Maintaining Your Standards


CellarBreeze™ utilises the UK’s weather system to save you money on running your cellar cooling system.

If the outdoor temperature is at least 2 degrees colder than your required cellar temperature, CellarBreeze™ will take over from your current Cellar Cooling System. It maintains the correct cellar temperature, without the need for the refrigeration system to be in continuous operation. The system is totally automated and will switch off your cooling equipment if the internal temperature can be maintained from the air outside.  This combined with SwitchBox and EndoCube is the most energy efficient way of cooling the cellar and… Continue reading

Switchbox™ / Switchbox Pro™

Switchbox™ has primarily been designed for Cellar Coolers and Remote Coolers although it can be used on Cold and Freezer Rooms.

Switchbox™ saves you money by switching the cooling system off automatically between midnight and 06:00. These times can be modified to suite different activities and if you have preferential night time electricity rates.  During these times, trade has usually ceased and the rooms are usually shut up with the lights off.  Central heating systems are usually off and other heat sources are shut down.  Ambient temperatures are naturally cooling and the product temperatures will actually maintain… Continue reading


EndoCube has been designed primarily to reduce the running costs on large refrigeration equipment such as cellar coolers, cold rooms, freezer rooms, large upright fridges and freezers.

All refrigeration equipment works in the same way. It is usually controlled by a thermostat that reads the air temperature within the unit. When the temperature rises above a defined threshold a cooling cycle is activated.

It is at the start and during the cooling cycle when most energy is used.  To reduce the amount of energy used, we need to reduce the number of times a cooling cycle is activated, and… Continue reading

Introducing PRO-Tect™

For quite some time now the STSUK Team have been working on a service that will benefit both customers and our engineers alike. Lots of ideas were bounded around, some kept and some were discarded. And now we are ready to fully launch

STSUK are proud to announce PRO-Tect™. It is a membership scheme which we feel is a little like the RAC/AA. One of the biggest gripes customers have, is having to pay for call outs and one of our biggest headaches is travel time.  We think that PRO-Tect™ is the answer to all of our prayers!… Continue reading

Do you know … Refrigeration Cleaning Chemicals?

Whilst going through some photos from some of our jobs  a few weeks ago I came across this image of an outdoor condenser on a cellar cooler

It shows that the fins have totally corroded away. I asked the team what had happened. Basically the aluminium fins on condensers are exposed to all kinds of conditions. In some areas they are also subject to corrosions from substances which become airborne such as salt from gritting roads and sea salt in coastal areas.

Another issue is that unfortunately some cleaners are acid based and after just six treatments can take… Continue reading

How STSUK helped a Pub save £95 per month.

We had a call from one of our clients, asking us to come out as their cellar was too warm.  When we arrived on site we found out that the mechanical thermostat had failed.  In this situation, SwitchBox Pro™ was the obvious choice, as the cost to replace the thermostat alone was almost the same as the upgrade.  In addition, we added EndoCube which reduces the number of compressor starts. This puts less strain on the compressor as well as reducing energy costs.

SwitchBox Pro™ is a product we have designed to reduce the running costs of… Continue reading

Are you leaking away money?

Anyone who is connected to the refrigeration / air conditioning industry will have noticed the huge increase in the costs of refrigerant over the last few months. For example, since January this year the cost of R404a has increased by a massive 40-50% each month!!

But this information is not feeding down to the end users and you are the ones that the increase will ultimately affect.

Why are refrigerant prices going up?

We all know that there is a global need to reduce the emissions of greenhouses gases.  There is now a focus on refrigerant leaks because some… Continue reading

The Importance of Cellar Cooling Maintenance

If you have a pub, restaurant hotel or similar kind of business, you will know how important it is to serve cool drinks. In order to do this, you need a reliable cellar cooling system. Regular Cellar Cooling Maintenance is imperative to ensure that your system doesn’t break down on days when you need it the most.

Our Cellar Cooling Maintenance checklist makes sure that our fully trained engineers check every inch of your equipment for any potential issues before they happen.

Most cellar coolers are also affected by F-Gas regulations which is a legal requirement. The legal responsibilities fall… Continue reading

Do you know ….. Air Conditioning isn’t just for Summer?

One comment we hear all the time is ……. Air Conditioning? Oh yeah that’s for cooling right” or what’s the point for the typical British Summer of two hot weeks a year? Whilst there is some truth in the statement, it is common myth that Air Conditioning is only good for cooling spaces in those few precious weeks of summer that we might get each year. What most people don’t realise is that AC is an absolutely brilliant form of heating especially in domestic homes.

Unlike conventional home heating systems, air conditioning can be set to warm just one or… Continue reading

How STSUK helped an IT company keep their cool

Pro-Networks are a leader IT support provider based in Chester. They know the importance of keeping their staff and their equipment cool. When it was time to change their Air Conditioning Maintenance provider they contacted STS UK.

We visited site and met with MD Paul Crudge and General Manager Tom Jones. We discussed all of their requirements before putting together some quotes based on their needs..

Both gentleman had concerns over thoroughness.  Despite numerous visits over the last few months, two of their systems were not working correctly.  We secured their work on a 12 month contract.

We… Continue reading

Following an initial discussion with Pierre about the maintenance and repairs of our air conditioning installation, we felt confident enough to hand over the onboarding and servicing schedules to STSUK. The initial onboarding was carried out quickly and operationally acceptable as the engineers worked in a manner which reduced inconvenience to our office-based staff. Full reports were offered for our Health and Safety files and a number of faults discovered which involved having to replace two units. In order to reduce inconvenience I asked for an early start to the works and the engineers arrived at 7am as agreed each day! All of the works were carried out in accordance with their quotation and all units are working perfectly. The engineers worked with respect for the delicate equipment around them in the server room and protected the surrounding areas from dust whilst drilling. I wouldn’t hesitate to recommend STSUK if you are seeking expert and reliable service.
