LAC S400/02 Heavy-Duty High-Temperature Drying Oven

Overview

The LAC S400/02 is a heavy-duty, high-temperature drying oven engineered for precision thermal processing in industrial R&D laboratories, quality control environments, and production-scale validation workflows. Designed and manufactured in the Czech Republic by LAC s.r.o., a long-standing specialist in industrial thermal equipment, this oven operates on the principle of forced-air convection with horizontally optimized airflow—ensuring uniform heat distribution across the entire working volume. Its operational temperature range spans 60 °C to 300 °C, making it suitable for applications including moisture removal, polymer curing, rubber vulcanization preheating, catalyst activation, powder drying, and low-temperature annealing of metallic or ceramic substrates. The stainless steel (AISI 304) chamber provides exceptional resistance to oxidation, corrosion, and mechanical wear under repeated thermal cycling, while its robust structural frame supports long-term stability in continuous-use settings.

Key Features

• Stainless steel interior chamber (800 × 800 × 600 mm) with seamless welded construction and polished finish for easy cleaning and contamination control
• Horizontally balanced forced-air circulation system with adjustable fan speed and directional ducting to minimize thermal stratification
• High-reliability heating elements integrated into the chamber walls and rear plenum, delivering consistent thermal input without hot-spot formation
• Standard HT40AL digital controller with dual ramp-and-soak capability, real-time temperature display, and manual air inlet/exhaust valves
• Mechanically interlocked door with limit switch for safety-critical power cutoff during opening
• Integrated K-type thermocouple with traceable calibration certificate; optional three-channel digital temperature recorder available for audit-ready data logging
• Compliance-ready architecture: designed to support GLP/GMP-aligned validation protocols—including IQ/OQ/PQ documentation packages and temperature mapping per ISO/IEC 17025 requirements

Sample Compatibility & Compliance

The S400/02 accommodates a broad spectrum of sample formats—from standard Petri dishes and crucibles to large composite panels (up to 750 mm × 750 mm footprint) and stacked industrial molds. Its spacious internal volume (380 L) and vertical clearance allow for multi-tiered rack configurations using standardized stainless steel shelves (included). The oven meets DIN 17052-1 Class C10–B13 specifications for temperature uniformity (ΔT ≤ 10 °C across load zone at 200 °C), verified via calibrated sensor arrays and documented in accordance with ASTM E2207 and EN 60068-3-5. Optional accessories—including HT200/HT205 programmable controllers with LAN/USB interfaces, automatic venting actuators, and exhaust chimneys with flow-diverting dampers—enable full integration into regulated environments requiring FDA 21 CFR Part 11–compliant electronic records and audit trails.

Software & Data Management

While the base HT40AL controller offers standalone operation, the HT200 and HT205 upgrade options provide comprehensive process automation and data governance. The HT200 supports up to 30 independent programs (25 steps each), with time- and temperature-triggered events, data export via USB or Ethernet, and RS485/EIA-485 serial communication for SCADA integration. The HT205 adds LAN-based remote monitoring and synchronization with HTMonit software—a validated platform supporting CSV/Excel export, real-time graphing, alarm history, and electronic signature functionality compliant with 21 CFR Part 11 Annex 11. All controllers accept external thermocouple inputs for independent verification, and optional three-channel digital recorders include NIST-traceable calibration certificates and timestamped event logs compatible with LIMS and ELN systems.

Applications

• Pre-drying of hygroscopic powders (e.g., lithium-ion battery cathode materials, pharmaceutical excipients) prior to XRD or TGA analysis
• Curing of epoxy resins and silicone elastomers in automotive and aerospace component manufacturing
• Vulcanization preheating of rubber compounds in tire R&D labs, aligned with ASTM D572 and ISO 1431 test standards
• Thermal stabilization of ceramic green bodies before sintering
• Residual solvent removal from coated metal substrates in electronics packaging QA
• Accelerated aging studies per ISO 11341 and ASTM G154 for UV/weathering test specimen conditioning

FAQ

What is the maximum operating temperature, and is it certified for continuous use at 300 °C?
Yes—the S400/02 is rated for continuous operation at 300 °C. Its insulation, gasketing, and electrical components are selected and tested per EN 60519-2 for Class H (180 °C) and extended-duty thermal endurance.
Can the oven be validated for GMP compliance?
Yes. LAC provides IQ/OQ documentation templates, temperature mapping protocols, and calibration support files. Optional accessories—including HT200/HT205 controllers with 21 CFR Part 11 mode—enable full electronic audit trail generation.
Is horizontal airflow essential for my application involving stacked trays?
Yes. Unlike vertical convection ovens, the S400/02’s horizontal airflow design minimizes vertical thermal gradients, ensuring ±1 °C uniformity across all shelf levels—even with full 380 L loading.
What safety certifications does the unit carry?
It complies with CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU, and conforms to EN 61000-6-3 (emissions) and EN 61000-6-4 (immunity).
Are replacement parts and service support available outside the EU?
LAC maintains an international distributor network with technical support centers in North America, APAC, and EMEA. Spare parts—including heaters, fans, controllers, and gaskets—are stocked regionally with lead times under 10 business days.
