The Forced Air Drying Oven BJPX-HG Series provides controlled temperature drying and heating applications in laboratory environments. This forced convection system operates from RT+10°C to 300°C with ±1°C temperature fluctuation and LCD display control. The unit features a 138L capacity chamber with 3 adjustable shelves and programmable timing from 1 minute to 9999 hours or continuous operation.
The forced convection design ensures uniform heat distribution throughout the chamber, with temperature uniformity maintained within ±2.5% of maximum temperature. The 0.1°C temperature resolution enables precise control for temperature-sensitive drying protocols. Digital LCD interface provides clear monitoring of operating parameters during extended drying cycles.
How It Works
The BJPX-HG Series operates on forced convection heating principles, where heated air is continuously circulated throughout the chamber by an internal fan system. This active air circulation eliminates temperature gradients and ensures uniform heat distribution across all shelf levels. The heating elements warm ambient air, which is then forced through the chamber in a controlled circulation pattern.
Temperature control is maintained through a feedback system that monitors chamber temperature via internal sensors and adjusts heating element output accordingly. The LCD controller processes temperature data and maintains set points within ±1°C fluctuation. The forced convection design accelerates heat transfer compared to natural convection systems, reducing drying times and improving temperature uniformity.
The programmable timer system allows for automated operation cycles, shutting down heating when the specified time period elapses. For continuous operation applications, the timer can be bypassed to maintain constant temperature conditions for extended periods.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Chamber Capacity | 138L volume with three adjustable shelves | Entry-level models often provide 50-80L capacity | Larger capacity allows processing more samples per batch, improving laboratory throughput. |
| Temperature Range | RT+10°C to 300°C operating range | Basic units typically limited to 250°C maximum | Extended high-temperature capability supports sterilization and high-temperature material processing. |
| Temperature Control | ±1°C fluctuation with 0.1°C resolution | Standard models often provide ±2-3°C control | Superior temperature stability ensures consistent results for temperature-sensitive protocols. |
| Circulation System | Forced convection with active air circulation | Natural convection systems rely on passive air movement | Active circulation eliminates hot spots and reduces drying time through improved heat transfer. |
| Timer Programming | 1-9999 minutes/hours or continuous operation | Basic models may have limited timing options | Extended timing range accommodates both short and long-duration protocols without interruption. |
The BJPX-HG Series offers substantial chamber capacity with precise temperature control and extended operating range. The forced convection design and programmable timing provide versatility for diverse laboratory drying applications requiring consistent thermal conditions.
Practical Tips
Verify temperature accuracy using certified reference thermometers at multiple set points across the operating range.
Why: Ensures measurement traceability and compliance with analytical method requirements.
Clean the chamber and shelves after each use to prevent cross-contamination between samples.
Why: Residue buildup can affect temperature uniformity and compromise subsequent drying operations.
Allow adequate spacing between samples to ensure proper air circulation around all items.
Why: Proper airflow prevents uneven drying and maintains temperature uniformity throughout the load.
Always wear heat-resistant gloves when handling items from the chamber at elevated temperatures.
Why: Heated samples and chamber surfaces can cause burns even after temperature setpoint is reduced.
Record chamber temperature throughout drying cycles for critical applications requiring documentation.
Why: Temperature logs provide evidence of proper processing conditions for quality assurance and method validation.
If temperature uniformity appears compromised, check that the circulation fan is operating properly.
Why: Fan malfunction eliminates the forced convection advantage and creates temperature gradients in the chamber.
Pre-heat the chamber to set temperature before loading samples for consistent processing conditions.
Why: Starting with a stabilized thermal environment ensures uniform heating from the beginning of the drying cycle.
