The programmable solution for efficient control ofAir Handling Units and Systems
2
Air Handling SystemsEnvironmental comfort has become a priority concern, and the quality of the air in a room and its treatment are essential to the health and wellbeing of the occupants.
The best comfort is achieved by controlling the temperature, humidity, delivery speed and quality of the air delivered to a room in relation to its environment, which vary widely: commercial, manufacturing, hospital, etc.
A/C systems increasingly employ Air Handling Units and Systems, which treat the air to ensure suitable levels of quality, while also reducing power consumption and helping to eliminate wastage by using heat recovery units.
Air Handling Systems can satisfy the specific requirements of an application in a customised way, thus creating value for the customer. Such systems can be configured for a variety of dimensions and powers, from the simplest air handlers for small rooms to more complex centralised systems for large buildings.

Major market requirements
CustomisationThe manufacturer/installer of air handling units/systems needs to customise the machine according to his client's/market's requirements.
DifferentiationWhen designing an Air Handling System it is important to offer solutions which differentiate from the competition, and which provide maximum satisfaction for the customer.
IntegrationAll components need to integrate together for simplified and more efficient control of the system as a whole.

DifferentiationFREE Studio allows the designer to exploit his own know-how in developing unique air handling system solutions that stand out from the competition. FREE Studio allows the client to develop new functions and algorithms, at any level of complexity, without requiring Eliwell's direct intervention.
IntegrationAll FREE Way controllers are easy to connect to each other and to other system components, and enable information interchange and control of all variables - air temperature, humidity, delivery speed and quality.The terminals, with their integral temperature and humidity sensors, provide an easy and intuitive way to control of the system.
CustomisationFREE Studio enables the designer to customise his application quickly and intuitively, with savings of up to 50% in programming time. Thanks to its scalable architecture, FREE Way allows you to customise any solution from the smallest heat recovery unit to the most complex centralised system.
