Boxun BXH-130S Precision Programmable Drying Oven

Overview

The Boxun BXH-130S Precision Programmable Drying Oven is an engineered solution for laboratories requiring stable, repeatable, and traceable thermal processing across research, quality control, and regulated manufacturing environments. Based on forced-air convection thermodynamics, the oven maintains precise temperature profiles through a high-efficiency axial fan system and rear-mounted heating elements—enabling rapid heat transfer and minimizing thermal stratification. Its chamber design incorporates strategically placed perforated air inlets and rear-to-front airflow routing to achieve ≤±1.9°C uniformity at 150°C—a performance benchmark aligned with ISO 14644-1 Class 100 cleanroom-compatible operation when equipped with the optional HEPA filtration module. The unit operates within a validated range of RT+5°C to 300°C, supporting applications from moisture loss determination and polymer curing to stability testing and residual solvent removal.

Key Features

• 5-inch high-resolution capacitive touchscreen interface with real-time display of setpoint/actual temperature, elapsed time, fan speed stage, damper position, and operational status
• Programmable thermal profiling: up to 30 segments per cycle, 99 cycles total, with ramp rate control (°C/min) and soak dwell functionality
• Dual-layer overtemperature protection: primary PID-based digital control loop + secondary independent mechanical thermal cutoff switch
• Adjustable forced-air circulation: 5-step fan speed control and 10-position exhaust damper for fine-tuned air exchange rate (ACH) management
• Post-cycle rapid cooling mode activated automatically upon timer completion, reducing chamber cooldown time without compromising structural integrity
• Comprehensive data logging: stores up to 4 million timestamped temperature records internally; exportable via USB to CSV or Excel-compatible formats
• Security and compliance features: screen lock with password protection, audit-ready event logging (alarms, door openings, program starts/stops), and scheduled operation via built-in calendar-based timer

Sample Compatibility & Compliance

The BXH-130S accommodates standard laboratory glassware, metal trays, ceramic crucibles, and polymer substrates within its 570 × 400 × 570 mm stainless steel (AISI 304) chamber. Optional accessories—including additional stainless steel shelves (up to 7 total), HEPA-filtered air intake modules (achieving ISO Class 5 / Federal Standard 209E Class 100 cleanliness), and calibrated wireless temperature probes (validated to 130°C)—extend its suitability for GxP-regulated workflows. The oven supports calibration and qualification protocols per ASTM E2251, ISO/IEC 17025, and USP , with optional NIST-traceable calibration certificates available for three-point verification (0°C, 60°C, 121°C). When integrated with FDA-compliant monitoring software, it meets 21 CFR Part 11 requirements for electronic records and signatures, including user authentication, audit trails, and immutable data archiving.

Software & Data Management

Internal firmware enables full-cycle data capture—including temperature curves, alarm timestamps, and parameter changes—with automatic timestamping and internal clock synchronization. Data exports via USB support direct import into LIMS or statistical process control platforms. Optional FDA/GMP Edition monitoring software provides remote access via Ethernet or Wi-Fi, configurable alarm notifications (email/SMS via GPRS module), role-based user permissions, and automated report generation compliant with ALCOA+ principles. The system logs all operator actions, parameter modifications, and system events with unique user IDs and time stamps—ensuring full traceability during regulatory inspections. Integration with third-party SCADA systems is supported through Modbus RTU over RS-485.

Applications

• Moisture content analysis (ASTM D2298, ISO 712)
• Thermal aging studies of polymers and composites
• Drying of pharmaceutical granules and excipients prior to compression
• Pre-conditioning of test specimens per ASTM D618 and ISO 291
• Residual solvent evaporation in coating and ink formulation labs
• Stability testing under ICH Q1 guidelines (long-term, accelerated conditions)
• Pre-heating of components for solder reflow simulation

FAQ

What is the maximum operating temperature and certified uniformity specification?
The BXH-130S is rated for continuous operation up to 300°C. At 150°C, temperature uniformity is specified as ±1.9°C across the working volume per internal validation protocol.
Does the oven support IQ/OQ/PQ documentation packages?
Yes—factory-issued qualification templates, installation checklists, and operational test protocols are provided. Optional third-party IQ/OQ services and 21 CFR Part 11–compliant PQ execution are available upon request.
Can the unit be integrated into a central laboratory monitoring network?
Yes—dual RS-485 interfaces support daisy-chained Modbus RTU communication; optional Ethernet/Wi-Fi gateway modules enable seamless integration with enterprise-wide environmental monitoring systems.
Is the internal data logger compliant with GLP audit requirements?
All logged data include ISO 8601 timestamps, user identifiers, and event descriptors. When used with FDA/GMP software, the system enforces electronic signature workflows, change controls, and immutable archival—fully satisfying GLP Annex 11 and FDA guidance on electronic records.
What maintenance intervals are recommended for optimal performance?
Fan filter inspection every 3 months; chamber seal integrity check semiannually; annual recalibration of primary temperature sensor against NIST-traceable reference standard; HEPA filter replacement every 12–18 months depending on usage intensity and ambient particulate load.
