Danfoss VLT Drives Control Energy Consumption at LEGOLAND®

1900,000 kWh of electricity saved per season

The Vikings River Splash is popular in LEGOLAND®. It also consumes more energy than nearly everything else in the amusement park.  This is why regulating the water flow in the attraction is of supreme importance.  The goal is to use only the necessary amount of water to send the guests on a wild ride in the tub-shaped boats.

“By installing Danfoss VLT 6172 132kW frequency converters on the two pumps of the ride we have reduced energy consumption. At the same time it is now easier to regulate the water volume because the frequency converter ensures that the pumps only circulate the necessary volumes of water”, says Anders Christensen who works as an electrical technician at LEGOLAND.

Electricity consumption has been reduced by 190,000 kWh per annum, and at the same time it has become easier to regulate water flow.

Reduce Energy Consumption by 13% with the VLT controlled NH3 Compressor

 

Applying a frequency converter to a NH3 compressor reduced the energy consumption by 13% at one of the world’s leading palm oil refineries in Malaysia. This equals an energy savings of over 240,000 kWh and the return on investment was approximately 20 months.

Challenge
The palm oil refinery is striving to advance environmental protection and to increase profits by reducing energy consumption. Understanding that applying frequency converters to compressors can result in significant energy savings, they wanted to retrofit a 400 kW ammonia screw  compressor with a frequency converter. The customer also wanted to integrate the frequency converter into the existing PLC and DCS systems. After evaluating several suppliers, the customer selected Danfoss because the Danfoss sales team has the expertise to support the integration of the frequency converter into their existing system.

Application Solution
The compressor is being used with two other compressors in an industrial refrigeration system. The frequency converter will allow the first compressor to serve as the trim compressor and will control the capacity of the system. The first compressor and frequency converter will operate continuously. The other two compressors operate at full load when needed for additional capacity. The compressor manufacturer advised that the minimum speed of the compressor is 50%. As a result, the VLT® drive would operate the compressor down to 50% with the slide valve completely open. At 50% speed, the compressor speed would be maintained and further capacity reduction would be performed by the slide valve.

Benefit
Energy usage was measured for one month so that the savings and the payback could be determined. The chart shows the energy consumption of compressor 1 with the frequency converter compared to the energy consumption of the two compressors without frequency converters. Applying the frequency converter to the compressor reduced the energy consumption by 13% (00 kWHrs). This resulted in a cost savings of over $66,500 per year. The return on investment was approximately 20 months. Subsequently the  customer has retrofitted many more compressors in the range of 160 kW to 400 kW, achieving further significant energy savings.

This is an application by Danfoss.

Danfoss – VLT® 690V high-power frequency converters

These high frequency converters optimize large-scale fermentation processes.

Fermentation is important for large-scale production of industrial enzymes and careful control of the fermentation process is necessary to ensure optimal microbial metabolism.

Seed from one fermentation tank is transferred to the next, ending up in the main fermentation tank in which the temperature, pH and dissolved oxygen must be carefully controlled to optimize the enzyme production.  Cell metabolism develops heat and cooling water is used to maintain a constant temperature in the tank.  Sterile acid and alkali are added to regulate the pH.  The required degree of dissolved oxygen is maintained by adding sterile air and stirring, so that their disperses into tiny bubbles.

25% Cost Savings Compared to Other Conventional Systems -Danfoss VLT One Gear Drive

Energy Efficient, Flexible and Reliable

Times change and with the current climatic and financial issues, the wheel has turned full circle and there are strong arguments for the adoption of high efficiency technology along with equipment rationalisation across the drive users’ factory or production facility.  That, and in the face of ever increasing competition and growing political and social pressures, producers are constantly looking for new ways to cut costs, reduce energy consumption and improve the environmental compatibility of manufacturing systems.

Solution
Danfoss VLT® FlexConcept 25% cost savings compared to other conventional systems.

Heineken brewery upgrades production line with VLT® FlexConcept®

A customer success story from Danfoss Drives

The famous Austrian brewery, Wieselburger constantly aims to use the newest technology to ensure high product quality and efficiency. Danfoss VLT® FlexConcept® helps them secure flexibility, fewer motor variants and energy efficient operation.

The brewery in Wieselburg can look back on years of tradition. Starting as an independent brewery in 1650 it is now the cornerstone of today’s Austrian beer metropolis, Brau Union Österreich Group, which is owned by Heineken. Skilled brewers and newest technology ensure a sustainable and environmentally friendly production in order to achieve the highest quality.

Efficient Upgrade of Fill Line

The brewery in Wieselburg can look back on years of tradition. Starting as an independent brewery in 1650 it is now the cornerstone of today’s Austrian beer metropolis, Brau Union Österreich Group, which is owned by Heineken. Skilled brewers and newest technology ensure a sustainable and environmentally friendly production in order to achieve the highest quality.

Unchained Advantage

One of the main benefits of installing OneGearDrives is that the factory no longer needs chains to connect the gearbox to the conveyor shaft, as the drive is mounted directly on the conveyor shaft.

“Chains alone introduce system efficiency losses of up to 10%. Also, they are cumbersome to fit and add additional maintenance costs for spare parts and lubrication. The OneGearDrive solves this elegantly and efficiently by simplifying the installation. The hygienic design of the drives also makes it easier to clean, as there are no cooling fins, sharp edges and other areas where dust can accumulate,” explains sales engineer Michael Hitter from Danfoss.

Easy Integration

By sharing the same design and operation principles as the brewery’s many other VLT drives, the new drive solution was relatively easy to integrate into the existing setup. The brewery already had positive experiences with the Danfoss frequency converters that were already installed in a central control concept, where the frequency converters are grouped in switch rooms or panels.
