ADIABATIC AIR WASHERS
Air treatment for large volumes in industrial environments
ADIABATIC AIR WASHERS
Adiabatic air washers are the ideal solution for treating large volumes of air in industrial environments where maintaining stable humidity levels is essential. Fully constructed from AISI 304 stainless steel and engineered to deliver high performance under demanding operating conditions, they ensure reliability, long service life, and excellent air treatment quality.
By integrating Aeris adiabatic air washers into your system, you benefit from a high-efficiency technology designed for long-term operation and easy integration with modern air treatment systems. A complete solution that combines high performance, operational simplicity, and energy efficiency.
OPERATING PRINCIPLE OF AIR WASHERS
The operating principle is based on the injection of atomised water into the airflow passing through the air washer. A low-pressure pump delivers water to a series of spray nozzles, which atomise it into fine droplets. These water particles interact with the dry air, which absorbs moisture through evaporation. The process operates adiabatically, without external heat input; the air releases part of its heat to support water evaporation, resulting in a reduction in air temperature and an increase in relative humidity.
Before being supplied to the environment or duct distribution system, the air passes through a droplet separator, which removes excess residual moisture, ensuring a clean and properly conditioned airflow.

FAQ
What is an Industrial Air Washer and how does it improve operational efficiency?
The LVT Series Industrial Air Washers are modular systems specifically engineered to treat large airflow rates ranging from 50,000 to 200,000 m³/h.
Manufactured entirely from stainless steel with anti-fouling engineered thermoplastic internal components, these systems combine air washing, evaporative cooling and adiabatic humidification within a single integrated solution. Compared with conventional humidification systems, the LVT Series delivers outstanding operating efficiency while maintaining exceptionally low pressure losses—only 130 Pa for the standard recirculating-water version and 100 Pa for the high-pressure SAP configuration at the nominal air velocity of 6 m/s.
The reduced pressure drop significantly lowers the energy required by the ventilation system, improving the overall efficiency of the installation.
Which industrial applications are best suited for an Industrial Air Washer?
The LVT Series is ideally suited for industrial processes requiring precise and stable control of indoor temperature and humidity through adiabatic air treatment. The most appropriate configuration depends on the operating environment. The standard recirculating-water Air Washer is recommended for conventional industrial applications where both humidification and air washing are required.
The SAP High-Pressure Air Washer, although particularly suitable for applications where water stagnation must be avoided, is not recommended in facilities where the recirculated air contains significant concentrations of airborne micro-dust. Due to the limited quantity of atomized water used by the high-pressure system, it cannot effectively remove suspended particulate from the recirculated air.
Is there any risk of excessive humidity causing condensation inside the ductwork or damaging production equipment?
The system is designed to supply air with an outlet relative humidity between 95% and 98%.
Before entering the air distribution system, the air passes through the SEP droplet separator module, equipped with high-efficiency PVC blade eliminators that mechanically remove any unevaporated water droplets and prevent moisture carryover into the ductwork.
Because of the system’s exceptionally high saturation efficiency, adjacent technical areas should be properly waterproofed, and a trapped floor drain should be installed immediately downstream of the droplet separator.
How are the water circuit and internal components protected?
The protection of the water circuit is achieved through mechanical filtration and appropriate water treatment rather than biological disinfection systems.
In the standard Air Washer configuration, the pump discharge line incorporates the FTQ automatic self-cleaning filter, equipped with a stainless-steel filter basket that continuously removes suspended impurities.
Collected contaminants are automatically discharged through a timed solenoid valve, protecting the spray nozzles against clogging. In the SAP High-Pressure Air Washer, where the smaller circulating water volume increases mineral concentration, long-term system reliability is ensured by maintaining water hardness above 8–10 °fH (French degrees) with a neutral pH. Depending on the local water quality, treatment may include polyphosphate dosing, demineralization units or magnetic water conditioning systems.
Is the system fully automated or does it require manual operation?
The LVT Series Industrial Air Washers are designed for fully automatic operation and seamless integration with building management and industrial automation systems.
In the standard configuration, humidification capacity can be automatically adjusted either by motorizing the balancing valve with a modulating actuator or by controlling the humidification pump through a Variable Frequency Drive (VFD).
In the SAP High-Pressure version, humidity control is fully digital.
A VFD, directly controlled by the room humidity controller, continuously adjusts the speed of the high-pressure piston pump, modulating the water flow delivered at 70 Bar according to the actual process requirements.
This ensures precise humidity control while minimizing both energy and water consumption.
