IHS® AND IHS®Ds EVAPORATIVE COOLERS AND HUMIDIFIERS
Advanced humidification systems
ADVANCED EVAPORATIVE COOLING AND HUMIDIFICATION SYSTEMS FOR INDUSTRIAL APPLICATIONS
IHS® and IHS®Ds systems represent state-of-the-art solutions for industrial air conditioning, humidification, and adiabatic cooling applications. Developed in collaboration with the Politecnico di Milano, they deliver outstanding energy efficiency, hygienic operation, environmental uniformity, and operational reliability, with minimal maintenance requirements.
Both systems are based on an exclusive principle that enables extremely high air saturation levels, ensuring superior performance compared to conventional systems, even in the most demanding production environments.
Their compliance with the strict VDI 6022 standard ensures safe operation in all applications, including environments with high hygienic requirements such as healthcare facilities.
OPERATING PRINCIPLE OF THE IHS® SYSTEM
The IHS® system operates through one or more circular air distribution ducts equipped with precisely engineered perforations along their circumference. The size and positioning of these openings are designed to create an optimal inductive effect, continuously drawing in ambient air and amplifying circulation up to ten times the airflow directly delivered by the fans.
A series of Pulsor diffusers inject finely atomised osmotised water into a laminar airflow. Within approximately two metres, the water is fully evaporated, preventing any droplet formation and ensuring unprecedented air saturation levels, while maintaining a completely dry air distribution system.
Pressure control and system modulation are managed by a stainless steel volumetric pump, designed without valves, mechanical seals, or external lubrication, ensuring maintenance-free operation.
OPERATING PRINCIPLE OF THE IHS®Ds SYSTEM
- Stage 1: Inductive Saturation with Turbulent Flow. This stage is achieved through high-pressure atomising nozzles installed on horizontal manifolds, equipped with shut-off valves to enable multiple humidification stages. Each nozzle generates a vortex effect, inducing rapid mixing between atomised water and process air, increasing the air moisture content to near saturation within less than one metre.
- Stage 2: Evaporative Humidification. The saturated air containing residual micro-droplets passes through a honeycomb PAD post-humidification barrier, accelerating evaporation and achieving saturation levels close to 100% RH. The PAD features a cross-fluted structure that increases contact time and surface area between air and water, promoting natural evaporation. It is manufactured with flocked media to capture residual droplets, significantly reducing water discharge.
- The IHS®Ds system offers up to 15 modulating humidification stages with proportional spray pressure control, ensuring precise humidity regulation with tolerance within ±1% RH.
Additional technical features:
- Supplied with integrated air filtration stages;
- Exclusive use of osmotised water with UV sanitisation;
- Automatic flushing and draining cycles to prevent water stagnation.

APPLICATIONS AND INDUSTRIES
FAQ
What is the IHS system and which industries is it designed for?
IHS (Induction Humidification System) is Aeris Group’s patented adiabatic humidification and cooling technology.
It has been specifically developed for industrial applications in the textile, nonwoven and hygiene industries, where precise temperature and humidity control, together with superior indoor air quality, are essential to ensure consistent production quality and process reliability.
What energy and water savings does IHS offer compared with conventional humidification systems?
IHS delivers exceptional performance while significantly reducing both energy and water consumption.
Compared with conventional humidification technologies, the system can reduce:
• Electrical energy consumption by up to 80%.
• Overall water consumption by up to 65%.
Conventional humidification systems typically require approximately 4 kWh of electrical energy to evaporate a given volume of water.
For the same humidification capacity, IHS requires only approximately 1 kWh, providing a substantial reduction in operating costs while maintaining identical process conditions.
What do the values "COPH >40" and "SEH 100%" mean?
A COPH (Coefficient of Performance for Humidification) greater than 40 indicates that the system delivers more than forty times the humidification effect compared with the electrical energy consumed.
A 100% SEH (Saturation Efficiency for Humidification) means that all the water introduced into the air stream is completely absorbed within approximately one metre of the discharge point.
As a result, there is no wastewater discharge, maximizing both water efficiency and hygienic performance.
What is VDI 6022 compliance and why is it an important advantage of the IHS system?
The IHS system has been designed in accordance with the hygienic principles of VDI 6022, one of the world’s leading standards for hygiene in ventilation and air humidification systems.
Compliance with VDI 6022 helps prevent bacterial growth, mould formation and microbial contamination within the humidification system, ensuring healthy indoor air quality for operators while minimizing hygiene-related risks within the production environment.
How does the IHS system support Industry 4.0 requirements?
The entire system is managed by DIGITRON 2.0 Vario, Aeris Group’s proprietary automation platform.
Using an open Modbus communication architecture, the control system integrates all field sensors, motors and actuators into a single intelligent platform. Advanced predictive control algorithms continuously analyse both indoor and outdoor operating conditions, automatically regulating airflow and water flow to achieve maximum energy efficiency. The platform also includes native remote monitoring, data logging and energy reporting functions, allowing plant managers to supervise system performance remotely from PCs, tablets or smartphones.
