General Questions

Which system is the best choice for me?

  1. Low-Pressure Misting Systems
    The systems operate between 40 and 100 psi of water pressure. The variance in pressure is because they operate on your household water pressure and not a pump. Normally built with PVC or poly plastic tubing and are connected to a water hose. Typically found on outdoor patios and the misting will get you wet but cool if you are standing nearby.
  2. Mid-Pressure Misting Systems
    The systems operates between 100 and 250 psi of water pressure. A Mid-Pressure Pump is utilized to increase the pressure of the water flow. It is perfectly suited for backyard and patio misting.
  3. High Pressure Misting Systems
    The systems operate between 800 and 1200 psi (pounds per square inch) of water pressure. The systems will work very effectively in both low and high levels of humidity. Even when the humidity exceeds 90%, the effects of the system will be felt with the rapid drop in temperature and make you feel cool and more comfortable. High Pressure Systems create the most BTU's, because the systems produce smaller MIST and creating more cooling evaporation.
    As the micron water droplets flash evaporate they pick up heat from the air, which significantly drops the temperature between 25 and 35 degrees Fahrenheit, without making you wet.

Can you help me?
Yes, of course. Let us help you design the right misting system for you.
Send a email to us with a description, drawings, pictures of the area to be cooled and we'll design a system that's right for you.

I live in a humid climate. Will a misting system work for me?
Yes. The evaporative cooling concept will work any time you are able to achieve evaporation. The more complete the evaporation, the more effective the system will work. For areas with humidity above 80%, temperature reductions will be as high as 10 degrees. For humidity levels between 40% and 80%, temperature reductions will be as high as 20 degrees. Below 40% humidity, the temperature reductions may be as much as 35 degrees.

Will the misting system cause me to get wet?
You will only get wet if you are standing within 6' of the misting nozzle.


Q. 1 What is the water pressure required to create a mist ?
Ans. Minimum 35 Psi water pressure which is a city water supply pressure.
Q. 2 Can I hook this kit with my garden hose directly?
Ans. Yes.
Q. 3 Do they produce a nice amount of moisture?
Ans. Yes, we have four nozzles option for low-high water usage(1.2GPH to 3.26GPH nozzles
Q. 4 Will the fog drop or rise?
Ans. It depends where and how you install.
If you install at the top , fog will fall down. or you can adjust according where the fog required..
Q. 5 Will it be warm or cool?
Ans. Off course cool, mist cooling systems, works on the Flash Evaporative Cooling basics, the fine fog flash evaporates upon contact with heat in the surrounding area, effectively removing unwanted heat and reducing ambient temperature.
Q. 6 How long do they take to start producing a fog?
Ans. Immediately as soon as the misting tubing / pipe filled up with the water.
Q. 7 How can I extend the kit? can it expandable with standard MC552 Patio kit?
Ans. Yes you can extend further easily as many as by 1/2" Extension Kits 10feet mist line MC293
Q. 8 What do I need to buy if I need finer mist?
Ans. Higher the pressure - finer the mist, you can buy our low cost Mid Pressure Booster Pump-380 pressure 160 psi.
Q. 9 What I need to buy ultra fine mist?
Ans. High Pressure Pump module  750 to 1000 psi would produce a real ultra fine mist like clouds
Q. 10 What is the PSI (Pounds per Square Inch) on mid pressure pumps?
Ans We carry two types of Mid pressure pumps.  160PSI and our latest 250PSI pumps. 
Q. 11 How long is the power cord on the pump?
Ans All our pumps come standard with 6ft cord with 3 prongs.
 Q. 12 Is there a limit of nozzles that I can use on each grade
 Ans Yes, each pump has specific flow capcity. Based on that flow capacity, we calculate the number of nozzles that perticular pump can operate without loosing pressure.  Please see our "Misting Pumps" category. We have noted the maximum number of nozzles each pump can operate.
 Q. 13 Can I expand my patio to a tent thats seprate from the patio? And if so what system do I have to have or use?
 Ans Most of our systems are expandable.  You can expand any system to another part of the house or restaurant as long as you do not exceed the pump's nozzle capacity.  For example, if you have a 20 nozzle system installed and your current pump has maximum nozzle capacity of 30. You can easily expand your mist system by additing additional 10 nozzles for the secondary area without affecting the pump performance.
 Q. 14 Can I ever put 2 pumps toghter to make my pressue higher?
 Ans No, this is not recommended and will damage the pumps.  We do manufacture high flow pumps for projects that require large number of nozzles to be operated with single pump.
 Q. 15 Can can combine mosquito and mist cooling system in one?
 Ans No. Mosquito control and mist cooling systems are completely different. There are major variations in Pump, nozzles, tubing and fittings that each system requires.  In addition installation methods and operation times are completely different.  Let's just say that, if it was feasable to combine these systems in one, we would have been selling it by now!
 Q. 16 Can I use a low Pressure pump with High Pressured material/fittings?
 Ans Yes, if the tubing, fitting and nozzles are high pressure rated (1500psi), you can run them with mid pressure pump.  This allows you to upgrade the pump in future while keeping the mist line the same.
 Q. 17 Can I use any cleaning material for my misting system or are there any special chemical to use
 Ans We recommend using our nozzle cleaner to clean the nozzles.  It is proven effective to remove rust and scale. It is also FDA approved and environmentally friendly.
 Q. 18 How far can my nozzles be from the pump to work and does the length of a misting system effect the pressure and quality for the mist
 Ans You can place our mist pump up to 200feet away before installing the 1st nozzle.  This will not affect th pressure.  All nozzles will spray exactly the same on our pump based systems.
 Q. 19 How many brackets can a misting fan support?
 Ans Misting fan comes with wall mounting hardware.
 Q. 20 how can I get left over water to stop coming out of my misting nozzles?
 Ans You can stop the dripping by using our ANTI-DRIP or NON -DRIP nozzles.  These nozzles are available for Mid and High Pressure systems only. Antidrip nozzles will give you "Instant -ON" and "Instant -OFF" effect.
 Q. 21 what is the difference between the stainless steel and the nickel plated?
 Ans Stainless steel nozzles and fittings are made with ALL stainless steel material.  Brass Body and brass fittings have Nickel plated coating on them to help prevent rusting.  Nickel plated nozzles and fittings are the next best thing to Stainless Steel and allows similar functionality without the higher cost of stainless steel.  Our nickel plated nozzles and fittings have passed 100 hour salt misting test and are proven to last in harsh environments.  I.e. coastal areas with high salt content in the air.
 Q. 22 how often should i replace the misting nozzles
 Ans Nozzles will only need to be replaced when they stop misting.  Clogging of the nozzles depends on the quality of the water and filter maintenance.  Poor quality and lack of proper maintenance will clog the nozzles faster.  We offer nozzle cleaning solution and 5 micron filters to increase the life of the nozzles.  We also offer Scale Free Filteration that will prevent the nozzles from clogging due to hard water scale.
 Q. 23 how often should i have my system updated
 Ans Filters should be replaced every 3-6 months on the misting system. If the pump requires oil, it should be changed every 500 hours of run time.
 Q. 24 how should i keep my system safe and working during the winter
 Ans Misting lines should be winterized and pump should be stored indoors to provent freezing during winter months. All water should be drained from the lines, filter and pump.
 Q. 25 can i put any chemical in my misting system to convert it into a misqutio system
 Ans No. Mosquito control and mist cooling systems are completely different. There are major variations in Pump, nozzles, tubing and fittings that each system requires. In addition installation methods and operation times are completely different. Let's just say that, if it was feasable to combine these systems in one, we would have been selling it by now! 
 Q. 26 what is the maxium number of nozzles could i use on a low pressure system and can i place more to get a better misting effect?
 Ans Most of our systems are expandable.  However, on low pressure systems, this depends on the overall pressure available from the water faucet and the total distance.  We found that with standard city water pressure (40-60psi), you can run up to 25 nozzles with about 100ft of tubing before you will experience large pressure and flow reduction.  All our patio kits are made based on extensive pressure and flow test results so that our customers can get the best cooling results. 
 Q. 27 Can i convert a 110v system to 12vDC system when i require?
 Ans This can be done with use of appropriate power inverter.  These power inverters convert 12vdc power in to 110vac. 
 Q. 28 What is the difference between M and MW series Nozzles
 Ans M Series nozzles are Stainless Steel where MW series nozzles have brass body.  MW nozzles have wider spray angle and higher flow rate.
 Q. 29 What nozzles are best for 1000 psi misting system
 Ans To produce the finest possible mist, we recommend use of 0.006'' or 0.008'' orifice nozzles with high pressure systems.  Larger orifice nozzles can also be used if more volume is required. However, doing so may result in larger droplets.
Q. 30 How do i care for my  misting system
Ans See our misting system care page
Technical Questions

What should I do if misting nozzles plug up?
Cleaning Nozzles - Replace or clear obstructed or clogged nozzles.
Nozzles may be cleared by scraping the stainless steel end with flat surface of a knife or screwdriver. To remove nozzle, turn in counter-clockwise direction. Nozzles may be routinely cleaned by soaking in solution of LIME AWAY!" or CLR overnight. Rinse thoroughly after soaking. Replace nozzle by turning in clockwise direction until snug.

Where do I place my patio mist line system?
Place mist line around the perimeter of the area to be cooled. This forms a mist curtain, a cooling barrier between the protected area and the outside heat. The mist line should be mounted 8' to 10' above the ground.

How much water does a misting system actually use?
This will vary depending on the size of the system and the number of nozzles to be used.
You can download the "Nozzle Pump Performance" for more information.

Do I need a filter for my system?
Our high pressure systems are with filters.
For our low and med pressure systems you can use our Poly-Phosphate Filters. The unique Filters actually accomplishes two things. First, it will filter out any sediment from the water supply thereby preventing it from getting into the mist line and plugging the nozzles. Second, the filter contains phosphate crystals which are designed to surround the hard water deposits (calcium, sodium, and magnesium) and prevent them from adhering to the misting nozzle. This will also help eliminate the hard water buildup and will keep the mist system operating at peak performance for a longer period of time.

Is there any maintenance required?
The only maintenance required for a properly designed misting system is a periodic cleaning of the nozzles and an annual check-up for the pump. This check-up may include adding or changing of the oil and tightening or replacing of fan belts (only on the pulley driven pump models), and changing of the filter cartridge. Misting Fan Systems require very little maintenance. We do recommend some preventative care and cleaning for the nozzles.

How many nozzle can I use with the COOLLINE product line. ( High Pressure )
This is depending on the size of the pump and the size of nozzles.
For more informations, you may download the "Nozzle Pump Performance".

How many nozzle can I use with the MIST&COOL product line. ( Low-Med Pressure )

Maximum number of nozzles that can be used
at different water pressures:

1/2 Professional System 3/8" Do-It-Yourself System
Water Pressure Max. # of Nozzles Water Pressure Max. # of Nozzles
25 psi 6 30 psi 6
40 psi 18 40 psi 18
50 psi 30 50 psi 30
70 psi 42 70 psi 46
180 psi 54 90 psi 62
250 psi 58 100 psi 62
    120 psi 106
Our heaviest duty system is designed to work with house pressures and pump aided pressures up to 250 psi. Higher pressures produce more water volume and an even finer mist that evaporates more efficiently. This system is designed for optional installation flexibility and maximum number of nozzles at pressures up to 125 psi. Besides normal patio applications, this system works exceptionally well in greenhouse applications. *Normal house pressures range between 35 psi and 90 psi.
How Many Fans Do I Need?
Each Model 924 and Model 624 High Efficiency Portable Cooler moves approximately 7500 cubic feet (230 cubic meters) of air per minute; this number can be greatly increased where positive pressure ventilation techniques can be employed. Generally speaking, to achieve maximum cooling in indoor or protected areas you will want to transfer the total volume of air in the space being cooled every 1 to 2 minutes.
Indoor Cooling
The appropriate transfer time will depend on the space's insulation, how closed in it is (is it a warehouse or a canopy), prevailing humidity, acceptable humidity increase and the total temperature drop desired.

When cooling indoor areas, it is important to remember that you will need to take advantage of any natural flow of air. You can check for existing ventilation by turning on the mist without the fan on and watch where the mist goes. You will also need to determine your source of outside air and where your outlet for the air is. Very often the outlet will be a door or a window on the opposite side of the structure from the inlet air.
Factory 50' (15 m) length x 80' (25 m) width x 15' (4.7 m) ceilings
Totally enclosed structure with fairly good insulation
Complete air transfer every 2 minutes

Calculation of Volume
Length x Width x Ceiling Height
50' x 80' x 15' = 60,000 cubic feet
Metric Example:
Factory 16 m x 25 m x 4.7 m = 1880 cubic meters (m)
Calculation of Fans Needed=Volume/(Fan VolumexTransfer Time)
60,000 / (7500 cubic feet x 2 minutes) = 4 fans
1880 / (230 cubic meters x 2 minutes) = 4 fans
Four fans will completely transfer the air in this structure every two minutes and should effectively cool this factory. The fans should be placed in the oscillation mode to spread the mist throughout the factory and should be pointed in a direction that keeps the air flow moving in the desired direction.
The ability to cool outdoor areas depends on one major factor - the wind. With either light wind or no wind you can achieve some remarkable results depending on temperature and humidity . Normally speaking in outdoor areas it is advisable to use .012" nozzles. (The exception being areas with extremely highhumidity-60% and above.) Cooling outdoor areas is relatively straight forward and can be broken into 2 different types:
Outdoor Cooling
  1. Athletic and Amusement Cooling
    In this type of cooling, the people don't mind getting damp, and more often then not prefer to. Generally, fans are placed at head height, so people can stand directly in front of the fan.
  2. Factories/Hospitality
    When cooling a large area where the people don't want to notice the moisture. The fan(s) should be set at their highest level with the fan, aimed slightly above the horizon with the oscillation set to match the area being cooled. If possible place the fan 10-20' behind the area to be cooled. This will allow the cooled air to settle and keep the units sound from being bothersome.
