Hanover, 30 August 2010. Energy savings of up to 40% could be achieved by using an energy-saving conveyor belt for unit load conveying systems. Field tests have demonstrated that this is indeed a realistic figure.
Forbo Siegling first reported the innovation, which is known by the name Amp Miser™, around two years ago. A permanent sliding layer on the underside of this type of belt reduces friction, resulting in a lasting reduction in energy use. The belts have undergone extensive testing in the field by well-known logistic center and airport operators. It is now clear that Amp Miser™ conveyor belts require substantially less energy compared to conventional belts. Almost all test results showed energy savings of between 25 and 40%.
An Amp Miser™ belt used on a 16 meter long horizontal parcel conveyor at a distribution center run by the T.N.T. logistics group at Kingsbury, England, achieved energy savings of 39.8%. Düsseldorf Airport, which trialed the belt as a 45 meter long collector belt behind the check-in, reduced energy consumption by 32.4%. At Schiphol Airport in Amsterdam, an AmpMiser™ used on a horizontal luggage conveyor saved more than 30% energy.
Significant savings were also reported by airports in Denver, Dallas, Copenhagen, and by the Siemens Airport Center in Fürth/Germany. Parcel and goods distribution depots in Aarhus, Madrid, Manchester, Sydney, Hamburg, Bremen, and Oldenburg recorded substantial savings too.
A profitable option for operators: an Amp Miser™ belt on a conveyor length of as little as 10 meters with an average load of 250 kg reduces energy costs by approximately 150 euros per year. “This may not look particularly impressive at first glance. However, if you gross that up for the entire plant, savings of around 500,000 euros and more per annum are quite realistic for big airports”, says Bernd Langreder, airports and intralogistics manager at Forbo Siegling. “Thus, investment costs may already be recouped after little more than a year.” And, as Langreder points out, apart from the conveyor belt a lot more fine-tuning could increase the efficiency of luggage conveyor systems even further. Forbo Siegling currently offers four types of Amp Miser™ belts from European production, two of which are of the flame-retardant quality required at airports.
The name Amp Miser is derived from the words ampere and miser, i.e. the belt is an “energy miser”. The sliding layer on the underside of the belt acts as a dry lubricant which reduces friction during operation on conveyor decks. As a result, it is possible to install long lines with only one drive.
Because of their energy saving potential Amp Miser™ conveyor belts also cut CO2 emissions (if fossil energy is used) and thus contribute to climate protection.
