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.

Dealing with humidity in factories: ventilate or heat?

Posted by Paul Langford on 20/09/16 12:00

Steam and humidity are by-products of many industrial production processes. But they can have an extremely negative effect on working conditions.

When is natural ventilation the right solution for power plants?

Posted by Paul Langford on 16/08/16 12:00

The quick answer is: in most cases. Power plants generate large amounts of internal heat and tend to be in tall buildings, which present ideal conditions for natural ventilation to work at its most efficient.

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 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.

Does your business comply with ESOS? Don’t leave it too late!

Posted by Paul Langford on 25/09/15 09:00

Are you a UK business with more than 250 employees? Does your business generate at least £40 million in annual turnover and have a balance sheet of more than £34 million? If the answer is yes to either question, you are required to complete an energy efficiency audit by 5 December to comply with the government’s Energy Saving Opportunity Scheme (ESOS). Should you fail to comply, you risk a fine of up to £50,000.

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.

Why natural ventilation is best for power generation facilities: The facts and figures

Posted by Graeme Clark on 29/07/14 11:30

In my opinion, a natural ventilation system should always be the first choice for power plants, energy from waste, biomass, hydro stations, transformer stations and other similar buildings for 2 reasons:

1) The Environment 

The number and frequency of extreme weather events has been on the increase throughout the world. The climate is changing, of that there is no doubt, and the most popular theory is that this is due to the rise in CO2 emissions.

What to do when you have a condensation problem

Posted by Paul Langford on 08/04/14 11:30

Condensation forms when humidity is so high that the air is saturated and can’t take on any more moisture. The solution to the problem is not complicated, but you need to be sure you are measuring the right variables to identify the best method to resolve it.

When does condensation become a problem?

How to deal with engine exhaust emissions when local exhaust ventilation is not an option

Posted by Paul Langford on 04/03/14 11:30

Controlling diesel engine exhaust emissions in enclosed spaces such as maintenance workshops is easily done with local exhaust ventilation (LEV), which can be as simple as fitting pipes to the vehicles’ exhausts while they are being serviced in order to draw the fumes outside. However, there are situations where this is not an option, for example in a warehouse where there is heavy vehicle movement inside the building, as vans and lorries come in and out for loading and unloading.

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.

What is evaporative cooling? Read our White Paper to learn the facts

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

The benefits of evaporative cooling in warehouses and industrial buildings are many: it is a highly energy efficient technology, that uses no refrigerants, provides a pleasant indoor climate, is simple and easy to maintain and, last but not least, running costs are four to seven times lower than traditional air conditioning solutions – and they are even lower in data centres.
