Purchasing generator sets, A critical decision
Purchasing a generator set is an important decision, as it often involves making significant investments—either to expand a rental fleet or to equip a site with an emergency generator set.
Below, we present the three key factors you should consider before purchasing a generator set.
Operating conditions and installation location
The conditions under which the generator set will be used and its location play a major role in selecting the most suitable model. More specifically, they may lead us to opt for one engine or another, or to adapt the equipment accordingly.
- Environment and operating site: If the generator set is going to be exposed to harsh environments, this must be taken into account. Extreme conditions of altitude, temperature or humidity can result in significant power losses, also known as derating. Of course, humidity can also affect the surface quality of the machine, encouraging corrosion if adequate precautions are not taken (such as stainless steel canopies or surface treatments, for example).
- Available space at the installation site: Before committing to the installation of equipment, it is essential to ensure that there is sufficient space for its placement, allowing for door clearance and enabling proper installation and subsequent maintenance tasks.
Required power for your energy needs
Being aware that environmental conditions themselves can affect the generator’s power delivery, the next step is to determine the energy requirements to be met by the generator set.
It seems logical to ensure that the chosen generator set will be able to support the installation’s load. Some points to consider include the following:
- Total load: Calculate the total power required by all the devices and equipment the generator will need to supply. As specialists, we can help you with this.
- Demand peaks: Consider potential demand peaks to ensure the installation runs continuously without interruptions.
- Simultaneity factor: Another essential aspect is understanding whether all the loads in the installation will operate simultaneously and to what extent. This will help avoid over-dimensioning the system.
- Safety margin: It is advisable to choose a generator with a slightly higher capacity than required to ensure efficient and long-term operation. However, this should not lead to unjustified over-sizing, as it will not only increase costs but may also affect the performance of the generator itself. In this regard, we will help you determine the optimal power to meet all of the above points.
Fuel type: Diesel or petrol
When it comes to choosing the type of fuel to be used, it’s not always possible to choose freely between one or the other. The required power will largely determine the options available.
- Diesel: Diesel generators are suitable for both demanding continuous operation and emergency applications. They are typically used where medium or high power equipment is needed. Depending on the needs and objectives of the project, you may opt for generator sets from our Industrial range, Balance Emergency or Rental Plus range.
- Petrol: Petrol generators are suitable for low-power applications and are generally more economical in terms of upfront cost. They are a good option for occasional professional use or for residential settings. Within our portable range and inverters, you’ll find many options ranging from 2.4 up to 24 kVA.
