DRAABE, a world-leading manufacturer of humidification systems, announced that high-pressure technology, like its TurboFog system, is increasingly replacing other air humidification systems. “Constant optimum air humidity is the most important climatic parameter for high print quality and trouble free production,” said Wafik Kouchouk, DRAABE’s director of sales. “During the winter months, in particular, air humidity in printing shops often drops to critical levels, thus producing paper warpage, electrostatic charging, restricted machine runability, and production stops that incur avoidable costs frequently associated with an insufficient level of air humidity. Some printing shops allow the air humidity problem to persist while others use a variety of different systems and technologies.” These range from rotary atomizers, steam air humidifiers, ultrasonic atomizers, air washers in A/C systems to compressed air and high-pressure nozzle systems.

Printers need to choose carefully and compare features before installing a humidification system. They must look at their plant, the type of equipment being used, their employee’s health concerns, maintenance and performance of the different air humidification system, and power consumption usage. Making a knowledgeable decision by comparing the various systems on the market is critical.

During the past few years, more and more North American printing shops have converted their air humidification systems to state-of-the-art high-pressure nozzle systems, according to DRAABE. The providers of the different high-pressure nozzle systems can be differentiated by nozzle size, humidity distribution, versatility and services. Systems with extremely fine nozzles exclude any danger of droplet formation and humidity condensation—in particular for low-pressure systems. Maximum and fast distribution of humidity in a room is reached by systems, which have a fan additionally integrated into the atomizer.

DRAABE Humidification manufactures different systems for the printing shop, pre-press, paper store and office areas worldwide. In a high-pressure nozzle system, water is vaporized to a micro-fine degree using a high-pressure pump and special titanium nozzles, which are practically free of noise. In addition, noted Kouchouk, DRAABE’s high pressure nozzle system emits a far greater humidification output from the atomizer than the nozzles used by compressed-air but incurs a fraction of the power costs. “We’re able to supply more humidification in a cost efficient manner,” said Kouchouk. “We’re also able to protect the health of a printer’s plant. The DRAABE water supply is in an enclosed circulatory system. For hygienic and reliable operation only pure, demineralized water is used, which is provided by means of an integrated reverse osmosis system. The pure water produced here can be used optionally as standard process water for printing presses.”
