low pressure humidifier

Flow-through water spray humidifiers have in common that the amount of water atomized within the airflow is only slightly above the water flow required for humidification. The small proportion of water that has not evaporated is not recycled and atomized again, but discharged into the sewage system.

The injection system of the humidifier is therefore always operated with fresh water according to the continuous flow principle. In combination with our ingenious design and the exclusive use of microbially inert materials, a consistently hygienic, flawless operation is thus ensured.

Our low-pressure system Netvap® is specially designed for use with low humidification performance and constant operating conditions. For the most part, this system is therefore used in adiabatic exhaust air cooling, whereby installation in the duct with its own post-evaporation unit is possible, as well as in direct combination with a heat exchanger.

Netvap® can be individually adapted to all system sizes and is always a humidifier exactly according to your needs. The performance can be individually adjusted by the number of installed valve units and optimized to customer requirements. This ensures efficient and cost-effective humidification at all times.
