I struggle with ice formations in my freezer. Is there a way to avoid such ice formations?

Yes. A common issue in food production and storage. Challenges with ice in sub-zero applications are well known. By controlling the humidity /dewpoint to a level below the temperature of structural elements, you’ll be able to avoid ice formations falling from the ceiling, blocking door openings, causing slippery floors, etc. By controlling for a dewpoint lower than the temperature of the cooling refrigerant, you’ll even experience frost-free evaporators and thus eliminate the need for defrosting. By controlling the humidity, you are likely to experience side effects like improved final product quality, fewer safety hazards and increased overall efficiency of the freezer.
