When selecting a display case or merchandiser, consider factors such as the type and quantity of products to be displayed, the desired temperature and humidity range, and the available space and electrical connections. Additionally, evaluate the unit’s energy efficiency, noise level, and aesthetic appeal. It is also essential to review the manufacturer’s specifications and certifications, such as NSF or UL, to ensure compliance with relevant regulations and standards. Consulting with a professional or conducting a site survey can also help determine the most suitable unit for your specific application.
