What sized Mist Maker do I need?
Choosing the right size Mist Maker depends on a few different things. Ambient humidity, target humidity, air exchange, and the type of material your room is constructed of all plays a part.
A lower ambient humidity will increase the need for more discs, as well as a higher target humidity. The amount of air exchange you have will play the biggest part in deciding which size you need. If you are constantly bringing in new air, you have to work much harder to bring up the humidity. Rooms constructed of concrete tend to absorb moisture for quite some time before leveling out. This can increase your need for a bigger Mist Maker as well.
With low air exchange, a smaller unit can be used. It may take longer to reach your target humidity level, but as long as drier areas not being introduced to the room, a smaller unit will suffice.
With that said, I typically recommend a larger unit such as a 6 to 12 disc Mist Maker for larger rooms, Shipping containers, and green houses. It is better to have a capable unit that runs much less, than a inadequate unit that has to run 24/7. Mist Maker's heat the water that they are operating in, and heat can damage electronics. Very long run times in small reservoirs can push the max operating water temperature of 105°F.
There are different options for controlling the output of your Mist Maker. We offer fog output controllers, as well as humidistats. Humidistat will automatically control your humidity within 3% of your target level. The machine automatically turns The Mist Maker's power on and off when needed.
For humidification, it is recommended that you use our 120 mm, fully encased, waterproof fan in order to efficiently push the fog out into the room. Our smaller 80 mm fan is geared towards small applications.
