The Liebherr SRFvh 4011 Perfection is a full-size laboratory refrigerator designed for the safe, precise storage of temperature-sensitive samples, reagents, and pharmaceuticals. It offers a gross capacity of 420 liters (297 liters usable), spread across nine adjustable, plastic-coated wire shelves rated for 45 kg each, with a maximum total load of 225 kg. The steel cabinet, finished in white with a glass door for easy content visibility, features a commercial-grade moulded polystyrol liner built for durability and easy cleaning. Forced-air cooling and fully automatic defrosting maintain a tight temperature range of +3 °C to +16 °C, with a maximum fluctuation of just 2.4 °C — reliable performance even as ambient temperatures shift between +10 °C and +35 °C.
Safety and monitoring are core to this unit's design. A 2.4" touch-and-swipe color display enables intuitive control, while visual and audible alarms trigger immediately in the event of a malfunction. A dedicated power failure alarm activates instantly and stays active for at least 12 hours during an outage, and a volt-free alarm contact allows integration with external monitoring systems. An integrated data logger with USB interface supports HACCP-style documentation, and built-in WiFi/LAN connectivity enables remote monitoring — giving lab and healthcare staff full confidence in the integrity of stored materials.
Thoughtful details round out the unit's practicality: a vertical LED light strip recessed into the left interior wall (with its own switch) provides illumination without wasting energy, while an antimicrobial door handle supports hygienic operation in clinical settings. A mechanical lock secures access, a 10 mm access port allows for cable or probe pass-through, and the door hinges — mounted right by default — can be reversed on site for flexible installation. At 87 kg gross weight, the SRFvh 4011 Perfection delivers a dependable, energy-efficient (389 kWh/year) storage solution built for professional environments.
MAIN FEATURES:
DIN 13277 compliant
Laboratory and pharmacy refrigerators from Liebherr meet all the necessary features and performance criteria to fully comply with DIN 13277. DIN 13277 defines the requirements and test specifications for refrigerators and freezers used in laboratories and for storing medicinal products.
±2 °C temperature stability
Temperature fluctuations must be minimal to ensure that the quality of sensitive substances is preserved. Liebherr appliances have an impressive maximum deviation of just ±2 °C from the set temperature. This not only maintains the storage climate, but also the value of your stored goods.
Ultraefficient
Energy-efficient refrigerators and freezers help with ever increasing electricity prices. Liebherr fully utilises the savings potential of every component – from the compressor to the seal, to the lighting and electronics. The ultra-efficient appliances in the Perfection series for example demonstrates how this has a positive effect on your overall operating costs.
+2 °C SafetyDevice
If the temperature falls below +2 °C due to a malfunction while the temperature setting is at +5 °C or higher, the SafetyDevice takes control, stabilising the temperature, activating the alarm and protecting the contents from freezing. At colder settings, this activation threshold decreases relatively with the temperature setting.
ntegrated Wi-Fi/LAN interface
The integrated WiFi/LAN interface enables you to easily connect your appliances with Liebherr SmartMonitoring or integrate these into existing local systems.
Mechanical lock
All professional Liebherr appliances are equipped with a mechanical lock with two keys for the storage of temperature-sensitive products. This way you can be sure that no unauthorised hands can access your stored goods.
