Is evaporative cooling safe?

Posted by Paul Langford on 17/01/17 13:00

The first question that comes up when discussing a water based cooling system, such as evaporative cooling, is always about its safety and in particular about the control of legionella bacteria. In this article we will explain what you should be looking at if you are considering such a system, illustrating with examples of our approach to ensuring that our evaporative cooling systems are safe.

Controlling temperatures in food production

Posted by Paul Langford on 19/07/16 12:00

Various food and beverage sectors have different climate control requirements, depending on the processes being carried out. However, they all share an overriding concern for overheating and hygiene in order to protect their goods and ensure quality.

How to improve productivity when the temperature rises

Posted by Paul Langford on 14/06/16 12:02

This Colt advert first featured in the Financial Times
almost 40 years ago, and still rings true today!

As the temperature rises during the summer months, it is important to asses your productivity levels. If your factory is too hot, then you will almost certainly suffer losses in production, as well as a whole host of other issues.

However, there is a solution.

How to select the correct air filters for your HVAC system

Posted by Laurence Cockman on 07/06/16 12:22

Air filters are used in heating, ventilating and air conditioning (HVAC) systems to improve air quality in indoor working environments. They can also serve to protect the HVAC equipment.

Pollutants can originate from a source outside or inside the building. In this blog I will discuss pollutants which originate outside of the building.

Feeling the heat? Upgrade your existing ventilation system!

Posted by Andrew Wright on 17/05/16 12:00

As a factory manager, you may find that in spite of keeping your mechanical ventilation system in perfect condition, the temperature in your plant is increasing. Over the years, the use of your building may have changed, as with the introduction of lean manufacturing practices, there may be a higher density of production machinery with consequent higher heat load in some areas of your facility. This means that the mechanical ventilation system as it was originally designed and installed no longer meets your requirements.

Are you missing out on the savings that come with evaporative cooling?

Posted by Paul Langford on 23/02/16 12:00

Evaporative cooling is an exceptionally efficient and economical means of cooling industrial buildings, production facilities, warehouses and data centres. It is not a new technology, infact it is widely used around the world. So why isn’t it more widespread in the UK?

Common misconceptions about this excellent technology are stopping many facilities managers and factory owners from taking advantage of the considerable savings it can achieve for them. Let’s address these concerns and look at the main benefits of evaporative cooling.

A solution to overheating in common corridors of high rise buildings

Posted by Paul Compton on 08/09/15 11:30

In this blog we don’t usually write about our products, but we have recently worked on a project that we think will provide interesting insights about preventing overheating in the common corridors of taller apartment buildings.

A cooling system that generates energy: Yes it's possible!

Posted by Paul Compton on 21/04/15 11:30

Today’s blog article is a bit different from our usual contributions: we were recently involved in an unusual project with a client who thinks very much out of the box, which resulted in an ingenious solution that we thought could be interesting for you.

Choosing a cooling solution for a factory: Total Cost of Ownership

Posted by Paul Langford on 24/03/15 11:30

When choosing a cooling solution for a factory, it is important not to focus only on the initial investment, but to consider all the elements that make up the total cost of ownership (TCO) of the system.

What’s stopping you using evaporative cooling?

Posted by Paul Compton on 18/11/14 11:30

An American colleague recently described evaporative cooling as “swamp technology”, a quaint term which, according to Wikipedia, was coined as a reaction to the odour of algae in early units.

This got us thinking about whether there were any other issues or myths that put people off the technology. In this country we’re blessed with a temperate climate so for many applications and for much of the year the cost and complexity of a full air conditioning system is not necessary and a simple, low cost evaporative cooling system may be a better solution.

Overheating in corridors: when natural ventilation is not enough, evaporative cooling comes to the rescue

Posted by Paul Compton on 08/07/14 11:30

In previous articles we wrote about how you can solve overheating in residential buildings’ common areas by using the smoke control system to provide simple and effective cross flow ventilation and extract warm, stale air from these spaces. However, there are cases when this won’t be enough and the system will need some help to lower the temperatures to the desired level.

Why coffee roasting houses need both cooling and ventilation

Posted by Paul Langford on 04/02/14 11:30

Who doesn’t love the smell of freshly roasted coffee? But there can be too much of a good thing, and coffee roasting facilities have more to worry about than an excess of fragrance: they have to cope with the high levels of heat generated, which becomes even more of an issue during the summer months, as well as the build-up of carbon monoxide concentrations in the 72 hours following the roasting process. Efficient ventilation to extract the excess heat and carbon monoxide is essential.

Questions and answers from our 'Evaporative cooling for data centres' webinar

Posted by Laurence Cockman on 28/01/14 11:30

At our recent CPD accredited evaporative cooling webinar, I received some interesting questions in the Q&A session at the end. I would like to share my answers, which have been edited to make them clearer.

Q: How do you deal with freezing conditions?

A: During colder periods, where freezing outside conditions would be expected, the evaporative coolers would not be used, and they would have been earlier drained down and isolated as part of a winterisation process. This means that there is no chance of any water freezing inside the unit, as it contains no water.

Freezing conditions are then dealt with by carefully mixing quantities of that cooler outside air with warmer waste air from the IT equipment, therefore providing air at desirable conditions.

Economical, environmental, safe: you can have it all in your data centre with evaporative cooling!

Posted by Laurence Cockman on 10/12/13 11:30

Data centres are thirsty for electricity, most of it used for maintaining temperature and humidity within the maximum and minimum levels that the servers need to operate properly. This also means that data centres tend to have a big carbon footprint. However, it need not be so: evaporative cooling provides a very cost effective and energy efficient solution to the problem. And, even though it is a water-based system, there are no health risks when it is designed correctly.
