In the realm of HVAC technology, air handling systems stand as crucial game-changers, balancing comfort with efficiency. Dive into this exploration of air handling units, particularly spotlighting Saiver’s innovations available through IACS. Looking for top-notch energy efficiency and cost savings? You’re in the right place.

What are air handling systems?

Before we get into the efficiency and cost savings that can be achieved by products sold by IACS, let’s briefly explore exactly what air handling systems are. Air handling systems, often referred to as air handling units (AHUs), are integral components of HVAC (heating, ventilation, and air conditioning) systems.


Their primary function is to treat the air, ensuring it is clean, adequately humidified or dehumidified, and at the desired temperature, before circulating it throughout a building or facility. These systems play a pivotal role in maintaining indoor air quality and ensuring comfortable conditions for occupants.

How air handling systems work

  1. Air intake: Air is drawn into the system, which can be a mix of fresh outdoor air and recirculated indoor air.
  2. Filtration: As the air flows through, it’s first filtered to remove contaminants.
  3. Temperature adjustment: Depending on the need (cooling or heating), the air is passed over the respective coil to bring it to the desired temperature.
  4. Humidity control: If required, the system adjusts the humidity levels using humidifiers or dehumidifiers.
  5. Distribution: The treated air is then circulated throughout the building using ductwork and fans.
  6. Exhaust: A portion of indoor air is often exhausted outside to regulate air quality and pressure.


By performing these functions, air handling systems ensure a consistent and comfortable indoor environment, free from excessive pollutants, and at desired temperature and humidity levels.

How do Saiver’s air handling systems lead to energy efficiency and cost savings?

Saiver’s air handling systems such as the A1 Series, employ a range of features and design principles that significantly contribute to energy efficiency and subsequent cost savings. Let’s delve into the details:

Advanced cooling systems

  • Evaporative cooling: Saiver employs both direct and indirect evaporative cooling methods. Evaporative cooling is highly energy efficient as it utilises the natural process of water evaporation to cool the air, consuming significantly less energy compared to traditional air conditioning systems.
  • Multiple options: By offering systems with direct expansion, chilled water, and liquid cooling options, Saiver ensures that the most efficient method is used for the given application and environment.

Customised design and modularity

Every facility or building has unique needs, and a standardised approach isn’t always the most efficient. By allowing for complete personalisation in dimensions and modular design, Saiver ensures that every unit is optimised for its specific application. An optimised system runs more efficiently, leading to energy and cost savings.

High-performance metrics

With mechanical resistance, air loss rate, heat transmission, and thermal bridge factor classifications that are top-tier, Saiver’s units ensure minimal energy wastage. Better mechanical resistance means the units can handle more without working harder. Lower air loss rates mean that less cooled or heated air escapes the system, ensuring optimal efficiency.

Conformity and certification

The A1 series, for instance, conforms to European regulations and has a EUROVENT certification. Compliance with such standards and certifications ensures the units operate at peak efficiency levels and adhere to best practices in the industry.

Integrated technology

Features like integrated heat pumps in some units can lead to both energy and cost savings. Heat pumps are known for their efficiency, as they transfer heat instead of generating it.

Proprietary control software allows for real-time monitoring and optimisation of the system’s operation, ensuring it runs efficiently at all times.

Durability and low maintenance

Designed for a long lifecycle and characterised by low maintenance costs, Saiver’s units reduce the need for frequent repairs or replacements. A system that requires less maintenance not only saves direct maintenance costs but also ensures uninterrupted efficient operation, preventing energy wastage and unexpected downtimes.

Specific material choices

Saiver’s emphasis on choosing specific materials for different applications, like compliance with marine standards or ATEX regulations, means that each system is ideally suited to its environment. When a system is made of materials best suited to its operating conditions, it runs more efficiently and lasts longer.


In essence, Saiver’s approach to air handling system design, combined with their advanced technology and commitment to quality, ensures that their units lead to notable energy efficiency. Over time, this translates into significant cost savings for the end-user, both in terms of energy bills and reduced maintenance costs.
