In high-traffic or high-humidity environments, it is essential to consider additional factors when installing display cases and merchandisers. These may include selecting units with enhanced durability, corrosion-resistant materials, and advanced humidity control systems. Additionally, consider installing units with features such as automatic door closers, anti-fog coatings, and increased airflow to maintain optimal product preservation and visual appeal. Regular maintenance and inspections are also critical in these environments to ensure the longevity and performance of the units.
