Air humidification components

The perfect climate for everyone

Hygienically coordinated humidification systems for a wide variety of applications.

Hygienically coordinated system solution

Controlled and optimised humidity is as important as maintaining the right temperature, and not only for human comfort. In industrial environments in particular, it can also affect processing and manufacturing technology. Moreover, dry air has a negative effect on mucus membranes in the human body and makes us more susceptible to viruses and bacteria. Therefore, relative indoor humidity should always be maintained in a range between approx. 40 and 60%.

Furthermore, using adiabatic humidification systems in combination with efficient heat recovery can reduce operating costs.

01. Intake air humidifier

For the most stringent hygiene requirements

Steam humidifiers are deployed in the supply air flow for controlled air humidification. Water is brought to the boil in the humidifier using electricity or gas and evaporates. This separates out or destroys all minerals and biological constituents.
The purified water vapour is injected through the steam lance fitted inside the air handling appliance into the air flow, where it is absorbed. The condensate produced is collected in a stainless steel pan that slopes down to the side drain on three sides.

  • Flawless hygiene
  • Variable output control (optional)
  • Low water losses (condensate)
  • No air reheating required
  • Short installed length possible
  • Easy to service
  • Suitable for various water qualities
