Medium-Pressure Humidifiers

Continuous-flow water spray humidifiers


What continuous-flow water spray humidifiers have in common is that the water quantity atomised within the airflow is only slightly greater than the water flow required for humidification. The small percentage of unevaporated water is not recycled and re-atomised, but is channelled to the waste water system as discharge. The humidifier’s injection system is therefore constantly operated by means of fresh water according to the continuous flow principle. A distinction is drawn between high-pressure, medium-pressure and low-pressure humidifiers based on atomisation pressure.

Medium-pressure humidifiers

  • Pressure range: up to 16 bar
  • Pump type: multi-stage centrifugal pump
  • Nozzle type: swirl nozzle with/without lock function

Equipment variant

  • Water meter for determining the water loss percentage

Application areas for continuous-flow water spray humidifiers, implemented as medium-pressure humidifiers

  • Especially economical in the case of low humidification (0.0 to 4.0 g/kg)
  • From small to large volumes of air (1,000 to 2,000,000 m³/h)
  • Low cleaning overhead required for adherence to hygienic operating conditions
  • Can be supplied either with stainless steel housing or as installation kit for empty housing
  • Pump station with 2 pumps (redundant design)
  • Several humidification systems can be operated via one pump station (master-slave)

Accessories for medium-pressure humidifiers

The medium-pressure humidifier is used in AHU systems which require high hygiene standards. To ensure the operation of the system and to fulfil the hygiene standards, the following components have been selected with the utmost care.

The criteria used for the selection of the components were that they should be PWIS-free, low-maintenance, easy to use and robust.

Control unit

The control unit developed in-house is designed for ultimate flexibility and precise humidification rate. The request for humidity is ensured by means of a synchronised cascade connection. In order to be able to comply with hygiene regulations set out in VDI 6022, the system has an integrated intelligent hygienic flushing program, which ensures that piping is flushed for an existing humidity request without water loss.
