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.

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.
To find out more about configuring your walk-in freezer to a suitable temperature range for your business, contact the MTCSS team to discuss this further!
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.

The short answer to this question is yes.
Walk-in freezers must have a floor in order to avoid frost heave (the upwards swelling of moisture pockets on the floor of your walk-in freezer that contribute to an unsafe cold room), was well as making sure your walk-in freezer is optimally insulated for your products.
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 investing in regular cold room maintenance.
Cold room maintenance will allow elements of your walk-in freezer to be replaced and cleaned, therefore improving the efficiency and overall safety of your freezer cold room.
Investing in cold room maintenance allows our team to intricately clean all elements of your cold room – including areas that would be neglected/easily missed.
Cold room condition reports from MTCSS can help you identify the parts of your walk-in freezer that could benefit from cold room maintenance. Learn about them here
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. Read our article for more information
Bert De Mooij, Bespoke Chiller Cold Room for Q Flowers Ltd 2021
From coming into contact with MTCSS to the finished product, has been a great and easy process.
The members of the team listened to our wishes and offered us exactly what we needed. From picking the type of cooler machines, the doors, the lights - everything was exactly adjusted to our wishes.
Even though through the COVID period where availability of materials were challenging, the cold room was finished on the date as was planned when signing for the order.
Very professional company from start to finish.
Catherine Hester Fenwick, Ambient storage at Brabourne Wines 2021
‘Brabourne Wine is a small, family run vineyard in Kent. In an Area of Outstanding Natural Beauty, a Conservation Area and with listed buildings, we needed to find a solution to store our wine without building afresh or making any material differences to the current buildings. MTCSS were amazingly flexible. They worked with us to develop a solution that fitted inside one of our outbuildings. Given the limitations on space and the requirement to have racking suitable for pallets, virtually everything about the project had to be bespoke but Darren never lost patience with the endless queries in the planning phase. Once on site, the team was professional, friendly, flexible and quick. They have delivered a solution which is perfect for our needs and exceeds our expectations. We are at the smaller end of their usual customer base, but we were never made to feel as though we were any less important than a major supermarket chain. We would certainly recommend them to anybody needing a controlled climate for storage (or any other reason)’

Dual Compartment Cold Room Installation, London
From the beginning I found Gem’s customer service fantastic, out of all of the companies we spoke to for quotes she was the most responsive and attentive. Even when we were still finalising and it wasn’t confirmed if we were proceeding with MTCSS yet, she was always great with keeping in contact to see if we needed anything, and very responsive with emails, and also phone calls.
Andy and Nathan, have been great throughout the entire process. Both have been on hand for any queries we have had and very responsive again to all forms of communication. Everything has been handled promptly and efficiently both before, during and after the build. Any questions we have had they have always gotten back to us with an answer very quickly.
The gentlemen who completed the install here on site, where very friendly and mindful of business operations while completing work. Each day they would check in with who was here in the morning to explain what they would be doing, what access they required, and asked if and how this might affect our operations or customers. Again, they were very clear and open with communication and was happy to help find solutions when we had issues with the shelving.
Overall our experience with you has been very good and we have been left a happy customer. I would also just like to say a thank you to yourself Gem, Nathan and Andy as you have all been very great throughout our customer journey!
