For a century, scientists had known that you could make it [a packing ship] artificially colder by compressing some gases into liquids, then letting the liquid absorb heat as it evaporated again.
But commercially successful applications remained elusive. Every day food such as banana’s became a delicacy as the overseas transportation of the fruit proved unsuccessful with the journey exceeding the shelf life.
Argentina’s government even offered a prize to anyone who could keep its beef cold enough for long enough to export it overseas!

The Department of Environment Food & Rural Affairs plan to introduce penalties from April next year in England and Scotland for companies and individuals who breach F-gas regulations.
“A maximum fine of £50,000 could be applied to breaches including failing to correctly label F-gases or products containing them; failing to comply with the requirements for declarations of conformity for importing products containing F-gases; and failing to keep records of F-gases used in equipment or F-gas sales.”

Following 3 fatalities caused by ammonia, British Columbia MP has called on the Canadian Government to begin phasing out the fatal gas.
Commonly used in refrigeration systems, Stetski told the House that there had been over 50 ammonia leaks in Canada since 2007, “many resulting in injuries and deaths”.
Maintaining that CO2 systems offer a safer and more efficient alternative, Stetski said: “I call on the federal government to work with the provinces to help municipalities phase out of ammonia based systems to ensure there are no more tragedies like the one suffered by the people of Fernie.”

Glycol fulfils an essential requirement to ensure the ultimate performance and the reduction of added maintenance costs of your cooling system. As part of a new email series, we’ll be sharing key information about the importance of maintaining a balanced fluid system within cooling or heating plant, allowing you to select the most suitable solution for your system.
Today, we’re dealing with glycol in cooling systems, and in our follow-up emails we will be sharing more information about glycol for heating applications and anti-corrosion, before finally revealing more details about our exclusive glycol solution.
Why is a glycol solution used in cooling systems?
In your system, a heat exchanger allows the transfer of heat between the liquid coolant (often water) and the refrigerant liquid. This refrigerant’s temperature is usually 6-7°C lower than the water temperature, allowing heat to flow and the liquid refrigerant to evaporate. If the refrigerant liquid is below 0°C or your water temperature below 6°C, it puts the water at danger of freezing, obstructing the evaporator and preventing coolant flow. This can cause permanent, irreversible damage.
The surrounding ambient temperature also plays a part here – even if your water temperature is high enough for the refrigerant liquid not to be anywhere near 0°C, if the ambient temperature drops below 0°C you run the same risk of freezing and irreversible damage.
Glycol is used in Heat Transfer Fluids (inhibited anti-freeze), and is suitable for multi-metal closed chilled water systems. Adding glycol to your coolant reduces the freezing point of the water, allowing the water to be efficiently cooled whilst also preventing any risk or damage to your chiller.
“Left to themselves things tend to go from bad to worse”.
Honestly, would you run your car brake pads to the point that damage is inevitable … metal squeals on metal? No! of course you would not, why? Because you value your car, scheduling it in for a service is now just a matter of course.
Love and attention is what we all require and mechanical refrigeration equipment is no different, in order to reduce the likelihood of equipment failure. Giving early warning by identifying a potential issue which can be scheduled for rectification thus reducing unplanned downtime.
Then adopt the same reasoning to your extremely valuable equipment which is essential in ensuring your business is successful.

The microbrewery industry is undoubtedly a growing industry, with many individuals taking their home brewing to a new level. Certainly there are over 1100 breweries of varying sizes in existence in the UK today. As more and more individuals are looking to set up their own microbrewery facilities, they’re also looking to find the most effective and efficient solutions for chilling and processing their beer.
If you’re operating a microbrewery yourself, you’ll appreciate how important it is to have facilities that have the ability to chill quickly and accurately but also to meet all necessary environmental legislation’s, plus adhering to any health and safety standards too.
With microbreweries, several factors need to be considered when choosing chiller equipment. First of all, it needs to be effective; it needs to be as economical as possible. Secondly you’ll need it to be reliable, and if it isn’t robust enough, there’s a high chance of failure when it comes to processing your brew. Equally you’ll want to choose equipment that can be maintained with ease. It goes without saying that it needs to be cost-effective too.
Perhaps you’re looking to only brew a small amount of barrels or maybe much more than this. Either way, you need to be confident that you’re choosing the right supplier to meet the individual needs of your microbrewery.
Certainly the clue to the ideal brew is down to the right temperature control, so it makes sound sense to get the right equipment in-house first. When it comes to chiller facilities, a glycol chiller will undoubtedly give you the capability to brew the high quality result that you’re aiming to achieve.
With such a specialist industry involved, it’s vital that you find a supplier who will understand the specific needs within the industry and be able to advise on the best chiller to suit. Securing the right temperature for chillers is absolutely critical for microbreweries, and also that they have the ability to provide maintenance as and when you need it; avoiding any delay which could be potentially disastrous to your brewery. Gone are the days of relying on banks of ice as this has the potential to delay brewing by many days. Have a look at the experience that Tiny Rebel Brewery found by installing GalxC chillers within their microbrewery.

Our latest is one of our most exciting to date, and is something new for the team here at GalxC. We were appointed as the supplier of a bespoke water cooling system for a project run by a large utility company.
The aim of the project was to ensure the provision of high quality drinking water to a large UK city.
The project called for 1.5Mw of cooling, with no power supplies readily at hand. The site in question was situated next to a large reservoir within a conservation woodland area. Therefore, there was emphasis placed on avoiding any kind of pollution or disruption to local wildlife.

When you’re running a business that relies on chiller equipment, considering the environment probably isn’t high on your list of priorities. However, you’ll recognise the importance of keeping up with legislation. With the demand for keeping your business green, you’ll probably be fully aware of the importance of reducing greenhouse gas emissions in order to protect the environment.
We know that the Montreal Protocol has meant that in replacing CFCs, HFC usage has certainly reduced emissions necessary for climate change. The use of ozone-depleting substances has been pretty much ruled out. Worldwide, 197 countries have signed up to the Montreal Protocol; which has led to a positive effect both on the global market and reducing CO2 emissions.
With a greater increase of HFCs in the environment, this now means that an alternative challenge now arises. It’s now recognised that unless the HFC emissions are not controlled, this could actually negate all of the entire climate benefits that the Montreal Protocol has worked tirelessly to achieve.
There are definite alternatives to HFCs, and certainly in not continuing with HFCs, it’s anticipated that by the year 2100, a 0.5˚C of global warming can actually be prevented through a phase-down process. Not to mention a cost-effective and practical alternative which will limit global average temperatures rising 2˚C to pre-industrial average temperatures.
On the legal side, environmental law and regulations are being continually tightened so it makes sound sense to consider alternatives to HFCs in your chillers. There are three mainstream alternative refrigerants to HFCs that remain safe for the environment. You could consider choosing ammonia or CO2alternatives. Both have performance-related and environmental advantages but also present drawbacks too.
On the other hand though, Hydrocarbon R290 refrigerant gives you the alternative solution that’s perfectly safe for the environment, cost-efficient and highly effective. Hydrocarbons perform as well as, and often better than those of HFC refrigerants, which makes them an ideal alternative.
