The question of walk-in freezer eco-friendliness is common. We get asked about how eco-friendly our freezer rooms are all of the time, and for good reason – like ourselves, businesses don’t want to increase their impact on the environment if they can help it.
With regard to freezer room eco-friendliness, the 2 most important things to consider are:
- 1)The amount of power the freezer requires to operate, and;
- 2)What type of refrigerant the freezer uses.
So let’s take a look at these.
The amount of energy a walk-in freezer uses is measured in watts and kilowatts (1 kilowatt = 1000 watts). The annual power consumption of a walk-in freezer, if it were to be plugged in 24 hours a day, 365 days a year, would be around 700 kWh. One kWh is referred to as 1 unit of electricity, so a walk-in freezer can be expected to use 700 units of electricity annually.
To put that into perspective, your average fridge freezer with an A++ energy rating uses somewhere in the region of 206 kWh every year. When you take that into account, walk-in freezers are actually relatively energy efficient given their size.
Additionally, our walk-in freezers are built to the highest quality. Quite simply, they are designed to be as efficient as possible, trapping cool air so that it cannot escape. All freezers are designed this way but ours are built up panel by panel to ensure maximum efficiency – this also carries the benefit of our walk-in freezers being able to fit practically anywhere.
Older freezers used a horrible, ozone-depleting refrigerant called Freon R-12. Many appliances using this chlorofluorocarbon are now banned from sale. Modern freezers, including our own walk-in freezers, use either a gas called R-600a, or isobutene, or a gas called HFC-134a, or 1,1,1,2-Tetrafluoroethane to cool the air. These two refrigerants have been scientifically proven to not deplete or adversely affect the ozone layer.
This is, in our opinion, the most important fact about our walk-in freezers. The refrigerants used in our freezers simply do not affect the ozone layer like chlorofluorocarbons (CFCs) do, so you can rest assured that any freezer unit you hire from us is environmentally-friendly.
Transport of the freezer
When questioning the eco-friendliness of walk-in freezers, it’s also important to consider that such a system will be delivered by trailer. However, it’s also important for us to point out that the initial transport of the walk-in freezer contributes wholly to the emissions generated by our walk-in freezer hire solutions. And because we are ideally located to serve businesses in London, Berkshire and most of England and Wales, journey times are short and our drivers will, whenever possible, avoid congestion to minimise emissions generated.
Lastly, we would point out that whilst walk-in freezers are becoming a more popular choice for long-term internal cold storage, freezer trailers and fridge trailers are actually a more sensible choice for short duration, external requirements. So if you are currently considering a freezer trailer or a walk-in freezer, you can rest assured that our mobile and portable refrigeration units are as eco-friendly as possible.
