Walk-in cold rooms typically maintain temperatures between 35°F and 41°F (1.6°C–5°C) for cooler applications, and -10°F to 0°F (-23°C to -18°C) for freezer applications. Pharmaceutical and specialty freezers may operate at -20°C or -40°C. The exact temperature depends on the refrigeration unit paired with the box and the intended storage product.
