High pressure water spray replaces steam - humidifying of process air gets cheaper and more even.

Alongside the existing steam humidifiers Vulganus has taken into use a completely new moisturizing method. The system is based on high pressure water hydraulics and offers several remarkable advantages compared to the traditional steam humidification both in proofing and clean air cooling processes.

In the new system water is lead through small nozzles with high pressure. As water leaves the nozzles it turns into very fine spray and spreads evenly into the cooling or proofing room. Requirements to heat water or add any chemicals no longer exists.

Energy savings are remarkable and it has been estimated that the running cost of steam systems can be as much as 30 times more expensive. Service requirements of a high pressure system is very low due to low temperatures. Stone build-up in boilers, which has been a great problem in the past, will also be eliminated. The only required service is to replace the filters twice a year. There is also no need to do annual inspections of the system.

Investment cost of the new humidifier is low and installation of expensive steam lines can also be avoided. The water hydraulics system is easy and safe to operate due to the fact that there are no hot tubes and steam in the system, which could injure the operators.

The spray humidifier needs very little space and its location can be chosen based on the available space. One unit can also provide moist for more than one spiral system and can also be added to existing processes.
