cryologo

The CryoFreezer ™ is designed to compete with the freezer market head on, while still offering temperature uniformity using the proven construction materials of the CryoTemper™ and CryoFurnace™.  The CryoFreezer™ ranges from ambient to -300°F Standard controller settings make sure the temperature profile is followed within a specified process deviation limit, assuring the process value matches the recipe Set Point. Positive recirculation fans ensure temperature uniformity everywhere in the chamber. The use of liquid nitrogen as a cooling source keeps maintenance costs low and reduces the need for rust inhibitors and cleaning.
