Introduction

In supermarket refrigeration, temperature control often receives the most attention, but humidity management is just as critical especially during overnight operations. When covers are applied to open display cases, the internal environment becomes more enclosed, changing how moisture behaves inside the system. Poor humidity control is a hidden factor behind why fresh food loses quality overnight, particularly in produce and deli sections.

Understanding how humidity interacts with refrigeration covers helps retailers protect product quality, reduce spoilage, and improve overall system efficiency.

1. The Role of Humidity in Food Preservation

Humidity directly affects how food retains moisture, texture, and visual appeal. Fresh produce requires higher humidity to prevent dehydration, while deli products need controlled conditions to avoid condensation and bacterial growth.

When humidity is not properly managed:

• Produce loses moisture and becomes wilted
• Deli items develop surface condensation
• Product appearance deteriorates quickly

These effects contribute to temperature causing food spoilage in supermarket, even when cooling systems are functioning correctly.

2. How Night Covers Change the Internal Environment

Applying covers to refrigerated cases reduces airflow exchange with the surrounding environment. While this helps retain cold air, it also traps moisture inside the case.
