Generators are divided into different categories according to the way and the place they are installed. We will explain to you what those categories are.
Equipos móviles para obras o proyectos en zonas aisladas, generadores de emergencia estáticos situados en el interior de fábricas, grupos electrógenos exteriores operando en áreas densamente pobladas… Todos ellos necesitan cumplir diferentes requisitos, que acaban marcando su diseño y su tipo de montaje.
Aunque esos requisitos pueden ser diversos y numerosos, se puede decir que hay 3 variables básicas que acabarán caracterizando a un generador:
- First of all, the mobility which will be required by the generator. Are we talking about a generator which will be installed in a fixed location, never to be moved again, or is it a generator which will be used in various locations?
- Secondly, its isolation from the environment. Will the generator be installed inside a building or will it be located outdoors?
- Finally, the acoustic requirements of the environment in which it will be installed. Will it be of critical importance to maintain a low level of decibels or will there be no restrictions in matters of acoustic pressure?
Once these questions are answered, we will be able to choose the type of generator most suited to the requirements of our project.
The basic types of installation
Despite the fact that there is an infinity of personalization options, there are 3 types of installations according to the parameters mentioned above.
1. The open stationary installation
This type of installation is foreseen for projects in which the generator is installed inside a building and it does not need to be moved once installed. Consequently, the generator does not need any casing to protect it from inclement weather, nor does it have any mobility device.
The generator will be installed on a steel bedplate (with or without an integrated fuel tank), capable of sustaining the static mechanical requirements, as well as the vibrations to which the generator will be subjected throughout its service life.
2. The stationary sound-damping installation
When the generator will be exposed to bad weather conditions, will be stationary and the sound level it produces will have to be low, this type of installation is the ideal one.
The generator is encapsulated in a galvanized steel cabinet, protecting it from inclement weather. The inner part of the hood is covered by sound-damping material, which allows for the reduction of the sound level which is emitted. Therefore, this type of installation is adequate in applications where noise is a crucial factor.
3. The mobile sound-damping installation
This is the type of generator which is usually seen in provisional installations (events, film shootings etc.). Its differentiating feature is that this type of generator must have the possibility to be moved to where energy is required; consequently, it will be installed on a trailer.
The device is placed on some special anti-vibration dampers, capable of sustaining the sheer stress (or lateral deformation) which can happen during circulation: factors such as braking, acceleration or bumps. In this way, one manages to protect the monoblock (the engine-alternator group) and to ensure the generator’s functioning and durability.
