The Constant-Temperature Drying Oven (BOV-TC) is a natural convection laboratory drying oven designed for precise thermal processing applications requiring stable temperature control. The unit operates across a temperature range of 50-200°C with ±1°C fluctuation control and temperature uniformity within ±3.5% of maximum temperature, providing consistent thermal conditions for sample preparation and materials processing.
Featuring a 42L internal chamber (350×350×350mm) with natural convection heating, the oven includes programmable timing control up to 9999 minutes and dual shelf configuration for efficient sample organization. The 850W heating system operates on standard AC220V power supply with optional 110V compatibility via external transformer, making it suitable for diverse laboratory environments requiring controlled thermal processing workflows.
How It Works
The drying oven operates on natural convection principles, where heated air circulates throughout the chamber without forced airflow. Thermal energy is distributed through the 850W heating element system, creating uniform temperature gradients that facilitate moisture removal and thermal processing. The natural convection design eliminates sample disturbance while maintaining consistent thermal conditions across the chamber volume.
Temperature control is maintained through integrated sensors and control algorithms that regulate heating element operation to achieve the programmed setpoint within ±1°C fluctuation. The timing system provides automated processing cycles up to 9999 minutes, allowing for extended thermal treatments while maintaining temperature stability. The dual shelf configuration maximizes sample capacity while ensuring uniform heat distribution throughout the 42L internal volume.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Temperature Control Precision | ±1°C fluctuation control with ≤±3.5% uniformity | Entry-level models often provide ±2-5°C control with limited uniformity specifications | Tighter temperature control ensures more reproducible results in moisture analysis and thermal conditioning applications. |
| Chamber Capacity | 42L internal volume (350×350×350mm) | Compact units typically offer 20-30L capacity with smaller dimensions | Larger capacity enables batch processing of multiple samples or accommodation of larger items in single thermal cycles. |
| Timing Range | 0-9999 minute automated control | Basic models often limit timer functions to 24-48 hours maximum | Extended timing capability supports applications requiring days-long thermal conditioning without manual intervention. |
| Heating Method | Natural convection with 850W heating system | Some models use forced convection which may disturb lightweight samples | Natural convection prevents sample disturbance while maintaining uniform heat distribution for delicate materials. |
| Power Flexibility | Dual voltage capability (220V standard, 110V optional) | Most units are fixed voltage requiring specific electrical configurations | Voltage flexibility simplifies installation in laboratories with different electrical standards. |
| Temperature Range | 50-200°C operating range | Basic models may start from room temperature with lower maximum temperatures | Elevated minimum temperature (50°C) reduces heating time while 200°C maximum covers most standard thermal processing applications. |
The BOV-TC offers precise temperature control (±1°C) with extended timing capability (9999 minutes) in a 42L natural convection design. The dual voltage compatibility and temperature uniformity specifications provide operational flexibility for demanding thermal processing applications.
Practical Tips
Verify temperature accuracy using an independent calibrated thermometer placed at multiple positions within the chamber before critical applications.
Why: Chamber temperature may vary slightly from display readings, particularly after extended use or at temperature extremes.
Clean the chamber and shelves with mild detergent after each use and inspect door seals monthly for proper closure.
Why: Residue buildup can affect heat distribution and compromised seals reduce temperature stability and energy efficiency.
Allow 10-15 minutes for temperature equilibration after reaching setpoint before loading time-sensitive samples.
Why: Natural convection systems require additional stabilization time compared to forced air units to achieve uniform temperature distribution.
Position samples with adequate spacing between containers and avoid blocking air circulation paths near chamber walls.
Why: Proper air circulation is essential for temperature uniformity in natural convection systems.
Document ambient laboratory temperature and humidity conditions when performing moisture determinations or standardized thermal treatments.
Why: Environmental conditions can affect heating rates and final moisture equilibrium in hygroscopic materials.
If temperature overshoot occurs during initial heating, reduce setpoint by 5-10°C and approach target temperature gradually.
Why: Natural convection systems may exhibit thermal lag, causing temporary temperature overshoot that can affect heat-sensitive samples.
Use heat-resistant gloves and allow chamber to cool before removing samples, especially after extended high-temperature cycles.
Why: Chamber walls and shelves retain significant thermal energy and can cause burns even after heating cycles complete.
Schedule annual temperature calibration verification using certified reference standards traceable to national standards.
Why: Temperature accuracy can drift over time due to sensor aging and thermal cycling, affecting reproducibility of thermal treatments.

Compliance
What is the temperature uniformity across the chamber volume?
Temperature uniformity is specified as ≤Max temp.±3.5%, ensuring consistent thermal conditions throughout the 42L chamber volume for reliable sample processing.
Can the oven accommodate glassware and metal containers?
Yes, the natural convection design and 50-200°C operating range are compatible with standard laboratory glassware and metal containers commonly used for thermal processing.
What are the internal chamber dimensions for sample planning?
The internal chamber measures 350×350×350mm (W×D×H), providing 42L capacity with dual shelf positions for organizing multiple samples or larger items.
How long can automated drying cycles run?
The timing system supports cycles from 0 to 9999 minutes (approximately 166 hours), enabling extended unattended thermal processing for applications requiring long conditioning times.
What power requirements are needed for installation?
Standard operation requires AC220V 50/60Hz power supply with 850W consumption. Optional 110V operation is available using an external transformer.
How does natural convection compare to forced air circulation?
Natural convection provides gentler heating without air disturbance, making it suitable for powders and lightweight materials that might be displaced by forced airflow, though heating may be slower.
What maintenance is required for consistent performance?
Regular cleaning of the chamber and shelves, periodic temperature calibration verification, and inspection of heating elements and seals are recommended for optimal performance.
Can the temperature control accommodate different heating rates?
The 850W heating system provides controlled temperature ramping, though specific heating rate control parameters should be verified in the detailed operating manual for your application requirements.
