A soundproof generator, soundproof container, or silent generator are terms that many people are familiar with. Few people, though, are aware of how they operate or what to anticipate from them unless they are employed in the field. The operation of a soundproof container Generators are very noisy, particularly those that are not containerized. They are so loud that working close to them can result in hearing loss unless protective gear is worn, and they are so noisy that they pose a serious risk to surrounding businesses and bystanders. Therefore, to ensure that any portable or emergency power generators only produce an acceptable level of noise, laws and regulations have been passed. A silent generator reduces noise that is audible to customers, staff, and other members of the public by operating inside a soundproof container or generator enclosure. What a soundproof Generator Enclosure contains? The majority of silent generators or soundproof containers are made of composite materials in their generator enclosures. Usually, there are two types of materials used for this purpose: hard layers that reflect sound energy into the enclosure and soft, porous, resilient layers that absorb sound energy and turn it into heat. However, different materials absorb different frequencies more or less effectively. It's possible that "Material A" absorbs very high frequencies very well but poorly at lower ones. "Material B" may be excellent at absorbing low to midrange frequencies, but it is ineffective at high frequencies. For this reason, the majority of contemporary soundproof generators employ multiple layers of various materials. Highly porous materials work best at absorbing higher-frequency sound because they can send these smaller waves deep into the material, dispersing and absorbing them. The challenge of lower-frequency sound is completely different. Sometimes, large, heavy layers of material that are merely resistant to movement can deflect or absorb these waves; however, when working with lightweight materials, an "air pocket" technique yields the best results. Large, shallow air gaps separate the thin material panels. This arrangement raises the low-frequency sound to a higher, sharper pitch by using the resonance effect. The porous materials in the air gap itself can then absorb that higher-frequency sound. Since not all generators produce the same frequency range, the specific materials and layering techniques used will vary depending on the generator. For the soundproof container to be as effective as possible at absorbing the precise range of sound that the gen-set produces, a generator enclosure should be engineered for a specific class and type of generator, or better yet, a specific model. GENERATOR NOISE - HOW IS IT QUANTIFIED?  Decibels (dB) are commonly used to measure sound levels. Loud is generally defined as anything over 80 dB. Most people find sound levels between 100 and 125 dB to be "uncomfortable," and beyond 140 dB, most people experience pain. There are two ways to measure the noise produced by a generator: either on an audible scale (dB(A) that only really considers sounds that human ears can normally detect, or on a linear scale (dB(L) that weights all frequencies equally. dB(A) is the most useful scale to use for a soundproof container

The Metal-halide Towers are expensive to maintain to start with. They go through as many as 10 bulbs and ballasts replacement per year. They are sensitive and can easily got damage during transportation. As lighting towers are usually required in a remote areas the cost of bulbs and ballast is not the main concern for the customer but also the cost of call out that cover labor hours, travelling to site and service expenses. An additional cost to consider is that the Metal Halide bulbs consume more fuel and require an over-sized alternator to supply 4000 W required to emit light. On the operational side a major disadvantage of Metal Halide bulbs is they re-strike and need few minutes warming time before they lit again once they are shut down. Metal-halide bulbs light efficiency also erodes with time and have a short running life expectancy comparing to LED bulbs that can run for 50000 hours. The LED lighting technology on the other hand are highly efficient, have a longer running life, less downtime, no ballast required, durable, can be configured to reduce glare, better light quality, require less fuel, no re-strike issues and they far exceeds the light output of the traditional Metal halide light. On the top of that the LED Light heads can be environmental friendly as they can run on solar system only at zero emission, zero noise, zero pollution. For the above reasons GET have all type of vertical, solar, portable LED Lighting Towers available in stock to serve and light your business needs.

Diesel engines are the workhorses of power generation, agriculture, construction, drilling, forestry, industry, mining, transportation and shipping. They power everything from generators, buses and combines to bulldozers, excavators, semi-trailer trucks, ships and trains. Diesel powered engines are classified as internal combustion engines. chemical energy is converted into mechanical energy. This occurs when fuel is channeled into the interior of the engine where it ignites to produce energy that’s converted into power to make a machine move or produce electrical power. Diesel engines feature a compression ignition (CI) system that in very basic terms produces combustion using: Super-heated air. Air is pumped into a compact cylinder where it’s quickly and forcefully compressed by the piston. This rapid, powerful compression causes the air to instantly heat to a high temperature, typically between 500 and 1000 degrees F. Fuel injection. A fine mist of fuel is injected (sprayed) into the cylinder, where the super-heated air causes it to instantaneously ignite without the need for a spark plug or other fire source. Energy. When the air ignites, it produces energy that pushes the piston out of the cylinder. This transfers power from the cylinder to the piston, through the crankshaft and gears to turn the wheels and make your vehicle go. When a diesel engine is running, the CI process is repeated over and over again producing the steady stream of energy required to power machines. Diesel engines offer significant advantages. The fundamental design is simpler and more straightforward, comparatively speaking, so there are fewer parts to maintain or replace. The compression process is forceful and effective, which burns fuel more completely and produces more energy to make the most of every drop. This effect is maximized because diesel fuel is denser than gasoline, so each gallon produces roughly 30% more energy on average. The dense fuel also acts as a better lubricant, which reduces friction and helps diesel engines last longer. Diesel engines also have a few drawbacks. They perform best at the steady speeds required for highways, but can seem sluggish in stop-start city driving. Because diesel fuel is less refined, it contains more energy potential but produces more emissions, so in spite of improvements, many diesel-powered vehicles continue to fall short of their gas-powered counterparts.
