Low-temperature freezers at -40 °C / -50 °C, only ones with two independent refrigerating systems (2 compressors + 2 evaporators) with alternating operation and completely automatic administration. The Bank freezers can also be made in conformity to this new KW standard. The KW BANK series is, in terms of safety and guarantee of preservation of biological materials at very low temperatures, the best solution, period. Ideal for the medium-to-long-term conservation of frozen plasma. Ideally used together with fast-cooling plasma freezers of the Labcool and KPFF series. Horizontal (K4054ES, K4055S, K4055ES) and vertical (K4058S, K4060S, K4062S) freezers are equipped with two completely independent and twin systems, both from an electrical and fluid dynamics point of view (each with 1 compressor, a total of 2 evaporators, so a total of 1+1=2 compressors). These two systems operate in alternation, and each is governed by the KW NEW ICE AGE CONTROL® system; each guarantees reaching -45 °C at room T ? +35 °C. Each KW NEW ICE AGE CONTROL® system interfaces with the other, knowing its status. The Bank® solution, though initially more expensive, in the end becomes the most economical as well as the safest because the duration of the motors and electromechanical components is almost doubled.
