Our standard freezers will accommodate a -20°C set-point with a control tolerance ±0.5°C, or better. Many are custom-engineered for a wide variety of applications, including freeze-thaw test regimens in accordance with ASTM C666, GMP stability storage from 4°C to -30°C, wide-range test material test chambers, and mortuary/cadaver storage freezers. Our freezer rooms are typically supplied with desiccant or refrigeration based dehumidification in order to maintain a low dew-point and prevent ice accumulation on both product and equipment surfaces.
