Inside Noise Reduction for Diesel Generators

Diesel generators are loud, with commercial and industrial generators as small as 1,500kW emitting an astonishing 105 decibels – the same as a jet airplane flying overhead. This noise is a form of pollution and disruption on worksites and, to get the benefits of these durable, economic power generators and deliver the electrical power a site needs while minimizing noise means investing in noise reduction technology. Here’s a guide to why this is so important and how these measures work.

Noise Pollution Standards in Australia 

The EPA in Australia, along with other international bodies like the World Health Organisation have comprehensive industrial guidelines on noise pollution, including community noise and industrial noise prevention. 

According to Safe Work Australia, between 28-32% of the Australian workforce is regularly exposed to loud noise levels at work, with the construction industry as one of the leading industries for noise-related injury. Each year, workers make 4,700 noise-related injury claims across the country. 

The effects of noise from power generators and other loud equipment can have a variety of negative effects, including: 
  • Community disturbance (for example, construction sites within a residential or commercial area) 
  • Hearing loss for employees 
  • Environmental impact on local flora and fauna 
Noise Reduction Technology for Diesel Generators 

Noise reduction technology is designed to let operations access electrical power from diesel generators while making operation as quiet as possible without compromising performance. These measures include: 
  • Built-in noise reduction: Over the years, leading manufacturers like CAT have introduced technology to supply residential, commercial and industrial users with quieter power generation units, reducing noise by as much as 40 decibels to bring it in line with safety standards. 
  • Mufflers and silencers: Mufflers are similar to the technology found in your car engine, helping to reduce noise levels and control emissions, and silencers perform a similar function. Manufacturers offer this technology according to sound rating and grades according to the range of decibels the equipment can reduce. 
  • Diesel generator enclosures: Large-scale commercial and industrial diesel generators are often sold in sound-dampening enclosures to protect nearby people and the environment. It is important to speak to a leading generator supplier to ensure that your enclosure allows for sufficient ventilation to ensure safe, optimal performance of the power generator to ensure a reliable supply of electrical power.

A Guide to Different Types of Commercial and Industrial Fluid Chillers

Fluid chillers in Australia are used in a variety of different industries, including the food and beverage industry, manufacturing, pharmaceutical, and chemical manufacturing sectors. Running on electrical power , this industrial equipment provides critical cooling and temperature control, and utilizing the right type of fluid chiller will optimize productivity, improve efficiency and lower operating costs.  Types of Industrial Fluid Chillers in Australia By Condenser Type   Air-cooled chillers: Air-cooled fluid chillers use the air in the environment around them assisted by fans to remove heat from the refrigerant in the condenser. It then runs the refrigerant back through the system to provide cooling. As a result, the air around these chillers is usually very warm and they are not recommended in applications where this will be an issue. These systems are often portable, available in both large and small-scale commercial versions, are relatively affordable a...

Know the Difference Between kW and kVA When You Hire a Generator

When you want to hire a generator , you’re going to find yourself knee-deep in industry jargon that can make the process a bit confusing. The last thing you want is to hire the wrong diesel generators for your needs, so it’s important to know certain terms in order to make the process easier. Here’s some insight from the CAT rental team. When you ask about diesel generators, the first thing a salesperson will enquire about is the size you require for your commercial or industrial project. Generator size is measured in kilovolt-amperes (kVA), but it’s a term that isn’t well-known outside the industry. Usually, when people hire a generator, they know how much power they need in terms of kilowatts (kW) but not kVA. What is the Difference Between kW and kVA? kW are a unit of real power and a kW rating of diesel generators is how much power they can output based on the horsepower of the engine. Essentially, it is how much power the generator actually has. kVA is a measure of ...
