ZC-1N Mobile-Cart Industrial Drying Oven

Overview

The ZC-1N Mobile-Cart Industrial Drying Oven is an engineered solution for high-capacity thermal processing in quality control laboratories, R&D facilities, and production environments requiring uniform, repeatable, and scalable drying, curing, aging, and pre-conditioning of large or heavy specimens. Designed around a forced-air convection principle, the oven utilizes a top-mounted 550 W axial fan to drive continuous air circulation through dual-side heating ducts and bottom return vents—establishing a three-dimensional airflow pattern that minimizes thermal stratification and ensures ±3% temperature uniformity across the full 1300 × 500 × 650 mm working chamber. Its structural architecture integrates a double-wall stainless steel inner chamber (SUS304), high-density glass fiber insulation in all six cavity walls, and precision-machined floor-mounted rails compatible with custom load carts—enabling safe handling of payloads exceeding 100 kg per cart without compromising thermal stability. The system operates within a validated range of ambient +5°C to 180°C, with programmable ramp-and-soak profiles supporting ISO 9001-compliant process documentation and ASTM E145–22 thermal validation protocols.

Key Features

• Stainless steel inner chamber (SUS304) with integrated floor rails for seamless cart insertion and extraction
• Dual-side heating configuration with stainless steel sheathed tubular heaters embedded in insulated side ducts
• Top-mounted high-torque axial fan (550 W) driving laminar, multi-directional airflow for rapid thermal equilibration
• LTDE programmable PID controller with 30-stage ramp/soak capability, 1°C display resolution, and automatic shutdown on timer completion
• Dual independent over-temperature protection: primary electronic cutoff at setpoint +15°C and secondary mechanical fuse at 200°C
• High-temperature silicone door gasket ensuring >95% sealing efficiency at 180°C; pressure-lock door mechanism with visual latch indication
• Comprehensive safety suite including leakage current protection, motor overcurrent cutoff, and grounded chassis design per IEC 61000-6-3 EMC standards
• Modular electrical layout with branded solid-state relays, contactors, and PT100 Class B sensor (IEC 60751) mounted via rear-access compensation wiring

Sample Compatibility & Compliance

The ZC-1N accommodates bulky or dense samples—including metal components, PCB assemblies, composite laminates, ceramic substrates, and coated industrial parts—without dimensional restriction beyond its internal volume. Its rail-guided loading system eliminates manual lifting, reducing ergonomic risk during GLP/GMP-aligned batch processing. The oven meets key regulatory prerequisites for thermal validation workflows: it supports IQ/OQ/PQ execution per FDA 21 CFR Part 11 data integrity guidelines when paired with optional audit-trail-enabled controllers; complies with ISO 17025 clause 5.4.2 for equipment suitability in accredited testing labs; and satisfies ASTM D5422–20 requirements for uniformity assessment in forced-convection ovens. All thermal performance specifications—including ±2°C fluctuation tolerance and ≤5°C/min controllable ramp rate—are verified under steady-state load conditions using NIST-traceable thermocouple mapping per ISO/IEC 17025 Annex A.4.

Software & Data Management

While the standard LTDE controller operates as a standalone hardware interface, its RS485 port enables integration into centralized laboratory information management systems (LIMS) or SCADA platforms via Modbus RTU protocol. Optional firmware upgrades support CSV export of time-stamped temperature logs (with UTC timestamps), configurable alarm event recording (e.g., door-open duration, overtemp trigger), and password-protected parameter locking for SOP enforcement. For regulated environments, third-party validation packages are available—including electronic signature support, user access level assignment (admin/operator/auditor), and 21 CFR Part 11-compliant audit trail generation with immutable storage. Calibration certificates for the PT100 sensor and controller output are provided with each unit, traceable to CNAS-accredited reference standards.

Applications

• Thermal aging of polymer-based insulators and elastomeric seals per IEC 60216 and UL 746B
• Curing of epoxy-coated electrical enclosures and powder-coated metal housings under controlled ramp profiles
• Moisture removal from hygroscopic materials prior to gravimetric analysis (ASTM D229)
• Pre-baking of semiconductor wafers and printed circuit boards to eliminate residual solvents
• Accelerated life testing of adhesives, potting compounds, and encapsulants per MIL-STD-883 Method 1008
• Stabilization of reference standards and calibration artifacts in metrology labs
• Batch conditioning of construction materials (e.g., concrete test cylinders, asphalt binders) per AASHTO T307

FAQ

What is the maximum load capacity supported by the rail system?
The floor rails are structurally rated for static loads up to 150 kg per cart; dynamic loading during insertion/removal should remain below 100 kg for operator safety and long-term rail integrity.
Can the ZC-1N be validated for GMP manufacturing use?
Yes—the oven’s construction, control architecture, and documented thermal performance meet baseline requirements for IQ/OQ execution; full GMP compliance requires site-specific PQ protocols and integration with qualified data acquisition systems.
Is external exhaust ducting required?
No—integrated top-mounted safety vent allows passive pressure equalization; however, active exhaust connection is recommended when processing volatile solvents or off-gassing materials per OSHA 1910.1200.
How is temperature uniformity verified during factory acceptance testing?
Nine-point thermocouple mapping is performed at 100°C and 150°C using calibrated Class I sensors; results are archived in the unit’s FAT report and confirm ±3% deviation across all measured zones.
Are replacement carts available with custom dimensions or load-bearing specifications?
Yes—Zhuochi offers OEM cart fabrication services aligned with ISO 2768-mK tolerances; lead time is typically 3–4 weeks from drawing approval.
