Ventilation systems

Your ventilation for emergency power supply in safe hands

To guarantee a high level of security, the downtime should be as minimum as possible. Generators provide emergency power, in case of a power failure on the local network. To provide emergency power, the generators have to be filled with fuel, provided with ventilation and take care of flue gas exhaust through penetrations in the enclosure or the building. It is important to reduce the noise emission as this is crucial to comply with the environmental legislation.

  • Software: Alara-Lukagro uses advanced technologies. CFD (Computational Fluid Dynamics) and other finite element methods modeling, helps to understand specific challenges. Our own noise calculation program give us accurate information regarding the measures that are needed to comply with all requirements.
  • Ventilators: Will be project specific, selected according to ventilation cooling air, pressure requirements and demands according to explosion (ATEX) or variable speed selection (frequency regulators).
  • Silencers: Alara-Lukagro offers a wide range of silencers for the air inlet and outlet. Cylindrical silencers or square silencers with splitters, staggered splitters or splitters with Helmholtz-resonators (1/4 lambda). Every room is different in terms of dimensions, case-radiated heating/required cooling capacity and source capacity. Based on this information we select the right silencer with the suitable pressure characteristics.
  • Flue gas: For draining of toxic gases Alara-Lukagro can provide smoke/exhaust gas silencers including pipe systems, such as a CE marked chimney. All duct systems can be provided with thermal and acoustical insulation.
  • Filters: All ventilation systems can be provided with filter systems, capable of handling variable flow rates, fire dampers, rain screen louvres and roof cowls.
  • Experience: Alara-Lukagro has a wide range of experience in standard ventilation systems and complete ventilation systems with special demands in extreme environments, e.g. extreme weather conditions, limited space, high temperatures, corrosive environments, inclusive complete constructions and chimneys. All products will be delivered with the necessary certification.

Acoustic enclosures & containers

Your generator for emergency power supply in safe hands

Alara-Lukagro can provide different types of acoustic enclosures & containers when the generators are installed outside of a building. The enclosures and containers offer good protection against radiated noise emission and weather conditions. The housings are acoustically and thermally insulated, provide necessary ventilation conditions and can include fire protection.

  • Acoustic panels: The enclosure is built up with individual panels which are assembled on location to create a robust housing. The panels with integrated steel construction provide a high sound insulation, whereby the residents do not complain about sound emission of the installation.
  • Containers: Instead of assembling an enclosure on site, it is also possible to integrate all the required equipment in a container. This container can be delivered as plug-and-play unit. Alara-Lukagro will take care of the complete design, construction, including electric and mechanical systems and including delivery on site.
  • Ventilation: The required air flow will be calculated based on the custom requirements.
  • Calculation: During the design process, different strength calculations will be executed. CFD may be used for the calculations of air flows and temperature distribution. Alara-Lukagro use also other finite element methods to do different type of calculations that benefits the mechanical and acoustical design.

  • Walls: It is possible, with the sound insulated walls of Alara-Lukagro, to part entire rooms. The walls can be installed later and therefore it is possible to install large objects, like engines, in the mentioned rooms. In addition, the sound insulated walls, which are characterized by sufficient bearing capacity and wind resistance, can be used to reduce the radiated noise emission, for cooling machines on the rooftop, towards the environment.
  • Vibration insulation: Generators causes vibrations that are tangible at great distances. By setting up the generators on vibration isolators, vibration transfer to the rest of the structure can be prevented.
