Innovation reduces energy costs

Harnessing the power of compressed air more reliably and economically is an effective way to drastically cut energy costs. A host of innovations on display at Hannover Messe shows how modern technology makes it possible. Even compressed air stations that were optimised for performance at the time of installation can yield further savings of up to 10 percent if the latest technology is used.
The whole is more than the sum of its parts – a saying that also applies to compressed air station design. Efficiency and economy of the individual components isn’t everything. Well-coordinated, optimised interplay of all components is necessary to ensure compressed air production remains as reliable, efficient and economical as possible.

When it comes to compressed air production, the golden rule is to consider the entire system as a whole and not just the individual, isolated components. While the most energy-efficient compressor or dryer offers a clear advantage when the objective is to reduce energy costs, large sums can still be lost when the compressor and dryer are poorly coordinated or do not work seamlessly together.

Analysis now available online
ADA2_KaiserFirst it’s important to know what the business’s actual compressed air requirements are. Compressed air engineering specialists can precisely determine this information via an audit; the latest generation of high-efficiency analysis tools is being showcased in Hanover. This includes the ADA 2 analysis tool from Kaeser Kompressoren a web-based system for compressed air duty-cycle analysis. It supplies both measurement data as well as the system data from the audited station and is capable of quickly generating an initial report for the operator. The data can then be imported into the tried and trusted Kaeser Energy Saving System (KESS), which allows compressed air operators to devise a step-by-step plan to reduce energy costs, and even offers a comparison of the investment costs associated with the various energy-saving options. Independent comparisons of various system variants are also readily available to enable selection of the most efficient one.

Clear facts to improve the system
Once the information fetched, it is possible to work on the whole and on individual components

  • Controllers to ensure maximum efficiency
  • Efficiency of the rotary screw compressors (thanks to large cooler surface, IE4 motors and more)
  • Enhanced thermal mass performance benefits refrigeration dryers
  • Compact and efficient dryers, rotation dryers
  • Filter technology: energy-saving and environmentally friendly

Huge savings to discover at Hannover Messe
At the Hannover Messe Preview a few weeks back I discovered that actually compressed air can be seen as necessity evil or as a valuable resource that can be improved (and thus generate cost savings, better environmental protection and greater efficiency).
Even operators of optimally designed and configured compressed air systems can further cut energy costs by up to ten percent by taking advantage of the latest technological innovations. Operators still using older components or systems in which the individual components are not optimally coordinated can also achieve savings in the double-digit range.

To be discovered on booth D42 in Halle 26 (and in our next issue)

Hannover Messe 2013

Energy efficiency as major trend

The Hannover Messe preview took place last week in Hannover and I was lucky to be there to discuss with some exhibitors and the organisers. It was amazing to see that at least half of the companies I visited talked about energy efficiency. It is still a major trend, let’s see an example.
Kaeser_Eurotec_Hannover Messe
In any workshop people are using compressed air and most of the time that resource is seen as necessity evil and anyhow not a topic top deal with to add value to the company…. things may be seen differently though.

Energy-saving innovation
I’ve met with Kaeser Kompressoren specialists and I’ve learned that actually there are a lot of savings to do with compressed air.
The company will unveil new models at Hannover Messe with innovative energy-saving solutions like refined flow optimised rotors and the use of prime efficiency motors for instance. Their Sigma Air Manager is able to deal with several machines and allows its user to precisely adapt compressed air management and then reduce consumption. But there is more!

Compressed air audit
A complete new service is about to be launched largely. It consists of small devices put on every machine dealing with compressed air in a factory… these tools send all information about consumption and use of compressed air through Internet… Kaeser offers then its expertise and the right analysis tool to propose a better use of the compressors in use. Only that step allows companies to save a lot of energy (and money indeed). This solution works with Keaser compressors but also with any other brand. And customers buy results! The audits allow Kaeser’s experts to guarantee a certain level of saving. ROI can be precisely planned.

We will come back on that important issue very soon, stay tuned.

Energy-saving FCR brake motor

Since 16 June 2011, European Commission regulation 640/2009 imposes the use of class IE2 high-efficiency motors. Brake motors are not currently affected by the application of these new directives. Nonetheless, Leroy-Somer has chosen voluntarily to adopt an energy-saving approach and is already offering a new generation of high-efficiency brake motors.

The marketing campaign of the company is quite original and raises questions on sustainability, it is perfectly adapted to nowadays’ concerns.

This new generation combine the FCR series of electromechanical brakes with high efficiency drive mechanisms integrating the most innovative drive technologies for both fixed and variable speed.

Modular concept
FCR is a tried-and-tested series of failsafe safety brakes and emergency stop brakes, offering a variety of options in optimised frame dimensions. Its modular concept makes it perfectly suited to any application. The ultimate multi-purpose safety device, its low inertia means it can withstand repeated braking operations: up to 6000 per hour. It can even be fitted with a booster system which reduces the brake reaction time. Carrying the CE mark for machine safety and conforming to IEC standards for Europe, it is also C-CSA-US approved for North America and has a Nemacompliant mechanical finish.

Asynchronous versions of the FCR can be mounted on the new IE2 highefficiency motors in the LS2 range, from frame size 80 to 160 mm, with aluminium or cast iron frame, for power ratings from 0.75 to 11 kW. Designed to deliver significant energy savings, LS2 FCR brake motors offer a wide variety of adaptations, thanks to numerous mechanical options (non-standard flange, special shaft, customised terminal box, etc) and electrical options (special connections and voltages, thermal protection, etc). To take energy saving to the next level, FCR can operate at variable speed.

…and synchronous…
With unrivalled efficiency levels, Dyneo® permanent magnet synchronous motors are one of the best-performing variable speed solutions currently available on the market. Using state-of-the-art technology, the FCR Dyneo® brake motor (with an IP55 motor in the LSRPM series, from 4.8 to 36 kW) performs exceptionally well in terms of energy, and is particularly suited to all applications involving heavy-duty use (S1 duty), such as bulk conveying in the mineral and cereal industries.

…at your disposal
Finally, the FCR brake motor is registered in Leroy-Somer’s “Guaranteed Availability” programme, with delivery times to the customer within 3 to 15 working days depending on the version.
