I ♥ twice the sample security

You want the ultimate security for stable and reliable storage of your extremely valuable samples. We provide double the safety by design. TwinGuard’s Dual Cooling system differs significantly from conventional cascade refrigeration technology. In Dual Cool systems, two independent refrigeration systems reliably maintain an ultra-low temperature environment, even if an unexpected failure should occur in one cooling circuit, the other can maintain the freezer in the -70ºC range until service can be arranged. This level of ultra-low temperature back-up cannot be achieved by conventional cascade systems.

The unique functionality is achieved through the use of two, completely independent, auto-cascade systems – the compressors, evaporators and cooling fans of the two systems operate separately from each other. Two efficient evaporator circuits surround the interior chamber in a strategically-designed arrangement to ensure the highest levels of temperature uniformity with either one, or both of the refrigeration systems functioning.
