Open frame vs closed frame generator

When choosing a generator, one of the critical decisions you must make is selecting an open or closed frame model. 

Open-frame generators are less expensive due to their simplicity but are also less reliable and potentially more dangerous. Closed-frame generators are more expensive, but they are more reliable and safer.

Before making a purchase, it is crucial to understand the distinctions as each has advantages and disadvantages. So BISON look closer at the differences between these two generators and helps you decide which is best for your needs.

What is an open frame generator?

The open-frame generator is a portable generator with an open-frame design. This means the generator's engine and other critical components are not enclosed in a housing like traditional portable generators. Open-frame generators are becoming increasingly popular due to their many advantages over conventional portable generators.

What is a closed-frame generator?

Closed-frame generators are enclosed in metal enclosures. This makes them more weather-resistant and durable than open-frame models. They are a wonderful option for camping or tailgating because they often create less noise. Closed-frame generators usually have a carrying handle or wheels for easy transport.

Open frame generators vs. Closed frame generators

Size

Open-frame generators are generally more compact and lightweight compared to closed-frame generators. This smaller size is primarily due to their simplified design, which features an exposed engine and fewer protective components. 

In contrast, closed-frame generators are typically larger and heavier because they include protective enclosures and sound-dampening materials. These additional features not only increase the generator's overall dimensions but also add to its weight. 

Noise level

The main difference between open and closed generators is the noise level. Closed-frame generators run much quieter than open-frame generators. 

Open-frame generators are suitable for construction sites, outdoor events, and other situations where noise is not a significant concern. Closed-frame generators are more appropriate for situations where quiet operation is necessary, such as residential areas, campgrounds, and outdoor events where noise levels need to be kept low.

BISON closed-frame generators come with advanced sound insulation materials, providing a quiet operation suitable for residential areas or events where noise is a concern. BISON open-frame generators, though louder, are still engineered to minimize noise while maintaining efficiency.

Engine access

Open frame generators are like conventional generators, with the engine exposed. This makes performing maintenance on open-frame generators easier than on closed-frame generators. While BISON closed-frame generators may require more effort to access the engine, they still provide a user-friendly design for essential maintenance.

Price point

In general, closed-frame generators tend to have higher operating costs. That's because they have more robust frames and tend to be quieter. If you're looking for a simple generator on a budget, an open-frame generator is the better choice. Whether you're on a tight budget or willing to invest in extra features, BISON has a generator that suits your needs and business.

Portability

Open-frame generators are generally smaller and lighter than closed-frame generators. They are much lighter and easy to handle. BISON closed-frame generators, although heavier, come with built-in wheels and handles for easier movement.

Durability

Closed-frame generators are generally more durable than open-frame generators due to their sturdy construction and protective enclosures. These enclosures shield the generator's engine and internal components from damage caused by external factors such as dust, debris, and weather elements. This added protection ensures that closed-frame generators can withstand harsh conditions, making them ideal for long-term use in various environments.

Fuel efficiency

Fuel efficiency varies between open-frame and closed-frame generators. Closed-frame generators usually have larger fuel tanks and advanced engine technology, providing longer run times and better fuel efficiency. Open-frame generators may have smaller fuel tanks and less advanced engines, resulting in shorter run times. However, BISON ensures that both types of generators are designed for optimal fuel efficiency within their respective categories.

Safety features

Closed-frame generators generally come with more safety features than open-frame generators. They often include features such as low oil shutdown, overload protection, and circuit breakers to protect the generator and your appliances. Open-frame generators may have fewer safety features, but BISON incorporates essential safety measures in all their generator models.

Advantages and disadvantages comparison table

Now that you understand the differences between open and closed frame generators, you can decide which type is right for you. If you need a generator that's easy to carry and transport, an open-frame generator is a good choice. However, a closed-frame generator is a better choice if you need a durable and long-running generator.

FAQs

Can you enclose an open-frame generator?

Enclosing a generator in a soundproof box, enclosure, or at the very least a tent is one of the best ways to minimize generator noise. Designed to absorb and deflect sound waves, this enclosure can significantly reduce the noise escaping from the generator.

How loud are open-frame generators?

Conventional portable generators mounted on open steel frames are the loudest, starting at around 69 dBA and going up to 80 dBA, depending on the size and model of the generator.

What is the purpose of the frame in the generator?

The generator frame and casing provide structural protection and support for the inner workings of the generator.
