Memmert UF TS Through-Circulation Drying Oven

Overview

The Memmert UF TS Through-Circulation Drying Oven is an industrial-grade, horizontally configured convection oven engineered for continuous thermal processing in laboratory and pilot-scale manufacturing environments. Unlike conventional static or top-down forced-air ovens, the UF TS series employs a precisely controlled horizontal through-circulation airflow architecture—air enters via calibrated side inlets, traverses the full chamber length parallel to the conveyor path, and exits through opposing side outlets. This design ensures uniform thermal exposure across large or irregularly shaped components, minimizing thermal gradients and enabling reproducible hardening of lead frames, curing of adhesive bonds, stress-relief annealing, and tempering of metallic parts. The oven’s microprocessor-based PID temperature control system maintains setpoint stability within ±0.5 °C across the entire working volume (up to 750 L), even during dynamic loading conditions. Its fully insulated double-wall construction with mineral wool insulation and seamless AISI 304 stainless steel chamber eliminates thermal bridging and supports long-term operational integrity under sustained high-temperature duty cycles up to 300 °C.

Key Features

• Four-side heated wall system with independent zone calibration ensures homogeneous heat distribution and eliminates cold spots near chamber corners or floor surfaces.
• Horizontally oriented through-circulation airflow, adjustable from 0.1 to 1.2 m/s, optimized for convective heat transfer efficiency and process repeatability.
• Double-glazed observation windows (front and rear) with low-emissivity coated glass provide real-time visual monitoring without compromising thermal integrity or safety.
• Side-mounted conveyor interface compatible with standard industrial belt widths (up to 600 mm); optional in-chamber roller track system enables manual or semi-automated part handling for non-belted workflows.
• Robust chamber construction using fully welded AISI 304 stainless steel—electropolished interior surface resists corrosion, facilitates cleaning, and complies with ISO 14644-1 Class 7 cleanroom-compatible maintenance protocols.
• Integrated door-seal monitoring and overtemperature cut-off circuitry meet EN 61000-6-2/6-4 electromagnetic compatibility and EN 61010-1 safety requirements for Class II laboratory equipment.

Sample Compatibility & Compliance

The UF TS series accommodates diverse sample formats including PCB lead frames, encapsulated semiconductor modules, composite laminates, powder-coated metal assemblies, and polymer-molded components. Its large internal volume (160–750 L), combined with unrestricted horizontal access, supports batch sizes ranging from single trays to continuous 24/7 production lines. The oven conforms to DIN EN 60068-2-2 (dry heat testing), ASTM E145-22 (standard specification for gravity-convection and forced-ventilation ovens), and VDI/VDE 2655 Part 2 (temperature uniformity validation for industrial drying systems). All models are supplied with factory calibration certificates traceable to PTB (Physikalisch-Technische Bundesanstalt), and support IQ/OQ documentation packages for GLP, GMP, and ISO 9001-compliant quality systems.

Software & Data Management

Equipped with Memmert’s proprietary PTP-2000 control platform, the UF TS features a 7-inch capacitive touchscreen HMI with multilingual UI (English, German, French, Chinese), real-time graphing of chamber temperature vs. time, and configurable alarm thresholds for deviation, door open duration, and fan failure. Data logging is performed at user-defined intervals (1–600 seconds) and stored internally (≥100 days of 1-second data) or exported via USB 2.0 to CSV. Optional Ethernet connectivity enables integration into LabVantage, Siemens Desigo, or DeltaV DCS environments. Audit trail functionality—including operator ID, parameter changes, and event timestamps—satisfies FDA 21 CFR Part 11 requirements when paired with network-authenticated user accounts and digital signature modules.

Applications

• Thermal stabilization and moisture removal of hygroscopic electronic substrates prior to wire bonding.
• Controlled ramp-and-soak cycles for epoxy-based adhesive curing in automotive sensor assembly.
• Stress-relief annealing of machined aluminum housings used in aerospace avionics enclosures.
• Pre-bake conditioning of ceramic green tapes in MLCC (multilayer ceramic capacitor) manufacturing.
• Validation of shelf-life acceleration studies per ICH Q1A(R3) guidelines for pharmaceutical packaging materials.
• Residual solvent evaporation from solvent-cast polymer films under nitrogen-purged operation (optional accessory).

FAQ

Does the UF TS support nitrogen inerting or other gas purge configurations?
Yes—models can be equipped with standardized gas inlet/outlet ports (¼” VCR fittings), mass flow controllers, and O₂ analyzers for inert atmosphere operation; custom purge manifold integration is available upon request.
What validation documentation is included with shipment?
Each unit ships with a Factory Acceptance Test (FAT) report, temperature uniformity mapping data (per VDI/VDE 2655), and a PTB-traceable calibration certificate for the primary Pt100 sensor.
Can the UF TS be integrated into a MES or SCADA system?
Yes—via Modbus TCP/IP or OPC UA protocol support; Memmert provides detailed register maps and driver templates for Siemens, Rockwell, and Wonderware platforms.
Is the chamber accessible from both ends for true inline processing?
The UF TS is designed exclusively for horizontal through-feed operation; front and rear doors are sealed observation windows only—material ingress/egress occurs solely via side-mounted conveyor interfaces.
How often does the system require recalibration per ISO/IEC 17025 recommendations?
Annual verification is recommended; Memmert-certified service engineers perform on-site sensor recalibration, airflow profiling, and uniformity revalidation using accredited reference standards.
