The difference between open, canopy and containerised generators

When it comes to purchasing either a diesel or gas generator, it can sometimes be tough to know which generator is the right option for you. Upon applying for a generator, many applications will require a specific type of generator to be used and specify if it needs to be enclosed or able to be open. This can raise questions as to why this is required and within this article, we can explain in more detail by discussing the difference between all the options available.


Open-set generators are possibly the main option for customers requiring a large power output from their generator, with the power range of these products being from 6KVA up to 3250KVA for diesel generators, and 10KW 2000KW for gas generators. Generators from our open set range are mainly fitted in prebuilt areas, such as basements, and are used to power various types of buildings such as leisure complexes and hospitals as a backup power supply should their main source of power fail, but some are used for prime power purposes as well. Our open set generators are powered by various well-known brands such as Perkins, Cummins, Mitsubishi, MAN and PowerLink to name a few, and are joined with alternators from Leroy Somer, Stamford and PowerLink.

Canopy Sets

Canopy sets are the most known generators are the main type of generator seen by the public due to them being used a within the construction industry in order to power large construction equipment. This isn’t there only use though, as they can be used as a backup power supply for some properties, due to them being housed within a soundproof canopy so that they can be used in public areas, as well as functioning as a prime power supply in some areas of the world. Fitted with PowerLink, Cummins, Perkins, Kubota, MWM and MAN engines, with Stamford, Leroy Somer and PowerLink alternators, these generators provide a power range of 6KVA to 1000KVA for diesel generators, and 10KW to 1000KW for Gas generators.

Containerised Sets

Containerised generators are used predominantly as a prime power supply, due to the sheer size of the container, and the power output available from these generators. With diesel generators, containerised sets are mainly used to provide power for large buildings such as office buildings or hospitals, but for gas powered generators a lor of customers will opt for a cogeneration unit due to them being able to provide a high power and heat output helping to save money across the domestic bills of the customers. Like the canopy sets, containerised generators are built to house the generators and ensure they are soundproof, which is completed by the containers being heavily fitted with soundproofing technology, and like the open sets can reach a high power output of 3000KVA for diesel and up to 2000KW for gas power.


All in all, the generators aren’t vastly different from one another, but the main thing they all have in common is they are more than capable to satisfy our customers needs. To see all these options for yourself, click on the link for our store below.
