General Questions and Expert Answers


In Australia, the misting system industry is a small, specialty business. Many companies dabble in the industry, but few have the resolve, knowledge and dedication to stick around for the long-term. The best method of sourcing a misting expert is to rely on longevity and experience. 

CoolMist Systems Australia has been providing high quality systems for residential, commercial and industrial applications since 2005. Aligned with European manufacturers who use only the highest quality components in the manufacturing of our products, we bring over 30 years combined industry experience. There are few competitors that have the level of experience or understanding that is provided with every system designed and sold by CoolMist Systems Australia. 


The principle behind effective dust suppression is to deliver water droplets similar in size to that of the fugitive dust particle. Water droplets that are too large deflect the dust particle leaving the dust air-borne. 

CoolMist® high-pressure systems operate at 1000 psi to maintain a strong steady pressure which is required to produce atomised water droplets sized 5 -10 microns. Billions of micro-fine water droplets similar in size to the dust particles are dispersed to engulf the dust cloud. These then combine with the minute dust particles and together they fall to the ground leaving the air dust free.


Not all misting systems are the same and rarely does a one size fits all approach suit every application. Your system should be designed to your specific environment. This includes the type of pump needed, water treatment, the distribution system, line or fans, and the nozzles. These key factors when combined properly work together to provide you with a system that does the job that is right for you. 

One of the most important components of a misting system is the misting pump used to drive the system. Don't be misled in thinking that all mist system pumps are the same. CoolMist Systems Australia has a range of high-pressure misting and fog system pumps that consist of high quality components and innovative control options to produce the desired misting effect for your project. When deciding on which high-pressure pump system is best for you, consider the size of the area, the mist effect you wish to achieve and the time it is required to be in use. 

CoolMist Systems Australia design systems that are tailored to your specific environment. With over 30 years combined industry experience in high-pressure misting systems we'll work with you to provide an effective and efficient system that you can rely on.

Misting systems use "flash evaporation" to provide excellent cooling, humidification or dust suppression for domestic, commercial and industrial applications. Equipment is custom designed to suit each individual application. 

The system comprises of a high-pressure pump module, distribution tubing, and misting lines constructed of stainless or polyamide tubing, or stainless steel rings fitted to the front of industrial fans. 

Normal mains water is pressurized to 1000 psi and then forced through specially designed nozzles. This results in water being atomised into millions of water droplets. The droplets flash evaporate cooling the air or absorb the dust cleaning the air.


Inexpensive misting systems are built for price and price only. They were not built to last long and are made from the cheapest foreign components. 

We are highly selective of our suppliers for the components that make up our misting systems. All components are manufactured to the highest industry standards using high quality materials., and therefore as the saying goes,"You get what you paid for". 

This means CoolMist® misting systems will last a long time and provide you with the highest quality misting solution possible.


High pressure misting systems offer significant advantages over mid and low pressure systems. Although they are higher priced the benefits that they offer outweigh the costs. 

Advantages include water droplets that are of a smaller size resulting in better evaporation of water and therefore more effective cooling of the environment. It also results in more effective dust suppression. High pressure systems are also more efficient in larger areas as the water pressure throughout the whole system will be consistent resulting in the benefits being applied throughout the whole area. 

A low pressure system requires nozzles with larger outlets resulting in larger water droplets. This results in less effective cooling of the environment, a lower level of dust suppression as well as potential water residue over the affected areas.


Misting systems and fog systems are used interchangeably when talking about a high-pressure system. Simply put, these two terms describe the same type of high-pressure misting system that is used to create a fog-like effect. 

Depending on the solution you require our high-pressure misting systems are used throughout Australia to regulate the environment by cooling the temperature, cleaning the air of air-borne dust, providing precise humidification and neutralising offensive odours.

The old adage "you get what you pay for" is very appropriate when considering a high-pressure mist system. Of course, all mist systems have a nice cooling effect in areas under heat duress, i.e. the temperature is reduced to some degree. However, high-pressure mist systems offer significant advantages over mid and low pressure systems. 

One of the main advantages of high-pressure mist is that it does not lose pressure over long line runs or with lines of many nozzles.The same spray pattern is present at the beginning and the end of the line. Low and mid systems struggle and lose uniform spray when there are more than 25 nozzles or when there is use of 90 degree bends in the water line. 

CoolMist Systems will design the system that will give you the best outcome for your cooling project.


YES! Absolutely! In higher humidity areas like Queensland, North Western Australia and the Northern Territory we recommend high-pressure mist systems for the best cooling. You can expect an 8-10 degree drop in temperature using mist lines, and up to a 15 degree drop when using mist fans. Our highest measured temperature decrease to date is 17 degrees Celsius in a fruit packing shed located in Carnarvon, WA where packers were working in an extreme environment.

Dust Suppression FAQs


Dust consists of tiny particles of dry, solid matter. Industrial dust is a by-product of activities such as earthworks, excavation, blasting, transportation, product processing, manufacturing and waste and recycling processes. Dry climatic conditions and wind can intensify dust generation.

Dust has a significant health and environmental impact associated within many areas including mining, construction, demolition, manufacturing, and agriculture industries.

Many operators are challenged daily as dust particles pose serious health issues, increased maintenance cost and down times, loss of material, product quality and reduced productivity and regulatory compliance.

Without proper dust control, your workers are exposed to harmful dust, particulates, and contaminants in the air. Airborne dust particles cause breathing difficulties, skin and eye irritation, and serious respiratory diseases. Prolonged exposure to these dust particles can significantly affect the health and well-being of your workforce.

Dust can damage and interfere with the functionality of equipment like conveyors and their components, plant and equipment, motors, and machinery. Constant exposure to dust can result in frequent and unscheduled shutdowns and increasing clean-up costs.

When dust escapes beyond site boundaries, it can have a negative impact on near-by properties and eco-systems.

By having proper dust control measures onsite, you can improve operations with continuous productivity, a safer, healthier, and cleaner workplace for employees and meet OH&S and environmental obligations.


CoolMist Systems Australia supplies dust suppression systems for indoor and outdoor applications. Finding the right dust suppression solution for your workplace may be as simple as a fogging system installed at the dust source or you may require a larger system installed to run a number of zones.

Static line misting systems use high pressure (70bar, 1,000 psi) pumps to atomise water into microscopic droplets to limit the dispersion of fine dust particles. A network of strategically placed misting nozzles emit the fine spray of micron-sized water droplets that absorb the dust particles in the air. The increased weight of the dust particles causes them to fall back down to the ground or to the process material and remain there, leaving the air dust-free. Utilising this method of dust suppression can greatly inhibit dust from circulating throughout the entire facility.

Additionally, mist fans fixed to walls or 360 mist fans suspended from the ceiling can be considered as effective dust suppression tools.

Mist cannons - also recognised as fog cannons, dust cannons, fog makers, spray cannons - are used for dust suppression in many work processes in quarry operations, mine sites, demolition and construction sites.

AJet® Mist Cannons propel atomised mist with a high velocity fan over large areas. CoolMist® mist cannons throw fog from 15 to 150 metres, which makes them a powerful and effective solution for dust control. Water flow rates can be adjusted to regulate the volume of water discharged from the mist cannon to control both surface dust and airborne dust without saturation problems. The cannons can be setup in a fixed or mobile position depending on your specific needs.

A professionally designed and installed dust suppression misting system can remove dust particles from 0.1 to 1000 microns reducing PM10 dust levels and assist compliance with EPA dust control standards. Our team will assess the site and dust intensity, matching water droplet size to corresponding dust particle size. Based on your requirements we will tailor a dust control system designed to work effectively and efficiently.


To maximise the potential of dust capture by water dust suppression systems, the water droplets need to be similar in size to that of the dust particles. Water droplets that are too large deflect the dust particle away leaving the dust air borne. The mist density (fog cloud) also needs to be greater than the concentrations of dust in the air so that all the dust can be captured.

Our misting systems and mist cannons operate on the principle of binding dust using tiny water droplets similar in size to the dust particles. CoolMist® misting systems and mist cannons effectively break down PM10 and smaller suspended dust particles by using water droplets similar in size to the dust particles.

Tiny, atomised water droplets, 10 microns, form a dense fog and trap the dust particles increasing their weight which causes them to fall from the air. Particles from 0.1 to 1000 microns have little chance to escape and are quickly arrested, removing dust from the air.

The low volume of water emitted from our systems avoids residual problems such as pooling or oversaturation and achieves dust suppression with maximum efficiency at sustainable water usage rates.

Cooling FAQs

Humidification and Climate Control FAQs


CoolMist® fresh produce misting systems use only fresh water, no chemicals, no additives.


The spray from our produce misting system is from fresh potable water. We do not recommend using stagnant water from storage tanks. 


Cut fruits and vegetables wilt and lose moisture. They are no longer connected to their roots and cannot absorb water and dry out and rot more quickly. Misting systems deliver a fine layer of water to the surface of the vegetable, and keep a humid environment on the display shelves. The misting system targets the section of refrigerated produce efficiently keeping produce fresher for longer without affecting the other products in the grocery store.

Odour Control FAQs

Landscape and Themed Fog Effects FAQs


Effects for landscape, creative and theatrical themes commonly use artificial fog or smoke machines. To create the special effect, these machines use chemical or oil-based substances to reproduce synthetic mist.

CoolMist® create special effects with water in place of chemically based products. Our high-pressure systems offer a safe alternative and produce a natural fog on demand to highlight and create an interesting and visual display.

Our special effects misting, and fogging systems are tailored and built specific to your project.
