As natural as nitrogen
CUMULUS® uses liquid nitrogen (LIN) as the cooling agent to achieve ultra-low temperatures and near-linear cooling rates unattainable with compressor systems.
A cryogenic heat exchanger system converts LIN into cold nitrogen gas, then used to independently cool both the shelves and the ice condenser within the freeze-drying chamber.
The heat transfer fluid circulating inside each shelf is cooled by cold nitrogen gas rather than liquid nitrogen. Meanwhile, the ice condenser coils are cooled directly by cold nitrogen gas, which is evenly distributed to eliminate the risk of large temperature gradients across the coils.
