Anadrasi is based on its many years of experience since 1986 in the field of Ventilation Systems and in combination with the continuous information and training of its Engineers and Technicians in new modern and advanced techniques and methods as well as with significant investments that are constantly made in engineering. equipment and tools can offer Ventilation System Installations that fully meet the above requirements and needs and can really make a difference by achieving:

• Optimal air purity conditions in the interior of each building.
• Protection of the environment from pollution by gaseous pollutants.
• Full compliance with Greek and European Community legislation and with regulations for interiors and for the environment.
• Maximum energy savings and low operating costs. High levels of automation both for ease of operation and services as well as for recording and controlling energy consumption.
• Optimal functionality.
• High aesthetics.
• Quality and economical construction (value for money).
• High technological level that meets modern requirements.
• Full harmonization with the most modern technical specifications and requirements.
• Selection of reliable equipment.
• Ease of operation, use and maintenance.

Simple Central Ventilation

Simple central ventilation systems which include centrifugal fans (fan section) for exhaust air intake and fresh outside air supply through metal air ducts and air diffusers for exhaust and supply air.

Such installations are applied in spaces for which there are not special requirements, except for the requirement for a simple air renewal. They are used in industrial and general warehouses where there is not special production of pollutants and where there are not special requirements for the purity and temperature of the supplied ventilation air. They are often applied in public gathering places and cafes, restaurants, bars, taverns, nightclubs, grills, etc.) as well as in sport facilities.

In this type Ventilation Systems of installation there is not possibility to control the temperature of the air supplied in the space. In this case the temperature of the supplied air will be that of the surrounding area. For this reason, such installations are recommended for spaces without special requirements for room temperature in which the ventilation system is to be installed.

Central Ventilation with filtration of the supplied and/or exhaust air

Central ventilation systems with air filtration include centrifugal fans (fan section) for exhaust air intake and fresh outside air supply, filter units for filtration of either fresh air supply or exhaust air from the interior, metal air ducts and air intakes, as well as various controls or pollution sensors to control the operation of the installation.

Such installations are applied in areas with special requirements either for the purity of the supplied fresh air or for the retention of any environmentally hazardous air pollutants.

For the filtration of the supplied fresh air and depending on the purity requirements, either simply washable air filters are used or in combination with bag filters for dust retention or even absolute filters for the retention of microparticles.

Depending on the type of pollutants, either dust filters or activated carbon filters are used to filter the exhaust air inside the room, if there is a production of unpleasant odors or pollutants from organic solvents inside the room.

Ventilation facilities of this type are used in industrial areas (mainly food, pharmaceutical and chemical industries, etc.) as well as gyms, swimming pools, dance halls, indoor stadiums, general hospital areas, computer rooms, etc. In these systems, the temperature of the air supplied for ventilation is also that of the environment. As these systems are usually applied in installations with requirements for smooth fluctuation of the supply air temperature, special measures are taken, such as the installation of air heat exchangers, in order to avoid unpleasant currents from the supplied air, minimize cooling and thermal loads from it and thus saving energy.

Ventilation Systems for the extraction of flue gases from hoppers

Ventilation Systems for the extraction of flue gases from hoppers are suitable for professional kitchens of restaurant, hotel kitchens, taverns, steakhouses, pizzerias, etc. and include stainless steel hopper, special centrifugal fan with rear wings, suitable for exhaust from professional kitchen hoppers, metal air ducts as well as special multi-speed controls or inverters to control operation of Ventilation

Central Ventilation systems in combination with air conditioning and heating (complete air treatment), pre-air conditioning, humidification, dehumidification, filtration

Installations of central ventilation systems with complete management and treatment of air, according to the requirements of each installation (heating, air conditioning, pre-cooling or preheating, free cooling, heat exchange - exhaust air, humidification or dehumidification, filtration, etc.).

These are integrated ventilation systems that are usually part of a central air conditioning installation of a building and consist of central air handling units, air supply networks, air, air exhaust, return and air discharge as well as nozzles for supply and exhaust of air from the premises of the building. Its size as well as the equipment that includes a central air conditioning unit varies, depending on the size and requirements of each installation, starting from very simple units with the basic equipment (exhaust and supply fans, cooling - heating element and simple washable filters ) and reaching fully equipped units with special filters, special regulating dampers, humidification or dehumidification systems with post-heating, air exchangers, air control and management automations, etc.).

Integrated ventilation installations are the most suitable solution for any application, whether it concerns commercial or industrial space. However, due to the higher cost compared to other ventilation systems, they are usually applied in facilities of special requirements such as food and drug industries, hospitals, large office spaces, meeting rooms with quality standards, gymnasiums, swimming pools, dance halls, computer rooms, etc.

Ventilation - Dusting systems of industrial installations (Industrial Ventilation).

Installation of central ventilation - detonation systems in industrial areas exposed to very high dust pollutants.

These systems are divided into two main categories:

• Dusting and ventilation systems with industrial filters, which usually include self-cleaning filters with the help of compressed air, self-cleaning filters with the help of vibrator, bag filters, filter cassettes and special cages, ventilation networks from metal air ducts and various filter accessories.
• In separation detonation systems (filter cyclones/air vents) which usually include filter cyclones with built-in self-cleaning filters, cyclones, air vents and horizontal air vents with agitation for difficult flow products.
