A well-designed ventilation system is essential for any building, providing quiet, energy-efficient, and effective air circulation. It can help maintain the right air temperature and humidity for customers, employees, goods, or production processes.

Proper design is crucial for an effective system, as any mistakes will have long-term consequences. Take the time to ensure your ventilation system is optimally designed for your needs.


We know from experience that the initial purpose of a building may quickly change or evolve. As your business grows, new ventilation needs arise. Alterations or modifications to the ventilation system are generally costly and complicated. Therefore, when designing a ventilation system,think ahead about the building's future needs. The ventilation system needs to be designed while considering any anticipated changes such as increase in production, changes or expansions in the product range, workforce growth, and other factors.


Any mistakes made at the stage of designing a ventilation system will result, in the best case scenario, in occupant discomfort (caused by, for example, its inability to achieve a desired temperature or noticeable noise generated by ventilation devices) and, in extreme cases, in significant financial losses.

To avoid this, contact a HVAC Ratherm representative. With our extensive knowledge and many years of experience, we can help you design the most optimal ventilation system tailored to your project's current and future needs.

HVAC Ratherm is an experienced manufacturer of ventilation systems. We have delivered several hundred projects for some of the largest Polish companies and plants. More information about our projects can be found here: Our Projects.


One of the most important steps in designing a ventilation system is the choice of ventilation equipment. There are many HVAC solutions by various manufacturers available in the market. A thorough analysis of all offerings should precede any final choice. A ventilation system is usually quite expensive, so take the effort to look into various ventilation system manufacturers and their products.

Here are some examples of the criteria you might want to focus on:
  1. Experience
    As in any other industry, the experience of a HVAC system manufacturer is important. HVAC Ratherm has for over a decade specialised in the construction and installation of ventilation units.We have delivered hundreds of projects throughout Poland. Our ventilation systems have been purchased by all sorts of businesses, including large industrial facilities (see our projects for industrial facilities),manufacturing plants, shopping centres, hospitals, warehouses, logistics centres, etc. (see all projects).If experience is an important criterion for you, you can rely on HVAC Ratherm to deliver.

  2. Price
    This is the most obvious factor, but it can also be a trap. The price must be attractive for the project owner while still reflecting the quality offered. A low price may come with low quality, performance issues, and high operating and servicing costs. When analysing different offerings, do not focus solely on keeping the price as low as possible. In many cases, choosing a more expensive but a more comprehensive package from an experienced supplier will turn out to be more cost-effective. High quality of equipment and the entire ventilation system can translate into lower operating costs and significantly lower failure rates in the future. When choosing ventilation equipment, investigate the price-to-quality ratio.
  3. Performance
    The most important function of a ventilation system is to supply of fresh air and remove aged air. A correctly designed ventilation system changes air in the entire building in an efficient and fast way. Therefore, the efficiency of ventilation equipment is a very important factor. The ventilation system as a whole must be able to supply the required amount of air.

    HVAC Ratherm offers various types of HVAC units, including: XD monoblock AHUs, XK compact AHUs, XK-G gas-fired AHUs, XK-P suspended AHUs and XD-HP AHUs with internal heat pumps. Our range of products includes AHUs with an air flow rate ranging from 1,000 m3/h (such as the XK 015 compact AHU with a rotary heat exchanger) to 38,000 m3/h (such as the XD 340 monoblock AHU).

    To select the most optimal ventilation equipment, use our helpful AHU Configurator. It is a convenient tool to help you choose a suitable AHU in four simple steps. The Configurator also offers predefined AHU sets with automation applications. Our app is also popular because of its simple and clear navigation.

  4. Appearance
    Ventilation systems can be quite complex and extensive. In industrial buildings, warehouses, distribution centres, logistics centres, production floors, and similar facilities, the appearance of the ventilation system is not that significant. However, this is not the case in office, commercial, retail, and residential buildings. The ventilation system should seamlessly integrate into its surroundings, appearing as inconspicuous as possible.
  5. Cost-effectiveness
    The ever-increasing energy prices may significantly rise the cost of heating and cooling a building. Therefore, when designing a ventilation system, attention should be paid to energy efficiency of the equipment. Nowadays, this is a very important criterion for selecting ventilation units.
