Freezer vs. Chiller — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on April 26, 2024
Freezers maintain temperatures below 0°C to preserve food by freezing, while chillers keep food just above freezing to retard spoilage without freezing.

Key Differences
Freezers are designed to store food at temperatures below 0°C, effectively freezing water content and preserving items for extended periods. In contrast, chillers operate at temperatures just above 0°C to 5°C, ideal for keeping food fresh without freezing it.
The function of a freezer is to slow down bacterial growth by solidifying water into ice, which makes it unsuitable for bacteria. Chillers, on the other hand, merely slow bacterial activity by maintaining a cold, but not freezing, environment.
Freezers are commonly used for storing frozen products like meat, vegetables, and prepared meals for months. Chillers are better suited for items like dairy, fresh vegetables, and drinks that need short-term cooling without the risk of frost damage.
The energy consumption of freezers is generally higher due to the need to maintain lower temperatures. Chillers consume less energy because the temperature requirements are not as stringent.
In terms of appliance design, freezers often come with insulated walls and doors to prevent heat exchange and maintain stable internal temperatures. Chillers may have less insulation because the temperature differential between the inside and the outside environment is smaller.

Compare with Definitions
Freezer
An appliance for long-term food preservation.
Our freezer is full of frozen fruits and vegetables.
Chiller
A device used to maintain a slightly cold temperature.
The chiller keeps the beer perfectly cold.
Freezer
A device that keeps its contents below freezing point.
We stored the surplus meat in the freezer for future use.
Chiller
Essential for items that must not freeze.
The chiller is set just above freezing to protect the delicate herbs.
Freezer
A compartment in a refrigerator for freezing food.
She placed the ice cream in the freezer compartment.
Chiller
Commonly used for storing perishable food items.
Place the fresh juice in the chiller to keep it fresh.
Freezer
Used in commercial settings for bulk storage.
The restaurant’s freezer can hold up to 500 kilograms of produce.
Chiller
An appliance found in kitchens and bars.
Our chiller broke down, and we need to replace it soon.
Freezer
An industrial unit designed to freeze large quantities.
The factory installed a new freezer to increase its storage capacity.
Chiller
Utilizes less energy compared to freezers.
Upgrading to a more efficient chiller helped reduce our electricity bill.
Freezer
A thermally insulated compartment, cabinet, or room in which a subfreezing temperature is maintained for the rapid freezing and storing of perishable items, especially food.
Chiller
A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water).
Freezer
An appliance or room used to store food or other perishable items at temperatures below 0° Celsius (32° Fahrenheit).
Chiller
One that chills.
Freezer
The section of a refrigerator used to store food or other perishable items at a temperature below 0° Celsius (32° Fahrenheit).
Chiller
A frightening story, especially one involving violence, evil, or the supernatural; a thriller.
Freezer

Chiller
Something that chills
Freezer

Chiller
A machine that produces cold air, either for air conditioning, to prepare chilled foods etc.
Freezer
Electric refrigerator (trade name Deepfreeze) in which food is frozen and stored for long periods of time
Chiller
A heat exchanger between a coolant and a refrigerant, to transfer heat from the coolant loop into the refrigeration system
Chiller
A machine that removes heat from the working fluid in a refrigeration cycle
Chiller
A frightening dramatic work, such as a book or film
Chiller
Excitation that makes your hair stand up or that chills your bones;

Common Curiosities
Can I store ice cream in a chiller?
No, ice cream needs to be stored in a freezer as it requires temperatures below freezing.
Is a chiller suitable for storing meat long-term?
No, for long-term storage, meat should be kept in a freezer to prevent spoilage.
Are there different types of freezers?
Yes, there are several types of freezers including upright freezers, chest freezers, and drawer freezers, each designed for different storage needs and space considerations.
What should not be stored in a chiller?
Items that require freezing to remain safe and edible, such as raw meats, seafood, and certain desserts like ice cream, should not be stored in a chiller.
Can a chiller freeze food if set to a very low temperature?
Chillers are not designed to reach temperatures low enough to freeze food; they are meant to keep food just above freezing.
What temperature does a freezer typically operate at?
A freezer typically operates at temperatures below 0°C.
Can I convert a freezer into a chiller?
Converting a freezer into a chiller is technically possible with proper adjustments to the thermostat, but it might not be ideal depending on the model.
What is the primary purpose of a chiller in commercial settings?
In commercial settings, a chiller is primarily used to keep beverages and perishable foods at a safe, cool temperature without freezing, ideal for restaurants and bars.
Which is more energy-efficient, a freezer or a chiller?
Chillers are generally more energy-efficient than freezers because they do not need to maintain as low temperatures.
How do the costs of operating a freezer and chiller compare?
Generally, operating a freezer is more costly than a chiller due to higher energy demands for maintaining lower temperatures.
What maintenance is required for freezers and chillers?
Both freezers and chillers require regular maintenance, including cleaning, checking door seals, and ensuring that the temperature control is functioning correctly.
How long can food be stored in a freezer compared to a chiller?
Food can be stored in a freezer for several months up to a year depending on the item, while in a chiller, food should generally only be stored for a few days to a week.
What are the environmental impacts of freezers and chillers?
Both freezers and chillers impact the environment due to their energy usage. Choosing energy-efficient models and maintaining proper settings can help reduce their environmental footprint.
Is it possible to adjust the temperature of a chiller to act like a freezer?
No, chillers are not capable of reaching the low temperatures required for freezing, as their design and compressor are intended for milder cooling.
