+2 °C SafetyDevice, the control mechanism automatically activates if temperatures fall below +2 °C. This prevents accidental freezing of temperature‑sensitive samples. When triggered, the system stabilizes temperature and issues an alarm so that users are notified instantly - supporting risk mitigation and sample integrity. Designed to meet DIN 13277 and IEC 61010‑2‑011. These certifications confirm stringent testing for temperature uniformity, mechanical reliability, electrical safety, and biomedical‑grade operation. The appliance maintains exceptionally stable storage conditions with ±2 °C temperature deviation, ensuring uniform performance even during busy workflows or repeated door openings. Its operating range of 3 to 16 °C supports a wide variety of general‑purpose laboratory materials.

User experience is strengthened by a modern 2.4” touch and swipe color display, offering a clear overview of temperature readings, system alarms, and settings adjustments. In the event of a power outage, an integrated alarm system activates immediately and continues for at least 12 hours, enabling staff to respond quickly to protect stored materials.

For laboratories requiring digital traceability, the SRFvh 5501 integrates seamlessly with monitoring systems through WiFi/LAN connectivity and a removable USB data logger, providing reliable documentation of temperature conditions for audits, compliance, or quality‑control processes. The field‑reversible solid door allows installation in a variety of lab configurations, while the antimicrobial handle enhances workplace hygiene.

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.
