Could not recommend more! I wanted an air conditioning unit installed in my home, and Not Just Cooling delivered excellent service every step of the way. They came out for a quote promptly, helped customize the unit and installation to suit my home, and had it installed just a few weeks later! I had several questions throughout the process, and they were always available and very knowledgeable. They were incredibly considerate during install (masks and social distancing of course) and consulted my opinion when appropriate. In and out in just a few hours and even ran the hoover before they left! Very happy to be in business with Max and Claire :)

After years of suffering with overheated legs I have Just had an aircon unit fitted in our bedroom, the installation went like a dream, the two fitters where brilliant, clean and tidy. What a massive difference it has made- no more overheating legs, a lovely controlled air temperature and a good nights sleep. The price was very competitive and would highly recommend, only wish I had it fitted sooner.

Cannot recommend highly enough, repaired my wine cooler next day and really got me out of a pickle. Lee was great to deal with and service was excellent, so much so I've asked them to install me some air con!

First class service, certainly use them again.

Fantastic company who installed a whole heating system in our offices. Great team and great communication. Would highly recommend!

Ultra-Low Temperature Refrigeration

If you have a cold room or you are using ultra-low refrigeration in a commercial business, a medical or a scientific laboratory you’ll need reliable and affordable appliances.

Ultra-low refrigeration can be achieved by using a cascade system. A cascade refrigeration system has several cycles which are layered above each other forming a cascade. It is a two-stage process which uses two types of refrigerant which pass through a high and then a low stage. It is this system which enables the appliance to obtain temperatures from -50° down to -120°.

It’s unlike a traditional fridge where there is one refrigeration cycle. The temperature here is also cooled with the help of the refrigerant and the compressor. But, without the cascade system the appliance doesn’t give you ultra-low temperatures.

The benefits of cascade refrigeration include:

Lower Running Costs – This is due to the fact that the system uses less energy per ton of refrigeration. It also means that part loads are also energy efficient, unlike traditional refrigeration which works better when fully loaded.

Environmentally Friendly – The refrigerant used in many cascade systems are low ozone depleting liquids which are non-toxic.

Low Maintenance – Cascade refrigeration isn’t difficult to install, it’s powerful, reliable and its low maintenance.  

Here at Not Just Cooling we work closely with commercial businesses, hospitals, laboratories and universities to provide cooling solutions that keep your products at the ultra-low temperatures required. We can provide appliances that fit into small or large spaces or we can give you a tailor-made option.

We specialise in the installation, service and repair of cascade refrigeration systems using trusted manufacturers of high quality products. If you would like to know more about our ultra-low refrigeration offerings by contacting us or by giving us a call on 0115 971 7518.
