Different types of diesel generators require specific site planning and preparation. In this article, we are going to be looking at preparing to install three of the most popular backup generators; enclosed permanent diesel generators, enclosed portable diesel generators and permanent diesel generators installed inside a building. You can find a whole host of generators over at Able Sales.
Site Planning – Enclosed Permanent Diesel Generators
It is very important that you check the national & localized planning guidance and the relative manufacturer’s safety and usage documentation. In the planning process be sure to address the following:
- The fuel supply has to be accessible by fuel truck
- Include the provision for a security fence
- Ensure that you decide on below or above ground electrical and fuel connections in this initial planning stage
The next step is planning the concrete pad. It is also important here to check the local building codes. Avoid setting the generator on gravel as it may destabilize the gravel base when it vibrates. Some of the things to consider when planning the concrete pad include:
- The Ambient temperature of the concrete pour
- Remove bubbles in the concrete
- Decide if the concrete will be reinforced or not
- Ensure that the pad is at least 1.5 times the length and width of the generator
- You should also consider using concrete anchors to attach the generator and fuel supply to the pad.
Site Planning: Enclosed Portable Diesel Generators
One of the greatest advantages of portable diesel generators is that they don’t require too much site preparation. Here are a couple of things you need to consider:
- Ensure there is good road access to the site
- Ensure that there is also sufficient head room and side clearance both on site and in transit
- Ensure you have adequate fuel since a large generator may need 650 liters of fuel per hour
- A large generator may weigh more than 30,000 kilos. The rear wheels may need reinforcement depending on the ground conditions.
Permanent Diesel Generators Installed Inside A Building
Generators that are meant to be installed inside larger structures are often self-contained. This means that the fuel system, engine and cooling system are well aligned and mounted on a skid. It is therefore just a matter of moving the skid to the facility. Consider the following:
- Ensure adequate headroom and side clearance to move the skid into position
- Make sure you also have adequate lifting equipment such as a large forklift to facilitate the process.
- Make sure that the concrete pad is located in an area that will make maintenance easy.
- Follow the manufacturer’s instructions when attaching the generator skid mounts to the pad.
- Ensure the room has adequate air supply
- Make sure that the fuel supply system is up to all relevant codes and regulations.
- Run electrical drops after installing the generator. You can follow the manufacturer’s specifications and regulations.
- Install an exhaust system for the generator as well as cooling air ducts and louvers.
