Unilevers waste minimized with PowerMoniMain


New sensor technology finds errors and optimize the production at Unilever

In short time Energy Consultant and CEO of AX Energi, Mr. Peter Bruun, has managed to optimize the performance on parts of the installations at Unilever’s production by implementing a new multi sensor.

The sensor is called PowerMoniMain and has been developed by the GreenTech company ReMoni. The sensor provides real-time data, electricity metering, operations information and gives you an overview of the current and historical energy consumption. A PowerMoniMain enables you to monitor various technical installations and units at the same time – all day and all night.

Improve operational efficiency 

As most Energy Consultants, Peter Bruun has been using a lot of time trying to detect the invisible power consumption by localizing the resource wasting installations. He purchased a PowerMoniMain, which made it possible for him to optimize parts of the production at Unilever in record time.

”One of the benefits with PowerMoniMain is, that you get data on the performance and consumption of various units at the same time,” Peter Bruun says: ”With continuing data for various installations I have got an insight, which I haven’t got earlier – this makes it easy for me, since the data patterns rapidly point out the problematic units.”

A PowerMoniMain can monitor power consumption on up to 15 technical installations at the same time. According to Peter the new, concrete insights in the current and historical consumption makes it possible to optimize the facility. For instance, it becomes easy to find installations that are using power during night even though the production has been shut down.   

Peter Bruun likes to stay updated on new technology. For this reason, he immediately bought a PowerMoniMain when it was launched. From then it did not take long before it was installed at Unilever – a company focusing on savings and on reducing power consumption and waste.

Peters Bruun’s first project at Unilever revealed a yearly energy saving of DKK 86,000 – equivalent to EUR 11,600 – within the first 10 days. 

Data appeared in ReMonis cloud-platform ReCalc shortly after sensor and gateway had been installed, and from there it did not take many hours before he had found the problematic installations. Based on time and consumption it turned out that the compressor and some heating elements were consuming a lot of power outside of production hours.

Get an operation pattern for all kinds of electrical motors

No matter which power consumption or which electrical installations you would like to monitor over time, you can use a PowerMoniMain. You get an operation pattern and power monitoring in switch boards and for all types of electrical motors such as compressors, pumps, ventilation systems, production equipment, CNC-machines and much more. In addition, PowerMoniMain can be used for monitoring the power consumption of charging stations or the actual power production of solar panels.

ReMonis PowerMoniMain provides data about the actual number of operation hours of the machines so that maintenance and service can be planned based on real data . With a high and continuing data sampling rate you get valuable data for an Overall Equipment Effectiveness (OEE) analysis of your production equipment.

”Luckily it is  clamp-on, on the outside of the cables and a PowerMoniMain does not fill up space in the switch board,” Peter says: ”Well, actually the sensor can also stay in the switch board, so that we stay updated on the power consumption of this product line.” 

Peter confirms that it is easy to install a PowerMoniMain and that it takes significantly shorter time to get up and running than other equipment for power consumption. Practically a PowerMoniMain is installed in a switch board. From here the ReMoni gateway is sending data wirelessly to the cloud-platform ReCalc – and that’s how simple it is.

PowerMoniMain can meter and monitor various machines at the same time and be used for both screening purposes and permanent power metering.

Reducing energy waste in retail chains requires flexibility

Research from the University of Southern Denmark shows that flexible and accurate monitoring of light, ventilation, refrigeration, and freezers in retail chains reveals hidden resource waste.

When it comes to optimizing resource consumption, there is room for improvement in the retail industry. This can be detected by using ReMoni sensors that measure the consumption profile in technical installations.

“We move the wireless sensors from equipment to equipment and measure consumption directly on the outside of the cables,” says Professor of Center for Energy Informatics at the Southern University of Denmark, Mikkel Baun Kjærgaard, about the FlexRestore research project supported by EUDP.

“In this way, we get a quick and concrete response to how the consumption profile looks. This procedure reveals energy waste as well as deliver important data. The project took us less than a day, and the data speak for themselves. For example, we see the influence of different ways to fill up products, which can lead to energy waste,” Mikkel Baun Kjærgaard says.

The future is flexible

The future’s way of producing power is becoming more flexible in terms of resources like solar and wind energy. That’s why the future monitoring of resources must be more flexible and detailed, explains the professor. This is where the ReMoni sensors have an important say. Mikkel Baun Kjærgaard concludes:
“The sensors are wireless and it makes our work easy because they are so flexible. They stand out because they are so easy to work with.”

Project in a daycare center reveals huge resource saving potential

There’s a great amount of money to be saved in public buildings, businesses, and institutions.

Something, the use of ReMoni’s wireless IoT sensors demonstrates in a project, run by Danish Energy Management, the Technical University of Denmark and Aarhus University.

Fact-based decisions are in high demand when it comes to energy optimization in private as well as public companies and institutions. This is something Jakob Nørby, who works as a market manager for energy innovation at DEM (Danish Energy Management) explains:

“We want our customers’ decisions to become more fact-based than the case is today. I believe that it will lead to more and more robust cases for energy optimizations/renovations.”

As part of the project called E-snap, supported by the Danish Energy Agency,  a handful of ReMoni clamp-on IoT sensors was installed in a local daycare center in Aarhus. The purpose was to recalculate the saving potential of, among other things, the heating system in the building. The sensors measured certain temperatures on the district heating pipes, which on the surface otherwise worked as they should. However, after the sensors were set up, the measurements showed that the heating system did not work properly:

“Our needs typically arise when we suspect that technical plants do not perform optimally and thereby have a huge energy loss. This suspicion will be able to be confirmed by means of, for example, IoT sensors,” explains Jakob Nørby.

The measurements in the daycare center clearly showed that improvements were needed.

Jakob Nørby says that the starting point for the project was focused on the ventilation – which 

should only run in the opening hours. But this also turned out not to be the case. 

Monitoring pays off

After the sensors were set up, the return of investments (ROI) had doubled.

“We knew there were some errors in the technical installations. Sometimes it just does not work as expected. But we did not know that the case was as strong as it actually turned out to be,” explains Jakob Nørby, while emphasizing that he is an impartial advisor and that there might have been other sensors than ReMonis that could be used in the project. However, when the choice fell on ReMoni, it was because of the complete solution. Everything works together from the start and when the sensors are mounted on the outside of the cables, everything else runs automatically.

Jakob Nørby sees great possibilities in ReMoni’s solution.

“In fact, there’s not a building we cannot find savings in. Office buildings, public institutions, and factories – just to name a few. We can quickly and easily get an overview of the energy situation. And at a much lower price than we have seen in the market so far.”

Silkeborg Municipality beats Legionella

Climate change does not only affect the weather but also spreads dangerous bacteria that forces municipalities and professional building managers to think innovatively when it comes to preventing and identifying Legionella in public buildings and institutions

Identifying exactly where in the pipes the bacteria is spreading has in the past been complicated. Inspecting miles and miles of pipes can be a challenge, so when Silkeborg Municipality started screening local nursing homes for Legionella, they welcomed ReMoni’s solution that – not only tells where the outbreak is located – but even predicts where it’s likely to appear:

“We have a limited amount of time to solve our tasks. With the sensor FlowMoniSpot we can get the results immediately and get the job done quicker,” leading engineer Jesper Buchardt explains.
“We place the sensors strategically to monitor where there’s backflow or accidental warming of the cold water, which should normally be below 20 degrees Celsius to avoid bacteria.”

Because the sensors are wireless and flexible, it’s easy to monitor single units which give accurate results. 
“We do have other monitor equipment available, but a configuration of the systems can both be time-consuming and challenging. ReMoni’s sensors really live up to our expectations, because of the easy installation. We can read the results right away,” Jesper Buchardt explains. 

By combining artificial intelligence and IoT, the sensors register the temperature and ReMoni’s solution can, therefore, predict where there’s a risk of bacteria formation. If there’s a risk, an alarm is sent to the building manager in charge. In that way, it’s possible to prevent the outbreak.

“As a municipality or business, there’s a lot of money to be saved because you can install the sensors yourself and you can read the data in real time – and, we offer the solution at a fraction of the other available products on the market,” CEO at ReMoni, Bo Eskerod Madsen explains.

Taking the pulse on Odense City with clamp-on IoT sensors

Odense City IoT sensors

Odense City is in a rapid, fast paced development.

Everywhere, new buildings sprout and create an increasingly dynamic cityscape, where the diversity of the public buildings stretches from innovative and modern libraries, medieval castles, public restrooms, protected ancient houses and museums of art and history, in which the city itself is full of.

The public buildings buzzes with citizens and tourists that creates energy – energy that Kristian Bork takes the pulse on each and every day, in order to save resources and, of course, cold cash.

From his desk in the Building and Maintenance department – in the third-biggest city in Denmark – the systematic building maintainer controls everything from public restrooms, community schools, museums and cultural institutions. It’s Kristian’s responsibility to maintain the building and all the installations within it – something that requires innovative solutions, because of the vast challenges of the different buildings.

Reducing the carbon footprint
Beside the maintenance, Kristian works to reduce the buildings carbon footprint.

As a part of Odense’s green Energy Lean project, the city wants to lower the CO2 emission from 244 public buildings with 40% – as inexpensive and effective as possible, of course.

Energy monitoring has until now been expensive and complicated, so these challenges require a brand-new way of thinking.

That’s one of the reasons why Kristian is excited about ReMoni.

By clamping on ReMoni’s IoT sensors on the outside of electric installations, water and heating pipes, Kristian keeps track of the energy consumption by logging into the software program ReCalc, where he receives alarms in case of overconsumption and leaks. Kristian explains: 

”ReMoni makes mapping the entire building easy. Without cutting any wires, I can monitor all energy consuming devices – not just the building’s main measurer. It’s easy to set up – you don’t need to have any prior knowledge to install it. Troubleshooting is a piece of cake and because of artificial intelligence, you can easily predict and prevent damages and waste of resources,” he says and rounds up:

“It’s brilliant.”
