Air humidification
Water and thus humidity is a natural constituent of the air. Given a room temperature of 20-23°C, relative humidity of 40-55% is ideal for our physical well-being.
To adhere to these humidity conditions throughout the year, air humidification is an indispensable process step within modern AHU systems.
Likewise, adherence to exact humidity conditions is fundamentally important for a large number of industrial manufacturing processes.
Lavair provides the suitable humidifier solution, depending on system-specific parameters like humidification capacity, control accuracy, air speed and installation space.

Air washers
The circulating water spray humidifier, also called an air washer, is a classic among humidification systems. The volume of water atomised within the air flow is several times greater than the water flow required for humidification. The water that is not evaporated is captured in a tank and recirculated to the nozzles.
The air washer remains the first choice for those who require very precise control accuracy in combination with high to very high humidification increases.
Compared to other systems such as steam or high-pressure humidifiers, the air washer is also preferable from an economic and energy standpoint, especially for larger airflows and higher humidification increases.
The cleaning effect of the air is characterised as a positive side effect of the operation. Solid and gaseous compounds like particulates, pollen, spores (allergens) as well as sulphur dioxides, nitrogen oxides and ozone are absorbed to a considerable degree by this. Thus, the air washer is not only used for scrubbing out NH3, but also as an AMC filtration stage in clean rooms for semiconductor production.
Depending on the application, the recirculating water spray humidifier differs in both its technical and constructional design. Our focus is on individual design and adaptation to each customer’s requirements.
The hygienic innocuousness was tested by an independent third-party and confirmed through the issuance of the certificate for compliance with VDI 6022-1.

JETVAP®
High-pressure humidifiers for process air and industrial applications
What continuous-flow water spray humidifiers have in common is that the water volume atomised within the airflow is only slightly greater than the water flow required for the airflow.
The small percentage of unevaporated water is not re-circulated or re-atomised, but is channelled to the wastewater system for discharge.
The humidifier’s injection system therefore constantly operates using fresh water according to the continuous flow principle. The combination of our certified design and the exclusive use of microbially inert materials ensures a continuous hygienic operation.
Our Jetvap® high-pressure humidifiers comply with all current industry standards. Our focus is on ensuring the best possible integration into process air applications.
By using a SIMATIC-S7, a wide-range of customer requirements can be customised or are already fulfilled as part of our patented control concept.
The Jetvap® can be adapted to any system size meaning that it is always a humidifier which exactly meets your requirements. The process reliability, control accuracy and high processing quality have already been proven repeatedly by our international customers. The hygienic innocuousness was tested by an independent third-party and confirmed through the issuance of the certificate for compliance with VDI 6022-1.

JETVAP®-Basic
JETVAP®-Basic
Basic principle
The Jetvap®-Basic high-pressure system is ideal for use as a humidifier, as well as for adiabatic exhaust air cooling, ventilation and air-conditioning systems.
Highly effective evaporation is achieved due to a constant, optimal spray pattern and the use of an microbacterially inert agglomerator.
Due to a user-friendly design, the agglomerator can be reused over the entire lifetime of the humidifier. Chemical additives such as silver ions, biocides or hydrogen peroxide are not required for operation. All water-conducting components are made of non-corrosive materials such as stainless steel, plastic or ceramic, thus guaranteeing the highest quality!
The hygienic innocuousness was tested by an independent third-party and confirmed through the issuance of the certificate for compliance with VDI 6022-1.
Patented controls – Jetvap® – Modulating
The humidification output is controlled by the integrated frequency converter through the use of an output setting of between 0…100%. Our patented Jetvap® – Modulating control concept serves as the basis for this. The required performance can be delivered either via 0…10 V or alternatively via a Modbus. By modulating the pressure range between 30…70 bar, a control accuracy of ± 0.5 % r.H. can be achieved in the performance range of between 10…100%. In the 0-10% range, a clocked mode of operation is used according to the building management system’s required performance, whereby a control accuracy of approx. ± 7% r.H. can be achieved within the partial load range.
