: each chamber maintains its specified temperature uniformity of ±3°C (empty load) and vacuum degree ≤ -0.095 MPa independently. The sealed air duct design and solenoid valves ensure no cross-chamber interference.

Can the DVO-724 be used for drying flammable solvents if nitrogen purging is employed?

No. The DVO-724 is explicitly designed only for non-volatile, non-flammable, and non-explosive materials. Although the PLC-controlled nitrogen filling can create an inert atmosphere, the standard unit lacks explosion-proof electrical components, sealed heating elements, and safety venting required for flammable solvent processing. Any such use would require significant customization and compliance with local regulations.

What utility connections and floor loading are required for installing the DVO-724 vacuum drying oven?

The oven weighs approximately 1000 kg with external dimensions of 1450(H)×850(W)×1350(D) mm, necessitating a reinforced floor and adequate clearance for the 100 mm insulation thickness. It requires a vacuum pump connected to the DN40 port, a nitrogen supply to the Φ12 port, and a compressed air line to the Φ8 port for pneumatic valves. The cabinet surface temperature may reach ambient+15°C at 90°C working temperature, so proper ventilation is advised.

This double-chamber vacuum drying oven offers independent zone control and PLC-driven automation for vacuum, nitrogen fill, and vent processes, but its material compatibility is restricted to non-volatile, non-flammable, and non-explosive substances, and operation under inert atmosphere requires an external nitrogen supply.

Positive

  • PLC-automated process control: Fully automatic vacuum pumping, nitrogen filling, and air release through PLC and solenoid valves reduce operator intervention and improve reproducibility for production-scale drying cycles.
  • Independent dual-chamber operation: Each 500×500×500 mm chamber has separate heating and temperature control, allowing simultaneous processing at different temperatures or times, increasing throughput in batch workflows.

Trade-offs

  • Restricted material compatibility: The oven is explicitly designed only for non-volatile, non-flammable, and non-explosive materials, excluding many solvents and reactive compounds commonly dried under vacuum.
  • External nitrogen infrastructure required: Inert atmosphere operation via nitrogen filling depends on an external nitrogen supply and connection (Φ12 port), increasing facility setup complexity and consumable costs.
