The TF-B150-460W is a ruggedised, ultra-low temperature industrial freezer designed for demanding environments. With a 460L capacity and the ability to freeze up to 80kg of material to -145°C in just 15 hours at an ambient temperature of 40°C, this unit is perfect for industrial applications requiring reliable, high-performance freezing. It can operate in temperatures up to 50°C ambient, with extended freezing times of approximately 24 hours to -145°C. At 30°C ambient, it can achieve -145°C in just 12 hours, and the empty chamber freezes even faster.
