GENSETS FOR GERMANY

SIXTEEN 3,112 KVA GENSETS FOR A KEY DATA CENTRE OPERATION IN FRANKFURT, GERMANY

This year FRERK has fulfilled a contract for 16 x 3,112 kVA diesel generators with MTU engines and Marelli alternators for data centres located in Frankfurt, Germany. The contract involved providing a emergency power supply for a data centre in Frankfurt. Altogether, sixteen diesel units in soundproof containers (80dB(A) x 1m) have been supplied with an aggregate power of 3,112 kVA / 2,490 kW electr. 15 kV, 50 Hz suitable for ambient temperatures up to 45°C. Each genset features an MTU engine, 20V 4000 G34F, 3F (Data Centre Continuous). The equipment supplied includes features such a Marelli alternator, MJH 630LB4, 3200kVA, 15kV, a double-walled fuel tank mounted under the container with a capacity of 35,000 litres, an overflow tank, fuel cooling and filtering in the container. FRERK undertook the contract from planning to commissioning. The Series 4000 has been designed for power generation continuous/prime/grid stability applications with water-to-air charge air cooling. Wherever there is a demand for utmost reliability, ease of maintenance and compact dimensions, Series 4000 engines are amongst the first choices. Another typical advantage of the 4000 engine is its high efficiency which is based not only on low consumption but also on the relatively low price and a long service life, says the manufacturer. Each gengine features Individual 4-valve cylinder heads with centrally located injectors. The design allows high cylinder pressure and low fuel consumption, low exhaust emissions. The exhaust system has a triple-wall water-cooled manifold offering low surface temperature and reduced heat transfer to cooling system; it is said to be absolutely gas-tight. Each engine offers sequential turbocharging with charge air cooling (turbocharger cut in and out). This means that turbochargers can more closely match and respond to the engine airflow requirements. Series 4000 diesel-powered generator sets can be designed flexibly depending on the application and location. They are available in six different ratings - including Standby, Prime and Data Centre Continuous Power - and can be installed as either mobile or stationary units. The performance range runs from 1,600 to 4,000 kVA (50 Hz) and from 1,125 to 3,250 kWe (60 Hz). Mission-critical systems require faststart capability and one-step load acceptance. The engines have been designed to offer more available power within only a few seconds. The 4000 offers industry - leading load factors up to 100% for data centres and up to 85% for standby applications. This is said by the manufacturer to ‘exceed the established industry norms such as ISO 8528-1 and allows even more operating hours for prime, emergency standby and data centre applications’ - reports mtu. There are currently 25 providers and 54 data centres in the city of Frankfurt which is well-known for its advanced technology. This includes 53 colocation facilities, 36 cloud nodes, 25 Internet exchanges (IX), and 13 disaster recovery and business continuity (DRBC) sites. An important 25,000sqm colocation facility located in Frankfurt’s major internet hub - Kleyerstrasse - is located only 3km from central Frankfurt. One famous city data centre company - TELEHOUSE Europe - is a premium member of Data Center Map in Frankfurt. Offering over 260,000 square feet of Data Centre space in central Frankfurt Telehouse operates Frankfurt’s largest Data Centre campus in “Kleyerstrasse”, the city’s telecommunications hub with a high number of carriers, ISPs located there. The campus includes 3 Data Centres which have access to the DE-CIX, Europe’s second largest Internet exchange with over 500 ISPs and carriers. It is ideal for international corporations with requirements for a wellconnected point of presence in a strategic and highly secure location within Europe’s largest national economy. Current certifications: ISO27001, ISAE3402 (former SAS70), PCI-DSS. Strategically located only 1.9 miles from central Frankfurt, Germany’s major financial and telecommunications district, the Data Centre stretches over a 721,182 square feet site with an immediately available 269,098 square feet of fully-fitted colocation space. This highly secure Data Centre provides one of the largest housing facilities in Germany with reliable environmental controlling systems and scalable power options.
