Ventilation systems Manufacturers online

Ventilation systems are technical systems that improve the indoor climate, protect against moisture and mold and at the same time increase the energy efficiency of modern buildings.

They ensure a continuous exchange of stale indoor air with fresh outdoor air.

Below you will find the function and types of ventilation systems, their use and their advantages:

How ventilation systems work:

Ventilation systems are used for controlled ventilation of indoor spaces.
They remove stale air contaminated with CO₂, moisture or pollutants to the outside and replace it with fresh outside air.
Modern systems often work with heat recovery so that the energy from the exhaust air is used to preheat or cool the fresh air supplied. This results in a continuous exchange of air with high energy efficiency.

Types of ventilation systems:

There are different designs that are used depending on the area of application:

1. Mechanical exhaust air systems:
   Actively remove stale air via fans, while fresh air flows in via leaks or supply air openings.
2. Central supply and exhaust air systems with heat recovery:
   Provide controlled air flow in all rooms, save heating energy through heat exchangers and are now standard in energy-efficient buildings.
3. Decentralized ventilation units:
   Are installed room by room, often with integrated heat recovery, and are particularly suitable for refurbishments or individual rooms.
4. Special ventilation systems:
   These include systems for clean rooms, hospitals, laboratories or industry that meet high requirements for air purity, temperature or humidity.

Use of ventilation systems:

Ventilation systems are used in many areas:

1. Residential buildings:
Improving air quality, moisture protection and energy savings through heat recovery.

2. Offices and schools:
Ensuring a supply of fresh air, increasing the ability to concentrate and reducing the risk of infection.

3. Industry and commerce:
Ensuring occupational safety, removal of pollutants or process heat, air conditioning of production areas.

4. Healthcare:
Controlling germs, particles and odors in hospitals, laboratories or care facilities.

5. Gastronomy:
Removal of cooking fumes, humidity and odors in kitchen and dining areas.

Advantages of ventilation systems:

Ventilation systems offer numerous benefits:

• Health and comfort: a continuous supply of fresh air improves the indoor climate and reduces pollutants, allergens and germs.
• Moisture protection: Prevents mold growth and structural damage through controlled removal of humidity.
• Energy efficiency: Systems with heat recovery significantly reduce heating and cooling costs.
• Automation and control: Modern systems allow precise control of air volume, temperature and humidity.
• Flexibility: From decentralized individual units to complex large-scale systems for industry and public buildings, there are solutions for every requirement.
• Sustainability: Energy-efficient ventilation concepts can reduce CO₂ emissions and meet legal requirements for climate protection.

Ventilation systems are central components of modern building and air conditioning technology. They ensure healthy air, protect the building fabric, increase energy efficiency and make a significant contribution to comfort in living, working and special environments. Depending on requirements, various systems are available, from simple exhaust air solutions to highly developed central systems with heat recovery.

Here you will find an overview of the most important criteria that you should pay attention to when purchasing ventilation systems:

When purchasing ventilation systems, it is crucial to give equal consideration to the technical requirements, the specific use of the building and the long-term operating costs. A well-founded selection determines the energy efficiency, comfort, health and cost-effectiveness of the system.

• The right design is the basis of every investment.
• A precise analysis should be carried out before purchasing: Room size, number of people, use (residential, office, industrial, healthcare) and climatic conditions determine the amount of air required.
• Incorrect dimensioning leads either to inadequate air quality or unnecessarily high energy and operating costs.
• Depending on the building and use, the choice between different system types is crucial:
• Centralized systems are suitable for larger buildings or new buildings where uniform ventilation and heat recovery are important.
• Decentralized units are flexible and particularly useful for renovations or individual rooms.
• Special systems are used in hospitals, laboratories or clean rooms where there are high requirements for air purity, temperature and humidity.
• Efficiency is a key factor in operating costs.
• Modern systems have heat recovery systems that recover up to 90 % of the heat energy from the exhaust air.
• The efficiency of the fans and the controllability of the system are also crucial in order to minimize energy consumption and meet legal requirements such as the Building Energy Act.
• The system should ensure a constant supply of clean, fresh air. High-quality filters, e.g. F7-F9 or HEPA, are important to remove fine dust, allergens or pollutants from the outside air.
• For special applications, such as in medical facilities or industry, the filters must be adapted to the pollution that occurs there.
• In residential buildings, schools or offices in particular, noise levels play a major role.
• A high-quality system works quietly without compromising air quality or comfort. In addition, the air flow should be draught-free and uniform.
• Modern systems offer intelligent controls that adapt to the CO₂ content, humidity or use of the building.
• Ease of operation for users and integration into building management systems (BMS) or smart home systems are other important aspects.
• Professional purchasing must take life cycle costs into account.
• This includes not only the purchase, but also the running costs for energy, filter changes, inspections and possible repairs.
• Systems with easily accessible components, standardized filters and good spare parts service are more economical in the long term.
• Choosing a reliable manufacturer with proven experience and reference projects is crucial.
• Clear warranty conditions, service contracts, technical support and the availability of spare parts over many years are important.
• A competent partner provides support from the planning stage through to operation, thus ensuring security.
• In addition to efficiency, the question of amortization also plays a role. State or regional subsidy programs can make the investment considerably easier, especially if the system demonstrably contributes to energy savings.
• Before making a purchase, you should check whether the desired solution is eligible for a subsidy.

When purchasing ventilation systems professionally, it is important to carefully weigh up requirements, system type, energy efficiency, air quality, comfort and operating costs. Equally important are a reliable manufacturer, good maintenance conditions and integration into modern building technology. If you take these points into account, you will get a solution that guarantees healthy air, a high level of comfort and economical operation in the long term.
