Generator Enclosures: Types & Benefits

Generator enclosures or genTent are mounted a four-wall sounding over generators. They perform a vital function in correlating your business’s portable generator to your electrical system requirements in order to deliver temporary or even long-term electrical power solutions.

This closed protective box meant to protect our generators, switchgear and other equipment safe surrounding unfavorable environment, authenticate sound and ease the work of maintenance and operation.

Strick with this article and you will get to know all the information about types of enclosures, and factors you should consider before buying one.

Types Of GenSet Enclosures

Often categorized by their primary function, Generator enclosures can be broadly classified into 3 types:

●    Weather Protective Enclosures

If you are thinking to install your DG sets outside of your premises. If you are proposing to install a generator set outside your premises. You will need at least a weather protective or weatherproof enclosure. The weather protective Genset canopies are designed to do exactly such to keep the rain and snow out of power equipment.

In-country like India, the climate is extremely hot and humidors in summers and fall up to 0͒ degree in winters. With this extremely changing temperature, we need an enclosure that works well in both kinds of temperatures.

●    Noise Protective Enclosures

While the main consideration when selecting a generator might be focused on fuel type and power rating, but it’s also very important to keep noise levels in mind too. This unwanted noise producing from the generator and other equipment can damage the human eardrum, and many times this damage can be irreversible.

There may be local noise ordinances in place and regulations that enforce a noise limitation that can also strictly adhere to commercial generators.

●    Walk-In Enclosures

The Walk-in Enclosure is a custom enclosure designed for the protection of the generator’s equipment in an outdoor or unfavorable environment. The typical walk-in generator enclosure is a large construction equipped with one or more entry doors (as shown above photo).

These generator canopies can either be full floors or can be an open bottom with wheels attached for home mounting.

Key Factors That You Should Consider Before Buying/Designing A Generator Enclosures

●    Construction Materials

Material is the key!!! It is very important to know what material has been used to make the enclosures you are going to use. Metal sheets(alloy) is a common option for enclosures because it can protect from weather and also be beneficial for soundproofing if the metal itself is the right thickness.

Many instances, powder coating the steel enclosure is an ideal way to reduce corrosion risks, fading of paint, and any damage to the alloy itself.

A secondary option is aluminum enclosures. Aluminum enclosures are best in regions where humidity or high saline ambient air is common. For example, This type of enclosures is beneficial in coastal areas.

A well-designed enclosure should account for the location it is being placed in along with the type and specifications of the generator, and the way it will be used.

●    Fuel

Sometimes it is beneficial to have space for fuel tanks inside the enclosure. The aforementioned allows for better protection and availability of the fuel lines and the connections for power solutions, and hence it results in enhancing security and overall function.

Ensure to choose those enclosures that offer dual-wall construction. Solutions should be put in place to handle accidents including fuel leaks and overflows for better safety.

●    Space Acquisition

When designing for the residential, it’s essential to consider the entire system and how it will be used. This should include service and maintenance needs based on the manufacturer’s requirements. The enclosure should also be expandable to ensure flexibility.

Over time, Genset’s location needs may change or requiring the use of a new generator. In additional cases, a standby generator may be continued at a later date. When configuring the enclosure, assure all of these needs can be met.

●    Ventilation In Enclosure

Generator rooms require a wide variety of fans to optimize the overall performance of generators and other equipment. To avoid heat buildup in the generator room make use of exhaust fans, while supply fans are used to supply fresh air for oxidization and efficient generator performance.

●    Climate

If you are planning to install a generator set outside your building. You will need at least a weather protective or weatherproof enclosure to protect your generator. With the Subtropical humid climate all around the year, choosing one right Genset enclosures can undergo different types of considerations.


So that was the different types of Generator enclosures used to protect Gensets and requirements such as switchgear, control panel for along term use. Choose the one that matches all the climate as well as noise authentic requirements and space too.

If you are a pre owner of a Generator finding an enclosure for it or one who is looking to acquire a Genset, this article will help both to make a good choice of purchasing the one.
