Liebherr SFTvh 1501 Perfection laboratory freezer with convection cooling
This laboratory freezer offers reliable storage of temperature-sensitive samples, reagents and other substances thanks to convection cooling and modern NoFrost technology. The robust design and energy-efficient construction make it particularly interesting for laboratory environments where constant freezer temperatures, durability and easy maintenance are required. Compared to similar products on the market, this model scores points with its DIN 13277 compliance, integrated monitoring systems and sophisticated alarm management, which significantly increase the protection of valuable materials.
Reliable cooling and sophisticated functions
A key strength of this freezer is the NoFrost principle: it prevents the formation of ice in the interior by dissipating moisture using circulating air and removing it from the appliance via demand-controlled defrosting phases. This completely eliminates the need for manual defrosting, which not only saves time in everyday laboratory work, but also reduces the risk of temperature fluctuations. In addition, the wide temperature range of -9 °C to -35 °C allows flexible application planning, for example for the safe storage of microbiological samples or temperature-sensitive substances such as enzymes or vaccines.
The integrated WiFi/LAN interface enables convenient networking with a monitoring system. In conjunction with SmartMonitoring, the temperature level can be continuously monitored and recorded. An alarm history documents any faults or deviations that occur, which is essential for seamless quality control and traceability. Equally important is the mechanical lock with two keys to prevent unauthorized access. The appliance also has a self-closing door, which makes it virtually impossible to accidentally leave the freezer compartments open.
Important technical features at a glance
- Gross capacity: 103 liters
- Adjustable temperature range: -9 °C to -35 °C
- Energy consumption (24 hours): 0.512 kWh/24h
- Refrigerant: R 600a (environmentally friendly and efficient)
- Defrosting process: Automatic (NoFrost)
- Alarm options: Visual and audible, plus alarm history
In addition, the side panels, door and adjustable feet are made of high-quality metal components to withstand the stresses and strains of everyday laboratory use with ease. The interior is made of robust and odorless plastic, which is easy to clean thanks to its seamless finish - a decisive factor for hygiene and cleanroom suitability.
The cooling and heating times are optimized so that the required set temperature is restored very quickly after the door is opened. Among other things, this is ensured by the dynamic cooling system, the interaction with the recirculation fan and the intelligent control system. This control system is intuitively accessible to authorized specialist personnel via the touch & swipe interface seamlessly integrated into the door. Important functions can be adjusted with password protection to effectively prevent tampering and operating errors.
Certifications and standards
The device was specially developed for laboratories and meets the following requirements, among others:

- Storage of temperature-sensitive electrodes, materials or polymer samples that need to remain intact
Frequently asked questions
How does NoFrost technology help in everyday practice?
It prevents ice and frost forming in the interior with the help of active air circulation and adapted defrosting phases. This eliminates the need for manual defrosting processes, which saves working time and ensures reliable temperature stability.
What are the benefits of the integrated data logger?
The data logger stores the temperature profile, alarm history and service information directly in the appliance for up to five years. This enables complete traceability without the need to integrate external systems. This makes internal and external audits easier.
Can the door hinge be changed?
Yes, the door hinge is on the right at the factory, but can be changed to the left side without additional accessories. This process is easy to carry out and increases flexibility in terms of installation if required.
Conclusion
The freezer presented here impresses with its energy-efficient operation, reliable temperature stability and short cooling times. With the help of automatic defrosting and integrated monitoring functions, it reduces the potential for errors and ensures complete documentation of all cooling processes. At the same time, the intuitive touch control panel and the mechanical locking mechanism make it easier to organize the laboratory. Anyone looking for a durable, DIN-compliant and technically sophisticated deep-freeze system will find this appliance to be an excellent solution for professional laboratory applications.
