Shanghai Yiheng BPG Series High-Temperature Forced-Air Drying Oven

Overview

The Shanghai Yiheng BPG Series High-Temperature Forced-Air Drying Oven is engineered for precise thermal processing in research laboratories, quality control environments, and industrial R&D settings where consistent, uniform heat distribution at elevated temperatures is critical. Designed around the principle of forced convection—where a variable-speed centrifugal fan circulates heated air across a mirror-finish stainless steel chamber—the BPG series ensures high thermal homogeneity and rapid temperature recovery after door opening. Its operational range spans from ambient +20°C up to 400°C (AH models) or 500°C (BH models), making it suitable for applications including moisture loss determination, pre-baking of substrates, thermal aging studies, sterilization validation support, and residual solvent removal. The oven’s structural integrity is reinforced by ceramic fiber door gaskets rated for continuous operation at maximum setpoints, eliminating thermal degradation over extended duty cycles.

Key Features

• Mirror-polished 304 stainless steel interior with seamless, radius-rounded corners—designed to minimize particulate retention and simplify cleaning under GLP-compliant maintenance protocols.
• Advanced PID-based fuzzy logic controller delivering ±0.5°C temperature stability and 0.1°C resolution; supports ramp-soak-hold profiles with minimal overshoot during setpoint transitions.
• Seven independent multi-segment programs (up to 9 steps per program, 63 total programmable steps), each configurable with time duration (0–5999 minutes), target temperature, and fan speed setting.
• Dual-stage safety architecture: primary control loop backed by an independent mechanical over-temperature limiter that interrupts power if chamber temperature exceeds user-defined threshold—fully compliant with IEC 61010-1 requirements for laboratory electrical equipment.
• Adjustable airflow system with stepless fan speed regulation enables optimization for both low-mass samples requiring gentle drying and high-thermal-mass loads demanding rapid equilibration.
• Optional RS485 serial interface (Modbus RTU protocol) allows integration into centralized lab management systems for remote monitoring, data logging, and audit-trail generation per FDA 21 CFR Part 11 requirements when paired with compliant software.

Sample Compatibility & Compliance

The BPG series accommodates a broad spectrum of sample formats—from Petri dishes and crucibles to metal trays and custom jigs—thanks to its modular shelf design and unobstructed chamber geometry. All standard configurations meet ISO 17025 calibration traceability prerequisites when used with external reference thermometers. The ovens are constructed in accordance with GB/T 5170.1–2016 (Chinese national standard equivalent to IEC 60068-3-5 for environmental testing equipment) and incorporate grounding continuity, insulation resistance, and dielectric strength safeguards aligned with EN 61010-1:2010. For pharmaceutical or medical device manufacturing, the BPG series supports IQ/OQ documentation packages and can be validated for use in processes governed by USP , ISO 14644-1 cleanroom auxiliary functions, or ASTM E2875-13 (Standard Guide for Thermal Validation of Dry Heat Sterilization Processes).

Software & Data Management

While the BPG series operates autonomously via its embedded touch-screen interface, optional connectivity modules enable interoperability with third-party data acquisition platforms. The RS485 port transmits real-time chamber temperature, programmed step status, and alarm events at user-configurable intervals. When interfaced with validated PC-based software (e.g., LabVIEW-compatible drivers or Yiheng’s OEM data logger suite), the system generates timestamped CSV or PDF reports featuring full thermal history, deviation alerts, and electronic signatures—satisfying ALCOA+ data integrity principles. Printer output (via optional thermal or dot-matrix units) provides hard-copy records suitable for batch release documentation in regulated environments.

Applications

• Moisture content analysis per AOAC 950.46 and ASTM D2298 for polymers, ceramics, and pharmaceutical excipients.
• Pre-conditioning of test specimens prior to tensile, impact, or adhesion testing (ASTM D618, ISO 291).
• Thermal stabilization of calibration standards and reference materials before gravimetric analysis.
• Accelerated aging studies for packaging materials, conformal coatings, and battery components under controlled dry-heat stress (IEC 60068-2-2, JIS C 0068).
• Residue ashing support for elemental analysis workflows (EPA Method 3010A, ASTM D5630).
• Pre-heating of glassware and metal tools in semiconductor fabrication cleanrooms where organic contamination must be minimized.

FAQ

What is the maximum allowable operating temperature for BH-series models?

The BH configuration is rated for continuous operation up to 500°C, with thermal insulation and gasketing certified for uninterrupted service at this upper limit.
Can the BPG oven be used for sterilization?

It is not classified as a sterilizer per ISO 17665 or EN 554; however, it supports dry-heat depyrogenation cycles (e.g., 250°C for 45 minutes) when validated per user-defined protocols.
Is NIST-traceable calibration available?

Yes—Yiheng offers factory calibration certificates with uncertainty budgets traceable to CNAS-accredited standards; on-site verification services are also available upon request.
How many shelves can be installed simultaneously?

Standard delivery includes two adjustable stainless steel shelves; additional load-bearing shelves (part number BPG-SH-SS) may be added up to the manufacturer-specified maximum load capacity for each model.
Does the oven comply with electromagnetic compatibility (EMC) directives?

All BPG series units are tested to IEC 61326-1:2013 for emission and immunity performance, meeting CE marking requirements for laboratory equipment within the European Economic Area.
