Humidification in the Paper and Printing industry

Constant and consistent control of the HUMIDITY levels in all stages of the paper processing and printing industries is critical for optimum results. To maintain the moisture content of the paper and to ensure proper operation of the equipment, HUMIDITY levels between 40% and 55% are required. 



By maintaining these HUMIDITY levels:

· The paper quality and the finished product are improved

· Dimensional stability of the paper are increased

· Optimum ink transfer

· Less paper jams or breaks

· Reduced paper curl and cracking

· Maintaining maximum equipment speed

· Shrinkage and static electricity are also eliminated


What is the best way to achieve the required HUMIDITY levels?

With the use of Misting SA’s series of speciality MIST nozzles placed in a line around the perimeter of an area, or by using specially designed MISTING rings, attached to box / oscillating fans, when connected to a high pressure MISTING system pump, water is forced through the specialty nozzles and quickly atomized to droplets as small as (5 microns).

When MISTING systems are placed inside an enclosed area (such as a factory), the billions of droplets that are produced will initially provide cooling as the droplets evaporate. However, if the air exchange is limited, the MISTING system will continue to increase the HUMIDITY level within the structure. HUMIDITY levels as high as 90+% are possible. This unique characteristic of all MISTING systems makes them ideal for both cooling and HUMIDIFICATION.
