Commercial refrigeration equipment market to soar in the coming decade

peasThe propagation of our modern lifestyle is fuelling the demand for commercial refrigeration equipment. According to a new report by Grand View Research, Inc. this market could reach up to $46.4 billion globally by 2022.
It is actually the growing frozen food industry that is leading the growth of the commercial refrigeration market. Indeed, the frozen food market has been growing steadily for several decades now and is likely to keep on growing in the future. Several factors can explain this impressive growth and are detailed below: Continue reading

Magnetic refrigeration: the future of refrigeration


A new type of refrigerators could, in the coming years, replace the classic ones. Those new fridges that are far cheaper, quieter and more efficient work using a process called magnetic refrigeration. This technology has been known and experimented with for a long time but it can now be applied to domestic appliances and could even be used in various applications. Continue reading

The Impact of Fridge in our lives

Fridges might be a recent invention but refrigeration has been existing for centuries. Ancient civilisations in China for instance used blocks of ice harvested from frozen lakes to refresh their food or drinks. However, it’s only in 1913 that the first domestic refrigerator was invented. The invention then quickly became more commonly used, 99% of British households own a refrigerator and in the USA, up to a quarter of the population possesses two fridges. We therefore tend to take refrigeration for granted without realising the extent of the impact it had on our life. Continue reading

Maintaining your Refrigerator

Commercial Kitchen

In a commercial environment it is important for all equipment to be maintained appropriately as the cost of repairs and the effect a non-functioning piece of equipment can have on a business can be huge. If your refrigerator is properly maintained this will increase efficiency, reduce running costs and longevity of the unit.

It is important that you carry out some maintenance on your refrigeration unit, not only to keep it running but to ensure you are adhering to the Environmental Health Organisation’s regulations.
Here at G T Refrigeration we have put together some quick tips for you to ensure your units are kept up to a high standard.

It is important that you check your door seals regularly. This is because if they are split, cracked or not fitted correctly, this is the perfect breeding ground bacteria and it will also lead to loss of energy which isn’t efficient. Continue reading

Ever wondered how your refrigerator works?


Before refrigerators as we know them were invented they used to be a box that was topped up with ice regularly in order to keep food cool. At the beginning of the 20th century Frigidare launched their first electronic fridge for households. They had sold 200,000 models by 1926 and had to build a new factory in order for them to keep up with demand!

The bare bones of what a refrigerator does is push hot air outside the unit in order to keep the contents cool. The most common way of doing this is by tubes that are filled which a chemical liquid (refrigerant) which boils when the air pressure is reduced. Once it has boiled it turns into a vapour which then absorbs energy. This is the process that transfers energy from the inside of the fridge to the outside, therefore keeping the contents cold.

Refrigerator Magnets – More than just your average bric-a-brac

Fridge Magnet

Every so often, something weird and wonderful comes from the air conditioning and refrigeration world, hence the air conditioned suit. This week we have heard that now refrigerator magnets may be able to cool fridges!

Everyone loves a fridge magnet and it is predicted that in the future they will be so much more than clutter for the front of your fridge. According to MIT researchers they could be used as the cooling agent.

Their theory explains that the magnons that are found in magnets rotate and is called “spins” as well as these spins, the magnons also give off heat and according to the research that was carried out that when the magnons are introduced to a magnetic field, they travel from one end to another. This means that the heat is taken with them and therefore a cooling effect occurs. Continue reading

Should Refrigeration Units have Doors or Not?

Ice Cream Fridge

When you walk into a supermarket it is no surprise that the fridges, and sometimes the freezers, don’t have doors on them, yet at home you wouldn’t even dream of having the fridge door open constantly. Well this subject has been up for debate for the last three to four years because not only will having doors on refrigeration units reduce the supermarkets energy, it uses less energy and therefore they operate at a more environmentally friendly level.

There are many benefits to putting doors on refrigeration units including lowering the electricity bill, LED lighting can be used and enhance the look of the products and the aisles won’t be unnecessarily cold, providing a better experience for the customer too. Continue reading

White Christmas or More Weather Warnings?

We have probably all gotten our hopes up for a white Christmas this year. The early snow fall did indicate this is the way the weather was going to turn out. Well unfortunately we will just be subjected to even more rain (if this is possible!) Christmas is going to be a soggy one.

The weather warnings that have come as a result of heavy rainfall mean that the transatlantic mild fronts have been sent on their way and our chances or snow are dwindling.

In areas such as Cornwall and Devon there have been amber weather warnings. This mean anyone in this area needs to be prepared for potential flooding. When the time comes this means all furniture and white goods such as refrigeration units should be moved or protected. There has been a yellow weather warning issued in the Midlands for when this bad weather moves from Cornwall upwards. By Thursday, those in Yorkshire will also have a yellow weather warning.

Things aren’t going to improve over the weekend either, there is yet more rainfall pushing its way through the country. The Met Office has said this, “Very unsettled and windy, with occasionally heavy train pushing north-eastwards.

“Further locally heavy rain is likely midweek separated by drier showery interludes, with the best drier weather likely to be in the east. Strong to gale-force winds are also likely in places, but especially in the north-west. Temperatures will mostly near or perhaps a little above normal, although patchy overnight frost remains likely, a pattern that should continue in the run up to the New Year, with similarly unsettled conditions likely to prevail.”

Longer window without refrigeration for Meningitis vaccine

Regulatory authorities have announced that a new meningitis vaccine, MenAfiVac, can be stored without refrigeration for up to four days in what is being hailed as a significant breakthrough for Africa’s “Meningitis belt.”

Whilst such a short amount of time may seem trivial to some, one of the biggest obstacles in providing vaccination courses in Third World countries is keeping vaccines cold when transporting it from electrified cities to villages without power. Using antipolio drives as an example, the freezers, generators and fuel necessary to make ice for the shoulder bags of vaccinators is more costly than the actual vaccine.

Previous meningitis epidemics had cost countless lives in Africa, the hot hattman winds contributing to the deaths of 25,000 Africans and leaving 50,000 disabled during the worst years.

MenAfriVac, produced in India, was originally introduced in 2010 and in Chad this year, the vaccination campaign cut cases to near zero in the districts where it was used whereas other nearby districts suffered serious outbreaks.

Experts now say it is safe for four days, provided it stays below 104 degrees.

Though temperatures in Africa do exceed that, Dr Godwin Enwere, medical director for the Meningitis Vaccine Project, ensures teams will typically remove the vaccine from the coolers before sunrise and distribute the vaccine to villages before the afternoon hours when temperatures peak.
