What is the difference between a cold room, a freezer room, a walk-in fridge, and a walk-in freezer?

Cold room is the common term which can encompass both cold rooms, freezer rooms, walk-in fridges, and walk-in freezers. However, the terms can be divided into two functions.

Cold rooms
A cold room, also known as a walk-in fridge or walk-in cooler, is basically a room for cooling. It will maintain a chilled, but positive temperature internally.

Freezer rooms
A freezer room or walk-in freezer is, on the other hand, a room which maintains a negative temperature internally.

What are cold rooms used for?

Cold rooms and freezer rooms serve a variety of purposes, primarily in the bulk storage of products that require specified temperatures. The breadth of items that can be stored in cold rooms include:

• Fresh produce: vegetables, fruits, dairy products, and meat
• Prepared foods: food-preps in restaurants and cafes, or sandwiches and ready meals in retail shops
• Frozen food items: meat, produce, ice cream, and bread
• Flora: plants and flowers
• Beverages: for quality retention or perfect serving temperatures

The versatility of cold rooms and freezer rooms can cater to a range of different commercial requirements and the list could go on and on.
