|High vs Low Pressure Misting Systems
|If you have been looking to install a misting system on your patio to keep you cool this summer, chances are you
have come across the different types of misting systems that are available to you. There are low pressure,
medium pressure, and high pressure misting systems available.
Which of these misting systems is best for you? Which is the most effective for mist cooling? We know it can be
confusing to decide what type of misting system you should get, so we put this page together to help you decide if
a high or low pressure misting system would be best for your needs.

High Pressure Misting Systems
If your budget allows, we highly recommend installing a high pressure misting system. You will not regret it between the bold
fogging effect it gives you and the cooling relief it provides! High pressure misting systems are the most efficient misting systems available.
A high pressure misting system can lower the real feel temperature by as much as 35ºF. As with any misting system, the lower your humidity, the
more efficient the misting system becomes. Since the misting system uses high pressure water, almost all of the water that exits the nozzles
evaporates instantly. For the most part this prevents you from getting wet, which can happen with low pressure misting systems. It is important to
realize that in moderate to high humidity areas not all of the mist from a high pressure misting system will evaporate, but more mist will evaporate
compared to a low pressure misting system. High pressure misting systems are fairly common at restaurants, hotels, and homes in the desert. High
pressure misting systems can also be used to achieve a fogging effect for decorative purposes.
A high pressure misting system is the most expensive type of misting system. The misting system consists of a high pressure misting pump and high
pressure supply line with misting nozzles. The supply line on most high pressure misting systems consists of high pressure Nylon tubing or stainless
steel tubing. The supply line then spans the entire length of your patio or deck to line the entire area with misting nozzles. By lining the entire area
with misting nozzles, you can cool the area down faster.
High pressure misting pumps are available in a variety of pressures and flow rates. A high pressure misting system typically runs anywhere from
1000 to 1500psi. The flow rate on the misting pump can vary widely from 1.0gpm to 3.0gpm or more. Basically the more misting nozzles you have on
your misting system, the more gpm your misting pump has to flow. Most misting pumps come with adjustable regulators that allow you to increase or
decrease the pressure or flow rate of the misting pump.
A high pressure misting system cools the air the best because it utilizes high pressure water from the misting pump. The higher the water pressure,
the finer the droplets of water that come out of the misting nozzles. The fine water droplets make it easy for the mist to "flash evaporate" into the
surrounding air. The more mist your misting system can evaporate into the air, the cooler the surrounding air will feel!
Low Pressure Misting Systems
First let us start out by saying that no matter what you have been told in the past, you will not get "soaking wet" from a low pressure misting system.
The exception to this is if you buy a misting system that uses cheap misting nozzles that produce large water droplets and not fine water droplets
like our misting nozzles. While it is true more mist evaporates from a high pressure misting system, the mist is very fine from a low pressure misting
system and it will not drench your clothes, body, or patio table with puddles of water. Most people actually comment that the fine mist that doesn't
evaporate from a low pressure misting system feels quite good on a hot summer day. We would have to agree ourselves!
Low pressure misting systems run off any standard garden hose utilizing normal household water pressure. Generally speaking any misting system
operating at less than 100psi is classified as a low pressure misting system. Low pressure misting systems can cool the outside air by as much as
20ºF. As with any misting system the lower your humidity the more efficient the misting system becomes. Low pressure misting systems are a great
alternative for someone who doesn't want to make an investment in a high pressure misting system.
The supply line of a low pressure misting system is typically made from PVC piping or Nylon tubing. The supply line then spans the entire length of
your patio or deck to line the entire area with misting nozzles. By lining the entire area with misting nozzles, you can cool the area down faster. Low
pressure misting systems are also common for dust and odor control applications due to their low cost and are usually very effective in most cases.
A low pressure misting system will not produce a fogging effect like a high pressure misting system and are recommend if you don't want "fog".
