Minimising generator noise with portable generator enclosures

We all are familiar with generators, their types, utility and features. In almost any occasions or to handle special situations we inevitably need a generator that perfectly fits the bill for providing uninterrupted and good power supply essential for the desired purpose. The generator is a wonderful discovery of mankind and the brief science that is involved behind the mechanism of its working is the conversion of chemical energy to electrical energy which is ultimately responsible for the power supply.

Mainly used to serve special occasions, that cannot be held at home and a power supply is necessary, a generator is the perfect answer to meet the demand of the situation. Moreover, sudden power failures are very common nowadays and the generator can be effectively utilised like an inverter to give respite from the troubles of a load shedding.

However while speaking about generators a problem that everyone faces is the rough monotonous noise that comes out of it. It is really something obnoxious and unwanted and may lead to headache if the exposure to noise is prolonged. To find a solution for this, generator enclosures were made, which made good prospects and had wide range of applicability. The portable generator enclosure plans made them more marketable and user friendly. Moreover the problem of having generator and thereby awkward noise was reduced to a more desired level of convenience.

Generator EnclosurePortable Generator Enclosure plans-innovations that guarantee convenience

These type of enclosures for generators have varied advantages, the prime important being the reduction of noise. Moreover they act as a safety device protecting the working of the generator and preventing unauthorised access to it that may prove to be dismal. Children when unattended may find pleasure in having a glance at the machine by casually touching it, which may be fatal. Even this type of problems are also well answered by such type of good enclosures.

Some striking features and portable Generator Enclosure plans are as follows:

a)    The basic idea behind the creation of generator enclosures is perfect insulation. A perfect insulation is the key to safeguard from noise and mishandling.

b)    Another thing kept in mind while its construction is that the enclosure is light in weight and do not add too much to the weight of the generator as a whole.

c)      Since it is portable and light in weight one has minimal problems in handling it.

d)    Lastly the important thing is to select quality material that is strong enough to withstand variable weather conditions without affecting the engineering in any way.

Materials used as enclosures

Generally metals like aluminium is used for the outer casing and special attention is given to its ventilation. Moreover such type of metals are chosen which have durability and less heat retention. More heat retention means more the time taken to cool it down. Lastly ventilation is very important and special attention must be paid to it. Improper ventilation may lead to overheating of the machinery and damage to the product inevitably.

Undoubtedly the portable Generator enclosure plans are wonderful, innovative and creative and meets the demands of mankind perfectly. It goes beyond say that such type of innovation is a big new addition to the gifts of science.



Generator Enclosure A Guarantee For Safety And Durability

If a generator is essential to tide over power outages, so is an enclosure indispensable for it to guard against weather and theft. A generator enclosure comes in various sizes to protect generators of different capacities.

Made of aluminium sheets this generator enclosure is non-inflammable and anti-corrosive, not forming any rust. Typically it is most suitable for housing portable generators of capacities upto 18KW.


Types come based on capacities of portable generators of 7.0KW and below, 8-12 KW, and  10.0 -18.0KW. Space and design features also vary as the sizes vary.

Upto 7.0KW:

Being small, these types have even home-made, improvised generator sheds (or enclosures) made using suncast sheets. However, there are standard scientific design features for enclosures which are to be complied with for overall safety.

Generator Enclosure‘Sine qua nons’ of designs:

a)    Room and enclosure: A Generator Enclosure is a weather-protecting design for maintenance, storage and operation. Size of this ourdoor shed should be 74” L x33” D x34” H. Less noise level and high ventilation other essentials. For this, noise-absorbing panels are inbuilt.

b)    It should have top lift-up and big front door facilitating repairs and airiness with double-lock system in place to ensure safety. Cooling should be ensured for generators using large fans. Large ventilation openings for heat dissipation are some added requirements.

c)    As a precaution against any personal injury, oscillating fans are to be covered with wire cage. Vents with louvers and hoods would be useful for keeping rain water, rodents, birds and insects at bay.

Generator enclosure mounting:

Generator should be mounted on concrete pads or big hard rubber bushes to avoid vibrations and moving.

Conversion of old sheds:

This comes handy as an enclosure particularly for portable generators of 8-12 KW Capacities owing to the metal sheds being generally, sufficiently big in a backyard. They are converted into sheds by suitable additions and modifications.

Extra features:

They include digital carbon monoxide detector and alarm to warn ventilation failures. Judicious fixing of locations for generator, vent locations and exhaust fans in the old shed would make an ideal enclosure, in spite of its oldness. Power cables should be properly negotiated to avoid any hazards.

Enlarged version:

There is an enlarged version with additional features for protecting portable generators of higher capacities 10-18KW with more cooling capability. Dimensions are 112”L  X33” D  X 34  H for this range with sufficient space.

Special additions:

Extra high capacity dual cooling fans positioned on intake and outlets provide the enhanced cooling and circulation. And the hoods with higher air velocity are fitted to reduce rain ingress into the generator compartment.

Electrical fittings:

Transfer switch, panels and sockets for engine plugs and wirings should be placed in a dry, weather –protected place to avoid shocks. High temperature cut -outs for auto stopping should be installed to save generators from excess heat.

Suitability and readiness for use:

This arrangement is suitable for air-cooled, gasoline, diesel, natural gas, or propane fuelled gensets. For liquid-cooled generators, separate arrangements are to be added.

During power outages, it is ready for starting without any dragging or manoeuvring.


Generator Enclosure as a general rule, is not to be installed in residential annexes. Still higher capacity Generators are to be housed in concrete structures with more stringent specifications. The enclosure comes with detailed assembly and installation instructions, which serve as good guidance for standard installation and long life.
