Top Tips for Enclosure Cooling

Rittal
It’s safe to say that there is a great deal of uncertainty at the moment; something which is being felt not just in the UK but in many countries across the world.

In these circumstances, the best thing that businesses can do is protect their existing assets. It’s fundamentally important to ensure that all assets perform at an optimum level during their entire service life, and for an organisation to continue its journey towards increased efficiency and reliability so that it can remain competitive in a changing marketplace.

In the industrial space, a company’s lifeblood is its machinery and all machinery has critical components such as its a.c inverters, motors etc. without which a very expensive robotic arm is just an elaborate statue, collecting dust. So it’s important that electrical equipment is housed within a protective environment, to ensure it operates to its full potential. 

A protective environment takes the form of both high quality enclosures and correctly prescribed climate control equipment. The two items work together to safeguard your equipment from the following:

High Temperatures Impact the Lifespan of Equipment

Prolonged high internal temperatures reduce the lifespan of your equipment. This will mean an increased chance of unplanned breakdowns, increased costs and reduced production output.

Furthermore, your equipment cannot work at 100% output once its maximum operating temperature has been exceeded, which means you will experience an overall reduction in your machine’s efficiency and reduced manufacturing output.

To prevent high temperatures being reached within the enclosure, correctly sized enclosure cooling products should be installed. This could be fans and filters, cooling units or air-to-water heat exchangers, dependant on both the amount of heat produced by the electrical equipment and the ambient temperature in the surrounding environment.

Low Temperatures Can Also Damage Equipment

Equipment needs protecting from low temperatures as much as high ones. In winter, when ambient temperatures drop, any equipment that has been idle over the weekend can be damaged as soon as it’s turned on from cold.

In addition, motors or compressors can experience problems when oil contained within sealed systems begins to increase in viscosity. This can damage the seals/components, again causing failures.

To prevent this happening, you should fit a correctly sized enclosure heater inside the enclosure. When connected to a thermostat, the heater will maintain an acceptable minimum temperature preventing any damage to electrical equipment caused when the low temperature minimum is exceeded.

Condensate Poses Safety Risk

Condensate can be a real issue when it forms within the enclosure and on critical equipment in high humidity environments. Condensate poses a real safety risk to the electrical devices and can cause catastrophic failure if left unchecked.

You can combat this problem by using a high quality industrial enclosure with a minimum of an IP54 seal to prevent humid air from constantly entering the enclosure. This can be combined with a cooling unit featuring an integrated condensate evaporator; the cooling unit acts as a de-humidifier and removes excess condensate from the pocket of air within the sealed enclosure.

Dust, Dirt and Corrosive Substances

Many industries suffer from dusty or dirty environments, which can impact on electrical equipment and its optimum performance. For example:

  1. Carbon dust in the steel or manufacturing industry
  2. Yeast or vinegar extract in the food and beverage industry
  3. Salt water vapour in the air in a marine or coastal application

The above contaminants will attack the wires and electrical connections within your enclosure. In time, this can corrode or (worse) short connections, which in turn can cause excess heat and/or a panel fire.

In highly contaminated environments, the best advice is to use a cooling product which does not allow dirty ambient air to constantly enter the enclosure, so fans and filters are a no-no. Air-to-air or air-to-water heat exchangers and cooling units are best solutions, dependant on the heat load as they will only treat the small pocket of air within the enclosure, but they will also reduce the level of contaminants entering the space.

Cooling Top Tips

Any change or upheaval that impacts on a company’s trading environment brings with it challenges, but also opportunities. The trick is always to optimise your business for success, reducing costs wherever possible, while maximising productivity and efficiency.

The long term benefits of maintaining a protective environment and allowing your equipment to perform to its optimum will, in turn, help your business to flourish.

Maintain Your Cool – Autumn is Here! … Time to Reflect

Rittal

Finally! The temperature seems to be reducing to a more bearable level, the nights are slowly drawing in and… do I see a hint of colour change in the trees?

That’s right Autumn is upon us once again and that can only mean one thing… It’s time to stop, look back at the summer period and understand how things went…

Four seasons campaign – Autumn October

Did You See –

  1. Electrical equipment under stress?
  2. Unexpected breakdowns?
  3. Emergency repairs needed on critical equipment?

If any of this sounds familiar or has happened to you, now is the perfect time to put plans into place to make your life easier when next summer hits.

Protecting Your Electrical Equipment

Servicing, upgrading or even specifying some brand-new Climate Control to protect your equipment is one of the most effective ways of creating a protective environment for your sensitive electrical equipment within your enclosures and ensuring it lasts for many summers to come.

Even if your cooling equipment is up to date, there is always an opportunity to make small improvements which will increase your overall efficiency. 

Implementation of Industry 4.0 Principles

A great example is the implementation of Industry 4.0 principles, simply put this is taking any data generated by cooling equipment and allowing it to be directly reported into your building management systems or straight to the relevant person in charge of managing the health of your electrical equipment.

This reduces the need for daily walk round with a clipboard, making notes of any issues. This old-style approach can result in things being missed and breakdowns occurring unexpectedly, however, with the solutions available you can choose to have e-mails sent directly to key personnel whenever limits have been reached and warning flags are showing. This means staff are more efficient and know they will be notified if any issues begin to arise. 

We know that your sole focus doesn’t lie on Climate Control. You have more important things to worry about, mainly keeping your business up and running and producing for your customers.

Helping You Get The Most Out of Your Equipment

That is where Rittal and LC Automation can help. Over the next three months we are going to cover a different theme related to Climate Control but with the focus on how you can utilise this information to get the most out of your equipment, by creating that protective environment and allowing it to thrive and stay healthy.

This takes the workload off you when the temperature starts to rise again and allows you to concentrate on more important matters while knowing you have implemented systems to keep your equipment chugging along.

Energy Efficient and Cost Effective

The additional benefits of undertaking this action is the reduction in energy usage and costs related to the replacement of spare parts etc. If items are tripping out every year, this causes a high level of wear on components which can result in more order being produced to replace burnt out cards etc.. All of these small changes are going to impact your bottom line and overall efficiency.

The Next Three Months Topics Are Going to be as Follows;

  1. Service & Maintenance of Cooling Equipment
  2. The Fundamentals of Cooling
  3. Focus on: Cooling Industry

If you are interested in any of the topics mentioned, look out for the latest Rittal Climate articles in the LC Automation email News Update.

In the meantime, if you have any specific questions or would like more information about Climate Control or Rittal Enclosures, give LC Automation a call on 01254 685900. They will be happy to help.

What Does the Future hold for Food & Beverage Manufacturing?

Rittal

Food and beverage manufacturers of all sizes are facing huge operational challenges right now.  Sudden increases in consumer demand, shifting expectations, changes in food safety legislation, and emerging technologies, all require companies to be responsive, agile and flexible.  There is also the matter of ensuring seamless production continuity, to ensure consumer confidence around maintaining food and beverage supplies.

As digital technologies continue to transform global markets, no industry remains untouched, and food and beverage manufacturing is certainly no exception. 

Let’s consider how each of these three factors can impact day-to-day operations on the production floor, and how leading manufacturers are adapting to win.  

Standards and Legislation

In recent years, food and beverage manufacturing regulations have changed significantly across the globe due to technological and scientific advancements. Europe has long been at the forefront of these legislative changes and successful companies will likely be those who stay ahead of the curve by implementing changes sooner rather than later. These companies will avoid both production downtime, and the potential for higher costs associated with refits, when new legislation eventually passes.   

Even in our current outcomes-based regulatory framework, reducing cleaning time and ensuring impeccable hygiene standards continue to be key areas of focus. As the physical landscape of manufacturing shifts to accommodate the increased presence of technology, so too will our approaches to safety and cleanliness. 

This leads us to our next topic: the presence and proliferation of technology in food production spaces.  

Food Sustainability and Corporate Responsibility

There’s no denying that we all have a responsibility to implement sustainable environmental practices. But from a commercial perspective, it’s also worth your time to embrace sustainability as millennials and Gen Z begin to dominate the consumer market. 

The consumers of the future will place huge value on environmental sustainability, and they’ll also go out of their way to support companies who follow environmentally friendly practices. 

Manufacturers that want to reach this audience will need to implement changes that reflect this shift in consumer priorities and effectively communicate the changes that have been made. To do this, you’ll need to streamline every aspect of your business with a new focus on environmental sustainability. 

Whether it’s recycling production materials to close the loop on waste outputs, or reducing the energy consumed during cleaning, every part of your process should be moving towards a more sustainable future, either directly or indirectly.  For example, Rittal’s HD enclosures are specifically designed to make them quicker and easier to clean.  HD enclosures are typically power washed, so reducing the time it takes to clean them will lower both water and energy usage.

In order to offset the cost increases associated with making these transitions, industry leaders are continuing to refine efficiency-boosting practices like CIP to make production facilities greener.

Technology and Digital Transformation

At this point, we can consider the massive impact that the Internet of Things (IoT) will have on manufacturing is a sure thing. Telstra puts it very clearly when they state that “In an increasingly automated manufacturing environment, having multiple machines communicating with each other and being managed and diagnosed remotely offers benefits that are self-evident.” 

These smart machines pose a unique challenge to the food and bev industry; their delicate circuitry and sensors must be on the production floor but must also be protected from contaminating/being contaminated by the manufacturing process. 

Additionally, these complex computer systems need to be compliant with current and future food safety regulations and be well-suited to withstand increasingly ambitious CIP procedures. 

Now is the time to consider how you can update your existing manufacturing systems to try and account for the changes that are taking place in the industry. Whether it’s investigating new, sustainable production methods, or investing in physical infrastructure that supports new technologies, now is the time to move confidently forward or get left behind. Optimising every piece of the manufacturing puzzle is essential to maintain a competitive advantage.

A Safe Take-Off – Rittal Blue e+ chillers used in aircraft manufacturing

Uncategorized

Aircraft manufacturing. Before a brand-new A320 can be put to work ferrying holiday­makers to sunnier climes, the aircraft has to pass some serious testing at Airbus. However, it isn’t just the aircraft that needs overheating protection to make sure it runs like a dream – the testing hardware needs proper protection, too. Airbus uses Blue e+ cooling units from Rittal to keep its testing facilities in top condition.

The two Airbus workers sit on stools in the cockpit of the Airbus A320, as the pilot seats have yet to be installed. Through the cockpit windows they see not clouds, but 4 monitors displaying the “ground test instructions” they need to work through.

However, the first tests start much earlier. As soon as the fuselage sections of a new aircraft have been assembled, the cables are laid there – and tested. All along the various assembly stations, all newly installed components and systems are immediately tested to ensure they are fully functional. Depending on the configuration of the aircraft in question, the full set of tests for an A320 can take around 400 hours to complete. The majority of these are carried out in Jacobs’ department. Fuelling, taxiing, take-off and landing together with various flight manoeuvres are all simulated on the final assembly line. “Our engineers could fly the aircraft, even though they’re not pilots,” the Head of Ground Testing points out. All functions that are essential to flight safety on the Airbus must be 100 per cent reliable. Only when an A320 has passed all these tests with flying colours can it be sent for delivery and take off from the runway at the Airbus plant in Finkenwerder on its maiden flight.

Simulating Operation

The tasks carried out on the final assembly line include the complete fit-out of the cabin. “Once again, we check everything – from the headphone sockets and in-flight entertainment screens on each individual passenger seat right through to the coffee machine in the galley,” says Jacobs. Testing all the onboard functions requires high-performance hardware that is connected up to the sensors and actuators of the aircraft and used to run complex simulation programs. A total of three computers are needed for the simulations. Each computer is equipped with additional hardware that links up to the components in the aircraft. Lengths of cable as thick as a human arm reach from enclosures containing the simulation computers to the insides of the aircraft. This makes it possible to simulate parameters such as engine speed and the signals from the speed measurement devices. The computers also capture output signals, primarily voltages and volume resistance.

Left: An ice-cold marathon – Cooling units in the Blue e+ range run continuously and stop hardware from overheating. Right: Digital view – No stunning aerial vista for the engineers: Monitors are mounted in front of the cockpit to display the ground test instructions.

Airbus developed the simulation computers, which are installed in a Rittal enclosure on the test bench, in-house. The hardware generates a lot of heat when in use and therefore needs to be cooled – the voltage transformers in particular, which are needed for the connection to the components in the aircraft, can get very hot. “In the past, before we started using active cooling systems for the computers, they often crashed during the summer,” Jacobs recalls. Given how tightly and carefully coordinated the production schedule is at Airbus, that simply could not continue. The enclosures were fitted out with active climate control systems in 2006 to avoid precisely such downtime. Today, there are 28 of these test stations in the Airbus plant, all similarly configured. What’s more, all are fitted with Blue e+ cooling units from Rittal to protect the sensitive hardware from overheating. The reliability of the Blue e+ units is particularly important to Airbus. “If the cooling systems for the simulation computers were to fail, we wouldn’t be able to conduct our tests,” Jacobs points out. The test bench is in use at least five days a week in double-shift operation. “We switch on the cooling units in the morning and they run with absolute reliability,” he says. The cooling systems at the test benches are monitored and, should a unit still somehow fail, a warning light comes on to alert staff.

Guaranteed Energy Efficiency

The idea to upgrade to the energy-efficient Blue e+ cooling units came about while working on energy management for the ISO-14001 certification. Rittal Support gave Airbus crucial assistance during this process, as Jacobs explains: “Thanks to the energy efficiency calculator, we were able to work out in advance how much energy we would save by upgrading to the new cooling technology.”

Well-timed maintenance is crucial to ensuring the cooling units run reliably and efficiently. The main causes of failures are critical component statuses and external influencing factors. Networking the units with the IoT interface ensures the condition of all cooling units is reported to overarching systems. Maintenance teams can then promptly plan the necessary measures and carry out the work at the most appropriate time. These benefits can be taken to the next level in the future by linking up to Rittal’s Smart Service Portal. The networking between the devices and continuous status monitoring ensure critical operating statuses can be identified early on.

The senior managers at Airbus were also impressed by how user-friendly the cooling units are. All parameters can be adjusted easily, using the two buttons on the control panel, and the display depicts status and error messages in clear language. “The quality is right and the customer service we get from Rittal is excellent,” Jacobs concludes. Based on this positive experience, the test benches at the Airbus sites in the USA and China, which are configured in exactly the same way, are also being retrofitted with the new Blue e+ cooling units.
