1- How much is the cooling efficiency of a high-pressure misting system?
Cooling efficiency of a misting system depends on relative humidity, the lower the humidity, the greater the temperature reduction.
• At below 40% relative humidity, temperature reduction can be around 10°C
• At 55% relative humidity, temperature reduction is approximately 7°C
• At 70% relative humidity, temperature reduction may be around 4°C
This is why misting systems perform best in dry and semi-dry climatic conditions.
2- Where is misting more effective, indoors or outdoors?
High-pressure misting is equally effective for both, however mid-pressure misting is suitable only for outdoor use only.
3- Are misting systems effective in humid season?
High-pressure misting systems are effective in humid season as well, but the cooling impact is comparably lower than what you will experience in the dry season.
for example: At humidity 70% – 80%, maximum heat reduction may be 3C.
While at 40% – 50% maximum heat reduction may be 8C.
4- Does misting system cause dampness
High-pressure misting systems produce ultra fine fog that evaporates instantly without causing dampness. The use of on/off timer should well be appropriate.
5- Are misting systems safe for make-up, wood, paint & Electrical appliances?
A properly installed & operated high-pressure misting system is absolutely safe, because nothing gets wet.
6- Is misting harmful for plants, pets and humans?
Misting is blessing for plants, pets and human health. It helps respiratory system, just like nebulisation, ensures fast recovery against flu, cough, Asthma and dust / pollen allergies. Also keeps plant really fresh & healthy.
7- Do misting systems require maintenance?
Misting systems should be serviced at the start of each summer season. During the operating season, periodic cleaning of stainless steel filters or replacement of polypropylene filters is required, depending on water quality. Pump oil should be replaced every 250 hours of operation. In addition, nozzles may require occasional cleaning, again depending on water quality.
8- Can saltish water be used for misting systems?
Saltish water means higher TDS content, which may clog nozzles more frequently and produce uneven mist. Drinking quality water with TDS level below 350 ppm is pre-requisite for misting.
9- Can saltish water be treated?
A reverse osmosis (RO) plant can be used for water desalination. Various capacity RO plants are available manufactured at the bases of water consumption, initial TDS level and final TDS requirement.
10- Do we need to replace misting nozzles, when clogged?
Clogged nozzles can be cleaned by dipping their heads in concentrated acetic acid for 10 min. The process is easy and can be performed multiple times without damage.
11- How much water does a misting system consume in one hour?
Water consumption varies, depending upon weather conditions, pump size & number of nozzles applied. More water will be consumed in hot & dry season. For example: 1L/min capacity misting pump may consume approx. 10L/H in moderate season, on contrary 45L/H in dry season.
12- How much is the service life for a misting system?
Amongst three types of misting, high pressure (HP) is most robust, followed by mid-pressure (MP) misting & low pressure systems are most fragile.
Life varies for various parts, oil lubricated high-pressure plunger pump can last for 8-10 years if maintained properly & serviceable parts replaced in time. While mid-pressure pump may last for 3-4 years under proper use. MP Nozzles need replacement earlier than HP nozzle. HP & MP tubes are rarely replaced if installed indoors, for outdoor use they may last for 6 & 4 years, respectively. Similarly, HP accessories last longer than MP accessories.
13- What sequence should be set at the misting system timer?
Begin with 5 seconds ON and 15 seconds OFF.
Gradually increase the ON time (for example, 8, 12, or 15 seconds) if greater cooling is required, and reduce it if less cooling is needed.
The OFF time can also be adjusted:
• Increase OFF time to reduce excessive fogging
• Decrease OFF time to increase mist density
An effective cooling result comes from maintaining a balanced combination of ON and OFF times. Please note that timer settings may need periodic readjustment to suit changing weather conditions.
14- What is Mist?
Fine water droplets averaging 25-50 micron in size are termed as mist, often confused with fog, which is technically much more finner than mist. One can produce mist artificially through a mid-pressure misting system that operates at 150-200 PSI. Mist can float in the air for 15 seconds, after which it either evaporates or falls to the ground.
15- What is Fog?
Very fine water droplets averaging 8-15 micron in size is termed as fog. It can be produced artifically, through a high-pressure misting system that operates at 800-1000 PSI. Fog can float in the air for 40 seconds, after which it evaporates completely.
16- What is Spray and Rain?
Course water droplets with average size 100-300 micron and above are termed as spray or rain. Which can be produced artificially through a low-pressure misting system that operates at 20-60 PSI. Spray and rain droplets are effective for bathing cows & birds, drip irrigation and for spraying pesticides & disinfectants. You cannot expect spray to work like mist and fog.
17- What do GPM and LPM stand for?
GPM stands for gallon per minute. It is a unit of measurement of water flow rate in gallons in period of one minute.
LPM stands for litter per minute. It is a unit of measurement of water flow rate in litters in a period of one minute.
18- What is the difference between PSI, MPa, KPa and Bar?
These are units of measurement of pressure, i.e., the force with which the water is pumped by a misting system.
PSI stands for pounds per square inch.
MPa stands for megapascal
KPa stands for kilopascal.
1bar=14.504PSI=100KPa=0.1MPa.
1MPa=145PSI
19- How do misting suppresses dust & Pollen?
High-pressure misting systems generate millions of ultra-fine fog droplets, typically 10–15 microns in size. These microscopic droplets provide a large surface area that attracts and binds with dust and pollen particles, making them heavier and preventing them from staying airborne.
As a result, misting systems naturally reduce airborne dust and pollen, helping to purify the air in a natural way.
20- How much Electricity does a Misting System consume?
Misting systems are highly energy-efficient. On average, they consume approximately 0.15 kWh to cool a 1,500 sq. ft. outdoor area and about 0.4 kWh for a 3,000 sq. ft. outdoor area.
For a 3,000 sq. ft. indoor area, electricity consumption can be as low as 0.15 kWh, which is up to 50 times less than the energy required by conventional air-conditioning systems.
21- Can I install misting system myself?
Installation of a misting system looks straight forward, practically it is entirely opposite. There is no short cut to competency, installation requires skills & experience otherwise misting can become a nightmare. Therefore we do not recommend DIY.
