4.7 cubic‑foot Undercounter scientific refrigerator is a compact, energy‑efficient, laboratory‑grade cold‑storage solution engineered for high‑performance professional environments. Its space‑saving design allows seamless installation beneath laboratory benches or flexible use as a freestanding unit.

• Ultra‑efficient energy performance (ENERGY STAR® 2.0)
• +2 °C SafetyDevice - Freeze Prevention System
• ±2 °C temperature stability
• Compact undercounter format (4.7 cu. ft.)
• Digital controller
• Adjustable storage with high load capacity
• LED lighting column
• Field‑reversible solid door
• All units are supplied with a 3-year manufacturer's parts and labor warranty and a 5-year manufacturer's compressor parts warranty

Models are available in both perfection and performance series. The choice of temperature stability, tested to EN 60068-3, important when it comes to validating appliances to user application or requirements. Both Perfection and Performance series have calibration function.

Perfection series ±2 K deviation from setpoint and DIN 13277 compliance. Performance series with ±3 K deviation from setpoint. Perfection series give maximum content security: Alarm with battery backup (12 h) immediately upon power failure, alarm history (10 events) and integrated data logger with real-time clock. Perfection series has integrated LAN/WiFi or local API for continuous monitoring and with USB interface for reading the data logger.

Performance series with ±3 K deviation from setpoint. Performance models feature Power failure alarm when mains power returns and have optional LAN/WiFi interfaces and local API (optional via SmartModule as accessory).

Certifications: IEC 61010-2-011 standard refrigerators specially developed for storing temperature-sensitive products are CE safety-compliant. This ensures that all mechanical and electrical requirements for injury-free operation are met and that the team are always safe. Perfection series comply with DIN 13277.
EnergyStar 2.0 certified.

Accessories information: Wire shelves with 45 kg shelf load, perforated sheet-metal shelves available as accessory for storing small items.

Ordering information: Accessories are not included (these must be ordered separately).

Features:

• Space-Saving Undercounter Geometry Engineered with a compact, ultra-efficient structural footprint that installs perfectly flush beneath standard laboratory workstations or benches.
• +2 °C SafetyDevice Freeze Prevention An automated internal failsafe module independently assumes control of the cooling loop if temperatures drop too low, safeguarding sensitive biological specimens.
• Dual Performance Segmentation Options Choose between the maximum security of the Perfection series (integrated logging, 12-hour instant backup battery) or the streamlined efficiency of the Performance series.
• Advanced Multi-Interface Data Logging The Perfection line features native LAN/WiFi connectivity, a local tracking API, and a clean USB interface for rapid calibration audit reporting.
• High-Load Wire Shelf Matrix Includes 4 individually adjustable wire shelves that boast a heavy-duty 45 kg load capacity per shelf, resisting sagging under dense sample sets.
