Liebherr SRFfg Series Flammable Material Storage Refrigerators – Certified for Hazardous Locations with ±3 °C Stability and Auto-Defrost

The Liebherr SRFfg Performance Series is a premier line of laboratory-grade scientific refrigerators engineered explicitly for research laboratories, industrial facilities, and clinical environments that must store volatile, hazardous, or flammable chemical substances safely and compliantly. Combining spark-free ATEX-aligned inner container construction with heavy-duty laboratory architecture, these high-security units meet or exceed the absolute safety mandates of NFPA 45, NFPA 99, and Class I, Division 2, Gas Group B hazardous location certifications.

To preserve the biological and physical integrity of sensitive chemical compounds, the SRFfg series delivers an impressive temperature stability matrix limiting maximum thermal deviation to just $\pm3\text{ }^\circ\text{C}$ ($\pm3\text{ K}$) from the setpoint. Outfitted with an automated auto-defrost forced-air circulation system, it maintains a completely uniform inner climate (3 to 16 °C). In the event of a critical component malfunction, an integrated SafetyDevice instantly takes control of the physical cooling loops—stabilizing internal parameters above 2 °C to prevent accidental sample freezing, triggering robust optical and acoustic systems, and logging a specialized power failure alarm data package upon mains power restoration. Wrapped in a rugged steel external cabinet finish with a safety-enhanced self-closing solid steel door, it guarantees total workforce safety and chain-of-custody protection.

Features:

• Certified Flammable Material Safeguards
• Fully compliant with NFPA 45, NFPA 99, and Class I, Division 2, Gas Group B hazardous parameters, utilizing an explosion-proof, spark-free internal layout.
• Intelligent SafetyDevice Thermal Control
• If a technical glitch causes temperatures to fall below 2 °C, an automated secondary backup safety module engages to freeze-protect sensitive chemical samples.
• Forced-Air Distribution with Low Consumption
• An auto-defrost forced-air cooling engine maintains exceptional $\pm3\text{ }^\circ\text{C}$ climate stability while keeping operational parameters EnergyStar 2.0 efficient.
• Industrial Monochrome Touch Interface
• Features a streamlined monochrome display with sensitive touch buttons built explicitly to withstand harsh chemical wipe-downs and aggressive lab cleaning.
• SmartModule Telemetry Extension Ready
• Outfitted to accept optional plug-and-play SmartModule components for advanced WiFi, LAN, or external network remote monitoring setups.
