The Differences Between Single, Bi-Fuel and Tri Fuel Generator

The generator you choose to light up or heat your home or business depends on your needs and preference. Therefore, before selecting a generator, it is crucial to understand the different types available in the market. They are three types of electric generators: the single fuel generators, dual fuel, and the tri-fuel generators. Here is a look at what sets each one of them apart from the other.

Electric generators normally run on four types of fuels including liquid propane, gasoline, natural gas, and diesel. A single fuel generator is different from other types of generators as it only uses one of these fuels; in most cases, it works on either gasoline or diesel. Dual fuel generators on the other and will run on two fuel types.

Therefore, you can easily use a different type of fuel if the one you are used to becomes scarce. This means that if your dual fuel generator uses propane and it runs out of this fuel, you can use gasoline instead. The fact that this type of generator also runs on propane means that it is different from the single fuel generator since propane offers clean-burning benefits.

Just as the name suggests, a tri-fuel generator uses any one of three fuel types mentioned above. Therefore, you can run your generator on gasoline, natural gas or propane if you so wish. Just like the dual fuel generator, the tri-fuel is also preferred by users for its convenience when one type of fuel is scarce.

Are These Type of Generators Good?

It is clear that multi-fueled electric generators are the most preferred than single fuel counterparts. Here is a look at some of the benefits users stand to enjoy when they choose a dual fuel generator.

Versatility and efficiency

Since a dual fuel generator uses two types of fuel to generate electricity, it means that you can use a cheaper alternative when one fuel becomes expensive to acquire. Therefore, you will stand a chance of saving on cost especially if you are using the generator to run your business.

The efficiency of this type of generator is also overwhelming. It can provide stable electric power for all your electrical appliances for a longer time.

Longevity

You will also enjoy the durability that comes with a dual fuel generator in terms of electric power supply. Since they have two tanks or storage units, you can let your generator run on one fuel then automatically switch to the next one if the previous one runs out.

Convenience

Since this generator switches automatically when one fuel reservoir runs dry, this means that you don’t have to stop your errands from going and checking it.

Also, you could start with gasoline then, later on, change to propane. This gives you the chance to make use of a fuel that operates best under some weather conditions and keep aside those that don’t. This means that you will be ahead of your business competitors in every manner.

Eco-friendly

Natural gas is known to burn cleaner than diesel; therefore, a mixed fuel means there will be lower emissions than a generator that is only powered by diesel. You don’t have to invest in a new genset if you want to meet guidelines for non-emergency use. Therefore, you stand a chance of qualifying for a cost-saving and eco-friendly operations when you make use of this type of generator.

Availability of natural gas

The availability of natural gas is the other potential benefit of a dual fuel generator. It is essential to understand that a good number of industrial businesses already have a natural gas supply readily available. Since this supply does not need any storage, it eliminates the need to maintain and the space occupied by large fuel tanks. Therefore, in case there is an emergency, the natural gas will always be available.

Less expensive

Since natural gas is currently less costly as compared to diesel, using a dual fuel generator becomes the ideal solution for people who are budget conscious. It is also essential to understand that natural gas burns cleaner than diesel. Therefore, your generator will be subjected to less routine maintenance which is different from generators that use diesel.
