GENSETS
Genesal Energy has supplied two emergency generator sets to one of the most important Data Centres in Europe, located on the outskirts of the city of Munich, Germany. The gensets have been designed to guarantee constant power supply in the event of a mains failure or any other potential setback. Data Centers or Data Processing Centers (DPC) are complex facilities which hold modern computer equipment and where any failure in power supply can be a serious issue, as all the information contained in these giant servers would be left unprotected. For this reason, DPCs need continuous and constant power supply at all times. A generator set is its greatest guarantee of protection, which is where the client company turned to Genesal Energy to provide experts in installing generator sets adapted to these facilities. A company spokesman commented: “For this client specifically, at Genesal Energy we opted for made-tomeasure generator sets: we designed a bespoke energy solution. “The result translated into two generator sets distinguished by their low sound levels -as they must operate in a great office area- and the fact that they are leakage-proof against any polluting spills (diesel, oil and coolant liquid), as established by the strict environmental legislation in Germany.” During the manufacturing process, the gensets were placed into two 20-foot containers, with two air inlet and outlet baffles of 1200mm in length to lower the gensets’ sound levels by 30 decibels. Furthermore, the exhaust silencers were mounted inside the containers in order to isolate the sound outlet (certification was carried out by an external company). The sets provided were the GEN550PC + GEN850PC and the clients specified enerator sets with low sound levels, as they were to be located in the middle of an office area. Special features included with the gensets were: •Power panel integrated inside the generator set’s container. •Control panel integrated inside the generator set’s container. •Baffles system for -30db. External parts in stainless steel. •Motorised louvres. •Fuel tanks inside the of great capacity had to offer a considerable litre capacity. •The tanks had to come with a with leakage collection tray. •These fuel tanks had to fully incorporate an automatic overfill protection system. •Container with liquid retention system. •Engine room heating to ensure startup in the cold. •Dedicated power outlet busbar due to the great number of conductors per phase. •Overvoltage protection. •GSM control. •Superficial coating of the container according to the ISO 12944 norm, in a C5I finish in the colour requested by the client. •Sound levels certified by an external company according to the ISO8528 norm: -Genset 1: 66 dB at 7m -Genset 2: 68 dB at 7m The diesel GEN550PC has a frequency: of 60 HZ and Power: L (396-940kVA) A Soundproof model (KVA: 550/440) with Three-Phase Voltage, is is powered by a SCANIA DC13 072A (02-13) engine. The power generation engines from Scania are based on a robust design with an optimised cylinder block containing wet cylinder liners, which can be exchanged easily. Individual cylinder heads with 4 valves per cylinder promotes repairability and fuel economy (picture left). The engine is equipped with a Scania-developed Engine Management System, EMS, to ensure the control of all aspects related to engine performance. The injection system is based on electronically controlled unit injectors, which provides good fuel economy and a high torque. The engine can be fitted with many accessories such as air cleaners, PTOs and cooling package, to suit a variety of installations. The genset provides PRP/STP (kVA): 500/550, Emerg. STP (kVA/kWe): 550/440 , R.P.M.: 1800, 4,218kgs, offering Voltage (V): 480/277 - 440/254 - 380/220 - 220/127 - 208/120. The diesel GEN880HC-IN, on the other hand, uses a MITSUBISHI S12A2-PTA engine. Efficient and low maintenance Mitsubishi SA-series engines are fuel efficient because of Mitsubishi’s original direct injection system and turbo. Routine maintenance has become easier than ever before, with increased intervals for changing the oil. New materials in the exhaust system have a positive effect on durability (pic below). This set’s specifications are as follows: Frequency: 50 HZ, Power: XL (826-3900kVA). A Soundproof model (KVA: 880/704), this offers PRP/STP (kVA): 800/880, Emerg. STP (kVA/kWe): 880/704 and produces a voltage of 400/230 - 415/240 - 380/220.
