Generator Covers

Generator covers are necessary for construction, manufacturing, and mining, where generators might be in use. They are also used in public areas near a source of frequent power surges or exposed to hues that can damage them. Moreover, they can protect generator exhausts and help stop sparks from flying away. While most generators have their cover, some require additional equipment or other forms of protection for optimal safety and security against theft.

Types of generator covers

The generator tent often is overlooked, but it is an essential accessory. It’s critical to choose the right one so that it protects the generator without hindering its operation.

There are two types of generator covers:

  • Storage covers, which are for protecting the generator when it’s not in use.
  • Operational covers, which preserve the generator while it’s running.

You can’t go wrong with either storage or operational covers designed for open-frame generators or closed-frame generators. Closed-frame generators have housing surrounding the generator motor and other internal workings, whereas an open-frame generator’s internal parts are exposed to the elements.

Open-frame covers

Open frames are good at cooling down the generator and around it. They act as a buffer between the generator and external interruptions or hues. They are also ideal for open-passage areas too. The open frame is easy to install but not as rust-resistant or long-lasting as other types of covers. These types of covers are fundamental in public areas that might be affected by hues from the surrounding areas around them.

Closed-frame covers

These are finely made and are highly resistant to rust. They feature a completely enclosed design making them resistant to the elements and even dust. They can be easily found online if you want to buy them for your generator.

Weatherproof cover

The most common type of cover used on both open- and closed-frame generators is the standard weatherproof cover. These covers usually consist of four panels: top, bottom, front, and back. The top panel has vents so that air can flow through the cover during normal operations. This allows heat generated by the engine to escape as well as allowing cool outside air into the interior of the unit – a gasket seals around the perimeter of the opening between the top and bottom panels.

Vented Cover

The second type of cover is called a “vented” cover. Venting helps prevent moisture from entering the generator enclosure. It also provides more ventilation than a non-vented cover. Vented covers typically include three panels: top, middle, and bottom. They’re often made out of aluminum because they provide better protection against corrosion than steel.

Ventilated covers may be single-piece units or multi-piece units. Single-piece ventilated covers are constructed entirely of metal and feature an integral frame. Multi-piece ventilated covers are composed of several pieces, including a base plate, sidewalls, and end caps. Both styles offer excellent protection against rain, snow, and wind damage. However, if you live where there is heavy precipitation year-round, then a vented cover might be your best bet.

Plastic Cover

Another option is a plastic cover. Plastic covers are available in many different shapes and sizes. Most generators are compatible with plastic covers, although some have specific dimensions that impede machine-type covers.

Hinged Covers

Hinged covers are very easy to install and remove. They can last longer than the hinges and pivot points used to make them functional. The hinged ones can be opened, using the hinges, to a 45-degree angle and then be folded to form a manageable rectangle. Hinges are prone to rust but can still last for several years even while exposed directly to the elements.

Sliding Covers

These covers are very easy to install but rely on keeping the generator panel in place. There are no hinges or fasteners used. It can be locked into place or rolled down when not in use. They are usually made to cover all three panels instead of only the front panel. The sliding type is great if you want a maximum security cover since it protects against theft and tampering with panel covers and switches.

Some generators require additional equipment or other forms of protection for optimal safety & protection against theft. Gas-powered generators have exhaust vents that need to be removed before they can be protected with a standard cover. A “windscreen” is added to the back of the generator cover for this purpose.
