An open generator or a closed one: What should I choose?

Generators are indispensable units when it comes to autonomous power supply in conditions where there is no electricity. They are used to supply electricity to construction sites, enterprises, country houses, dachas, outdoor events, and many other places. One of the factors to consider when choosing a generator is its performance. In this article, we will look at when it is worth buying a generator in a closed version, and when it is better to choose the classic version on an open frame.

When do I need a closed-circuit generator?

Closed-type generators can be supplied in a container or in a noise-proof casing. This option, "packed" in a special protective case, performs two main functions: reduces noise and protects nodes from aggressive external environment. You should choose this generator option in the following situations:

  • Outdoor installation all year round. If you do not have a separate technical room and the generator will be in the open air, it is recommended to use the generator in a container. It protects the electrical components and the motor from rain, snow and dust. An open model will quickly fail due to corrosion or short circuit when used in this way.
  • Working with people. This is a critical factor for owners of private homes, shops or summer cafes. The casing effectively dampens sound vibrations, reducing the noise level by 15-25 dB. Without it, a working diesel or powerful gasoline unit will make being nearby unbearable, drowning out even a loud conversation.
  • Rent and frequent transportation. For construction crews or rental businesses, the casing or container serves as vandal-proof and shock-proof protection. During loading and transportation, they take the blows upon themselves, keeping the expensive engine and alternator components intact.
  • Extreme weather conditions. When working in rain, snowstorm or with frosts up to -30 °C, the weatherproof casing creates its own microclimate inside. This makes it easier to start the engine in winter and prevents icing of the mechanisms, which cannot be achieved on an open frame without additional shelters.
  • Continuous operation. At facilities where the generator runs for hours or days (construction site, retail outlet, gardening co-op), protection from dust and moisture directly affects the life of the engine. The closed design prolongs the life of the equipment in harsh conditions.

When an open-ended generator is sufficient

An open generator is a classic design where all the components are mounted on a metal frame. Such models are cheaper, lighter and easier to maintain, as
