Walk-in freezers are big cold storage units with ample space. These facilities are ideal for businesses with large turnover that need to store a significant quantity of perishable goods for longer timeframes.

Walk-in Freezer vs Walk-in Chiller: What’s the Difference?

We often hear about walk-in chillers and freezers. Essentially, they are similar in function with the key difference being the storage temperature that is maintained within the unit:
–       Walk-in coolers maintain a temperature between +2°C and +8°C for the storage of perishable products such as processed food and beverages
–       Walk-in freezers, alternatively, operate within a temperature range of -12° C to -18° C, primarily used for holding items such as frozen products

How to Select the Right Walk-in Freezer for Your Business

Nature of business

A small business such as a restaurant would benefit from a small setup as compared to a processed food industry

Freezing conditions

Different products have different freezing requirements. Factors such as temperature range, cooling or freezing speed, and a combination of freezer cum chiller units should be considered as per business requirements.

Volume of products

The size and storage space of freezers entirely depends on the volume of stocks required to be stored. More stock needs more storage space.

Delivery frequency

Frequent delivery of fresh products implies that they are fast-moving. They might not need large freezers but they would need an efficient racking system for storage and stock rotation


Walk-in refrigerators have slowly become indispensable for every industry that deals with perishable goods and temperature-sensitive products. Whether it is for long-term storage, maintaining the integrity of the product or extending their shelf life, walk-in freezers have now become the backbone of both small and large businesses.
