Boante BAT-Series Industrial Forced-Air Constant-Temperature Drying Oven

Overview

The Boante BAT-Series Industrial Forced-Air Constant-Temperature Drying Oven is a precision-engineered thermal processing instrument designed for consistent, repeatable drying, curing, baking, and sterilization applications in industrial laboratories, quality control environments, and production support facilities. Utilizing convection-based heat transfer via a rear-mounted horizontal airflow system, the oven ensures uniform thermal distribution across the entire working chamber—critical for moisture removal from polymers, pharmaceutical excipients, ceramic precursors, metal coatings, and analytical reference standards. The chamber’s mirror-finish AISI 304 stainless-steel interior, combined with rounded internal corners and seamless welded construction, meets hygienic design requirements for cleanroom-adjacent use and facilitates rapid decontamination between cycles. Its operational temperature range—from ambient +10 °C up to 250 °C—supports both low-temperature desiccation and high-temperature post-curing protocols, while the ±1 °C temperature fluctuation and ±3% uniformity (at setpoint) reflect compliance with ISO 17025 calibration traceability expectations for routine thermal validation.

Key Features

• Microprocessor-based PID temperature controller with blue-backlit LCD interface, supporting both time-programmed and constant-setpoint operation modes
• PT100 platinum resistance thermometer with fast thermal response (<5 s to 90% step change) and minimal self-heating error (<0.05 °C at 250 °C)
• Forced horizontal airflow architecture using a thermally shielded centrifugal blower, minimizing temperature recovery lag after door opening (typical recovery <8 min to ±1 °C at 150 °C)
• Double-layer tempered glass observation window with argon-filled interlayer for thermal insulation and optical clarity
• Integrated door safety system featuring dual-seal silicone gasket, isolation-type hinge mechanism, and mechanical latch with torque-sensing engagement
• Four-tier adjustable stainless-steel shelf configuration (standard); load capacity per shelf: 15 kg (uniformly distributed)
• Dual-stage thermal protection: primary PID-controlled heating circuit + independent mechanical over-temperature limiter (cut-off at 260 °C)

Sample Compatibility & Compliance

The BAT-Series accommodates a broad spectrum of sample formats—including Petri dishes, weighing boats, crucibles, trays, and stacked industrial components—within its fully accessible chamber. Its stainless-steel construction resists corrosion from organic solvents, weak acids, and saline residues, making it suitable for ASTM D2244-compliant color stability testing, USP packaging stability studies, and ISO 9001-certified process validation workflows. The unit complies with IEC 61010-1:2010 for laboratory electrical safety and incorporates grounding continuity verification per EN 61326-1. Optional data logging (via RS485 or USB) supports 21 CFR Part 11–compliant audit trails when paired with validated PC software; all firmware revisions are version-logged and timestamped for GLP/GMP documentation integrity.

Software & Data Management

Standard operation requires no external software—parameters are configured directly via the front-panel interface. For regulated environments, optional connectivity modules enable integration into centralized lab information management systems (LIMS). The RS485 port supports Modbus RTU protocol for remote monitoring and alarm forwarding to SCADA platforms. USB data export captures time-stamped temperature profiles (sampling interval: 1–60 s configurable), stored in CSV format compatible with Excel, MATLAB, or statistical process control (SPC) tools. An optional 5-inch capacitive touchscreen controller adds graphical trend visualization, multi-step program storage (up to 16 segments), and password-protected parameter locking—meeting ALCOA+ data integrity principles for raw data preservation.

Applications

• Moisture content determination per AOAC 950.46 and ISO 5530-1
• Thermal aging of elastomers and composites (ASTM D573, ISO 188)
• Pre-drying of volumetric glassware prior to gravimetric analysis
• Curing of powder-coated substrates and printed circuit board conformal coatings
• Stabilization of hygroscopic reagents (e.g., anhydrous salts, catalysts) under inert atmosphere (when used with optional nitrogen purge kit)
• Residual solvent removal from pharmaceutical intermediates (ICH Q5C)

FAQ

What is the maximum allowable load weight for the BAT1000-DGH model?
Maximum uniformly distributed load per shelf: 15 kg. Total chamber load capacity: 60 kg (4 shelves × 15 kg), assuming even weight distribution and adequate airflow clearance (≥50 mm above/below samples).

Does the oven support validation documentation per IQ/OQ/PQ protocols?
Yes—the unit ships with a factory calibration certificate (traceable to NIM, China), and its PID controller supports user-executed sensor verification using certified reference thermometers. Optional IQ/OQ templates aligned with ISO/IEC 17025 are available upon request.

Can the BAT-Series be operated in a Class B cleanroom environment?
While not rated for ISO 5 or higher cleanrooms, its sealed chamber, non-shedding interior, and low-particulate airflow design make it suitable for ISO 7/8 support areas. HEPA-filtered air intake is available as a custom option.

Is the temperature uniformity specification verified at multiple points within the chamber?
Yes—uniformity is measured at nine locations (per ISO 17025 Annex C) using calibrated PT100 probes during final factory qualification. A full test report is included with each unit.
