Finding the right refrigerator for your storage needs

At Teknomek, we understand the importance of reliable equipment you can trust. When it comes to the storage of food and high-risk items, there should be no room for error. Whether your priority is precise temperature control for sensitive samples or practical, easy-to-clean interiors for food storage, our refrigeration solutions are built to help you work efficiently, safely, and in full compliance with industry standards. In this blog, we explore the distinctions between our Liebherr’ Performance & Perfection collections to help you identify which appliance is best suited to your storage needs. 

Versatile designs, outstanding precision 

From undercounter to freestanding and combination designs, we offer a variety of Liebherr refrigerators and freezers to suit both your storage requirements and room layout. These appliances belong to Liebherr’s two collections: ‘Performance’ and ‘Perfection’.  

While both are robust and reliable, the Perfection refrigerator range provides improved temperature stability with fluctuations of ±2°C compared to the Performance collections’ ±3°C. This, alongside the Perfection range’s 12-hour back up battery for protection against power failure, make the Liebherr Perfection appliances a perfect choice for critical lab settings and use in the life science or pharmaceutical sectors. 

Hygienic interior 

Depending on which collection you choose, our fridges are supplied with either a stainless steel or polystyrol interior. The moulded polystyrol liner is ideal for food storage as it offers an easy to clean interior that shows up dirt and debris with curved corners to prevent dirt traps from forming. In comparison, our lab refrigeration range features a chrome-nickel steel interior (AISI 304) for heightened corrosion resistance and durability. 

For cleanroom environments, Teknomek also offers spark-free ATEX models to ensure the safe storage of volatile materials.  

Finding the right cooling system 

Teknomek’s refrigeration range features two types of cooling systems - forced air and fan-assisted.  These both use fans to improve temperature distribution but forced air systems push chilled air more powerfully throughout the interior, providing more consistent temperatures and rapid recovery after the door is opened. This makes forced-air systems ideal for temperature-critical lab samples or high-risk foods under strict HACCP control.  

Fan-assisted systems provide gentler air circulation compared to forced-air appliances. These still improve temperature consistency over models relying on static cooling methods, but can result in slightly greater temperature variation depending on how tightly packed items are stored.  

With this in mind, we would recommend forced air systems for any environment needing maximum precision or consistency, whereas fan-assisted can be better for gentle, efficient cooling in situations where minor fluctuations are acceptable.  

Expert insight with smart monitoring 

Many of Teknomek’s Liebherr Perfection fridges and freezers feature integrated data loggers with USB export, providing audit-ready records to meet regulatory requirements. This continuous monitoring not only safeguards sensitive lab samples or high-risk foods, but also reduces the need for manual temperature checks, saving time while enhancing traceability and peace of mind. Equipped with connectivity options such as WLAN or LAN via the Liebherr SmartModule, these units can share real-time temperature data to monitoring systems for remote supervision and provide instant alerts if temperatures move outside set limits.
