Overview
The LAC S400/03 is a heavy-duty, high-temperature drying oven engineered for precision thermal processing in industrial laboratories and quality control environments. Designed and manufactured in the Czech Republic, this convection oven operates on the principle of forced-air horizontal airflow—optimized to ensure uniform temperature distribution across the entire working chamber. Its robust construction, stainless steel (AISI 304) interior, and thermally stable insulation meet stringent requirements for long-term reliability in applications such as polymer curing, rubber vulcanization, powder drying, preheating of metallic components, and low-temperature annealing. With a maximum operating temperature of 300 °C and certified temperature uniformity per DIN 17052-1 Class C10-B13 (ΔT ≤ 10 °C), the S400/03 supports repeatable, auditable thermal treatments compliant with ISO 9001, ASTM D5422, and EN 60068-2-2 test protocols.
Key Features
- Stainless steel chamber (AISI 304) with reinforced corners and seamless welds—resistant to corrosion, thermal fatigue, and mechanical abrasion
- Horizontally distributed forced-air convection system ensuring consistent heat transfer and minimizing thermal stratification
- Integrated HT40AL digital controller with dual ramp/soak programming, K-type thermocouple input, and PID regulation
- Non-contact solid-state relay (SSR) for precise power modulation and extended heater life
- Mechanically interlocked door with limit switch—automatically de-energizes heating elements upon opening
- Manual air inlet and exhaust valves for controlled atmosphere management during volatile or solvent-based processes
- Standard configuration includes internal shelf support rails; optional shelves are load-rated up to 25 kg each
- Comprehensive safety architecture: independent overtemperature cut-off (OTC), thermal fuses, and grounded chassis
Sample Compatibility & Compliance
The S400/03 accommodates a wide range of sample formats—including trays, crucibles, molds, and bulk material containers—within its 380 L usable chamber volume. Its horizontal airflow design minimizes turbulence-induced displacement of lightweight samples while maintaining laminar flow patterns essential for uniform thermal exposure. The oven complies with European CE directives (2014/35/EU Low Voltage Directive and 2014/30/EU EMC Directive), and its temperature performance is validated against DIN 17052-1 for industrial ovens. Optional accessories—including HT200/HT205 programmable controllers, multi-channel digital temperature recorders, and RS232/EIA-485 interfaces—enable full traceability under GLP and GMP frameworks. Calibration certificates (traceable to PTB or NIST standards) and measurement uncertainty reports are available upon request for audit-ready documentation.
Software & Data Management
When equipped with the HT200 or HT205 controller, the S400/03 integrates seamlessly into laboratory data ecosystems via native LAN or USB connectivity. The HTMonit software suite provides real-time monitoring, remote parameter adjustment, and automated logging of temperature profiles, setpoints, and alarm events. All logged data include timestamps, user IDs, and controller firmware version metadata—supporting FDA 21 CFR Part 11 compliance when deployed with electronic signature and audit trail modules. Optional RS232 or EIA-485 serial interfaces allow integration with SCADA systems or centralized LIMS platforms. Calibration data—including thermocouple loop verification records and uniformity mapping reports—can be exported in CSV or PDF format for QA archival.
Applications
- Rubber and elastomer vulcanization per ASTM D5511 and ISO 34-1
- Curing of epoxy, phenolic, and silicone-based adhesives and coatings
- Drying of ceramic green bodies, catalyst supports, and battery electrode slurries
- Preheating of metal substrates prior to coating or bonding operations
- Moisture content determination in pharmaceutical excipients (USP <1251>)
- Aging studies of polymers and composites per ISO 188 and ASTM D573
- Thermal conditioning of calibration standards and reference materials
FAQ
What is the maximum load capacity per shelf?
Each standard shelf is rated for 25 kg uniformly distributed load; custom-reinforced shelves (optional) support up to 50 kg.
Can the oven be validated for IQ/OQ/PQ protocols?
Yes—LAC provides validation support documents, including URS templates, FAT/SAT checklists, and temperature mapping SOPs aligned with ISO 14644 and EU Annex 15.
Is the chamber pressure-rated or vacuum-capable?
No—the S400/03 is designed for ambient-pressure operation only; vacuum or overpressure modifications require factory engineering review.
How often does the temperature sensor require recalibration?
Annual calibration is recommended; the integrated K-type thermocouple supports field verification using certified reference sources per ISO/IEC 17025.
Are replacement parts and technical support available outside the EU?
Yes—LAC maintains authorized service partners in North America, APAC, and EMEA regions; spare parts inventory includes heaters, SSRs, controllers, and door gaskets with typical lead time of 4–6 weeks.
