Overview
The LAC S Series Industrial Drying Oven is a precision-engineered, CE-compliant forced-air convection oven designed for rigorous thermal processing in research laboratories, quality control environments, and industrial manufacturing facilities. Built in the Czech Republic to DIN 12880 and EN 61000-6-3 standards, it delivers stable, repeatable thermal conditions across its operating range of 200 °C to 300 °C—optimized for applications requiring controlled thermal exposure without inert atmosphere or vacuum capability. Its dual-side resistive heating architecture ensures rapid heat-up times and minimal thermal gradient across the working chamber, while the robust low-carbon steel frame and stainless-steel flame-tight inner chamber provide long-term structural integrity and corrosion resistance under repeated thermal cycling. The oven operates on standard three-phase industrial power and integrates seamlessly into regulated workflows compliant with ISO/IEC 17025, GLP, and GMP frameworks.
Key Features
- High-stability temperature control with ±1 °C uniformity across the full chamber volume, verified per ASTM E2209 and EN 60068-3-5
- Dual-side mounted NiCr resistance wire heating elements for symmetrical heat distribution and minimized hot-spot formation
- Modular air circulation: axial fan (S60/S100 models) or centralized recirculation ducting (S250/S400), both supporting adjustable airflow via manual damper valve
- HT40AL microprocessor controller with 30 user-programmable thermal profiles; each profile supports ≥15 time–temperature steps, real-time clock scheduling, and automatic start/stop sequencing
- Redundant safety architecture: independent mechanical overtemperature limiter (HT40AL), terminal safety switch, thermal overtravel cut-off, and non-contact solid-state relay output
- Stainless-steel flame-tight inner chamber with removable, load-rated shelves (15–25 kg/shelf; floor load capacity up to 70 kg); all internal surfaces electropolished for easy cleaning and residue resistance
- Left-hinged, clamp-latched door with high-temperature silicone gasket and ceramic rope seal—rated for continuous operation at 300 °C
Sample Compatibility & Compliance
The LAC S Series accommodates a broad spectrum of thermally stable materials including polymer films, elastomeric components, ceramic green bodies, glass substrates, electrical insulation coatings, and powder metallurgy preforms. Its chamber geometry and airflow design support uniform drying of stacked or layered samples without edge overheating or convective shadowing. All units are supplied with K-type thermocouple calibration points traceable to NIST standards and include documentation supporting IQ/OQ validation protocols. The oven meets EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EU, and carries CE marking for use within the European Economic Area. Optional accessories—including humidity sensors, METREX gas analyzers, and PC-linked data loggers—enable compliance with FDA 21 CFR Part 11 when paired with validated software environments.
Software & Data Management
While the base HT40AL controller operates as a standalone embedded system, optional RS485 or USB interfaces enable integration with laboratory information management systems (LIMS) and SCADA platforms. The PC interface module supports Modbus RTU protocol and allows remote parameter setting, real-time temperature monitoring, and export of timestamped CSV logs with audit trail metadata. When configured with the chart temperature recorder or third-party data acquisition hardware, the system satisfies ALCOA+ data integrity principles—including attributable, legible, contemporaneous, original, and accurate recordkeeping—as required by ISO/IEC 17025 Clause 7.5 and EU Annex 11. Firmware updates are delivered via secure offline methods to maintain regulatory compliance during operational use.
Applications
- Pre-drying of ceramic and composite green parts prior to sintering or firing cycles
- Curing of epoxy, silicone, and polyurethane encapsulants in electronics assembly
- Moisture removal from hygroscopic polymers and battery electrode slurries
- Thermal conditioning of rubber compounds and vulcanization preheating
- Stabilization annealing of thin-film photovoltaic substrates
- Accelerated aging studies per IEC 60068-2-2 and ASTM D573
- Post-processing bake-out of machined metal components to eliminate residual machining oils
FAQ
What is the maximum allowable load weight per shelf in the S250 model?
Each shelf supports up to 25 kg; the chamber floor is rated for 70 kg distributed load.
Is the oven compatible with nitrogen purging or inert gas operation?
No—the S Series is designed exclusively for ambient-air convection. For inert atmosphere applications, consult the LAC N series or custom-engineered variants.
Can the controller store ramp-soak profiles with dwell times less than one minute?
Yes—the HT40AL supports minimum step durations of 1 minute; sub-minute resolution requires external PLC integration.
Does the unit include factory calibration documentation?
Yes—each oven ships with a traceable calibration certificate covering chamber uniformity, temperature accuracy, and controller response time.
What maintenance intervals are recommended for the axial fan and heating elements?
Fan bearings require inspection every 1,500 operating hours; resistance wires should be visually inspected annually for oxidation or deformation—no scheduled replacement interval is specified under normal use.
