Walk-in Freezer
Walk-in freezers are the ideal solution for business premises that require larger, more adaptable frozen storage areas.
Their capacity and reliable temperature control between -1 and -40°C make them the go-to choice for a wide range of industries and businesses.
What is a Walk-In Freezer?
Compared to commercial freezers, which offer very limited storage capacity and a limited array of storage orientations, a walk-in freezer is an insulated room or space that maintains negative temperatures (below 0 degrees Celsius) with a much larger capacity.
While walk-in fridges (also referred to as walk-in chillers) maintain positive chilled temperatures, walk-in freezers can be used in a variety of applications to keep goods at predictable minus temperatures, including:
- Food and drink manufacture, storage, and retail
- Eateries like hotels and restaurants
- Pharmaceutical, healthcare, and medical establishments
- Warehousing and distribution
Plus, many more!

Types of Walk-In Freezers
Walk-in freezers, also referred to as freezer cold rooms or freezer rooms, are generally used to keep already frozen products frozen or to freeze chilled/ambient products.
Depending on your requirements, MTCSS can design and install one of the following industrial walk-in freezer types, so you have the functionality and space you need for day-to-day operations. This includes:
- Holding Freezer Cold Rooms – Which are used to store already frozen products and keep them at the right temperature to stop defrosting
- Pull-Down Freezer Cold Rooms – This type of walk-in freezer can freeze chilled or ambient products to make them suitable for extended storage
- Blast Freezer Cold Rooms – These use more powerful refrigeration systems to freeze chilled and ambient products quicker than a pull-down freezer, offering superior preservation of food quality, texture, and nutrients
Benefits of a Commercial Walk-In Freezer
There are many benefits of a walk-in commercial cold room freezer, which make them a popular upgrade for businesses across the country, such as:
Superior temperature control
With consistent and precise temperature maintenance, plus the ability to add alarms if recorded temperatures change, the quality and safety of goods are protected, and their lifespan is maintained.
Vastly increased storage capacity and flexibility
An under-counter or even free-standing commercial freezer often comes with a limited capacity of around a couple of hundred litres. Walk-in freezer rooms can competently handle tens of thousands of litres, in any layout needed for your current and future stock levels.
Improved accessibility
Allowing staff to easily enter, restock, and even use wheeled machinery like forklifts with space to manoeuvre, getting what they need is simple and fast.
Unmatched energy efficiency
Thanks to specially designed freezer components and their air-tight design, running one cold room is much more energy efficient than multiple standalone units – saving you valuable money on your energy bills!
Increased customisation and longevity
Designed bespoke to your needs from the outset, walk-in freezer rooms will meet your business needs perfectly, with any customisation you require. From interior shelving layouts, the size, the door type, and more, you have complete control. Many of these components are also replaceable, too, making it easy to keep on top of cold room refurbishment and maintenance, too!

Choosing the Right Walk-In Freezer
To ensure you choose the right walk-in commercial freezer for your needs, you need to consider the following:
- Application
- Do you need to keep already frozen stock frozen, or freeze products from fresh? If you are taking in fresh products to freeze, how quickly does this need to happen?
- Size
- The size of your unit should give enough room to store everything and be accessed comfortably, without wasting energy.
- Location
- Where you need it in the room, the floor it’s on, and if it is indoors or outdoors, will influence design and installation.
- Refrigeration system
- All-in-one units, like monoblocks, offer simple installation and plug-and-play usability, while remote systems may be better for larger or more demanding environments.
- Build quality
- Choosing trusted, experienced cold room design and install teams will ensure that your freezer cold room meets your needs and lasts for as long as possible when partnered with appropriate maintenance.
Being mindful of these specifications, among others, will mean that your investment is genuinely beneficial to your business and brings an excellent return on investment.

Frequently Asked Questions
Power consumption will depend on the size and usage of your industrial walk-in freezer. It typically uses around 15 – 40 kWh per day, while a standalone freezer might use around 1 – 3 kWh.
While their daily and annual power usage is higher, you can keep much larger quantities frozen with a much tighter control on the accuracy of the temperature, making it more efficient in the long run.
There may also be ways to use the energy more efficiently, including by increasing insulation, choosing the right kind of cold room door, and much more.
Contact MTCSS if you want to find ways to ensure your cold room is running as productively as possible.
Seeing frost in your walk-in freezer typically indicates that there is an air leak. This air leak could be caused by a range of things, such as:
- The age of your cold room
- Poor cold room door and frame set-up
- Your cold room door is being left open for too long
- Issues with your evaporator system
Ice build-up poses a risk in your cold rooms due to the health and safety risks associated with it; damaging your products and potentially getting personnel stuck in your walk-in freezers. So, it’s essential you get in touch with a maintenance team to correct the issue as soon as possible.
As a standard, walk-in freezers maintain negative temperatures between -1 and -40°C and this is recommended for the majority of walk-in freezer applications.
However, this is dependent on the products you store and the industry you are in, as many will need to adhere to more specific requirements.

Absolutely! It isn’t a requirement for you to have a business in order for you to invest in any temperature-controlled storage.
If you have an idea of where you’d like your walk-in freezer to be installed, how much room you have to build your walk-in freezer, and what you’re intending to store in there then our team can design a walk-in freezer that’s bespoke to you.
We would need to understand your exact requirements, and what you’re looking to achieve from your walk-in freezer to be able to offer you a price. This is because everyone has different requirements!
Your individual requirements will determine the additional components of your cold room, which is why it is hard to give an estimated figure for how much a walk-in freezer would cost.

Yes – walk-in freezers must have a floor to avoid frost heave, as well as making sure your walk-in freezer is optimally insulated for your products.
Frost heave describes the upwards swelling of moisture pockets on the floor of your walk-in freezer that contribute to an unsafe cold room because of unlevel or loose flooring.
If you have an issue with your floor, MTCSS is here to help – we can help you decide which type of cold room flooring would be most beneficial to your walk-in freezer.
The easiest way to keep your walk-in freezer maintained and in optimal working order is by cleaning it regularly and investing in regular cold room maintenance.
This maintenance will allow elements of your walk-in freezer to be replaced as needed, improving the efficiency and overall safety of your freezer cold room.
Investing in cold room maintenance also allows our team to intricately clean all elements of your cold room – including areas that would be neglected/easily missed by regular and routine cleaning schedules.
Cold room condition reports from MTCSS can help you identify the parts of your walk-in freezer that could benefit from cold room maintenance.
The main health and safety risks in your cold room can be eliminated by ensuring your walk-in freezer is maintained regularly and that any broken elements are replaced swiftly.
However, the most common risk associated with walk-in freezers is getting trapped inside and ice build-up (an excess of ice on the crucial parts of your cold room, such as around your cold room door). Usually, this occurs when your cold room door frame or handle is broken, preventing the cold room door from fully opening.
Due to the negative temperatures they maintain, getting stuck in a walk-in freezer (coupled with ice build-up) can become very dangerous very quickly, so be sure to keep an eye out for this as part of your daily checks.
