The essential elements from the climatic point of view are the speed and quality of the air in the room, which must guarantee well-being and health (preventing the ‘sick building syndrome’) taking into account the local climate, variable crowding in different situations and at different times of day, and temperature differences between adjacent areas.

For this to be possible, some indispensable requirements of air conditioning systems are suggested:

  • temperature, relative humidity and air speed
  • flexibility in the use of space
  • high environmental comfort
  • low energy consumption
  • air quality
  • small space requirements in room and technical rooms
  • low investment costs
  • ease of maintenance

INERTIA FILTERS

Inertial separation is an excellent pre-filtration system, particularly suitable in environments with high dust concentration as desert areas, mines, steel and foundry factories, cement industries.

Inertial separation is an excellent pre-filtration system, particularly suitable in environments with high dust concentration as desert areas, mines, steel and foundry factories, cement industries.
This filtration system is based on the principle of conservation of kinetic energy by the airborne dust particles. Thanks to a series of quick changes in direction, while the clean airflow is being employed in the process, through inertia the particles continue moving in a straight line till they eventually reach the unloading hopper. There, thanks to a small volume of air handled by a bleed fan (around 10% of the total inlet air volume), the particles are exhausted outside.
Obviously, the higher the mass of the particles handled and the speed through which they are transported, the higher the efficiency of an inertia filter. In any case the filtering system efficiency is based on the bleed fan correct operation.

PRESSURIZATION UNITS

Pressurization units are filtering and ventilation systems
They ensure positive pressure in the environment and prevent crossed contamination filtering airborne dusts and gases
They are used in controlled contamination environments, not only as cleanrooms but also as fallout shelters etc.
Sagicofim design and manufacture them according to each Customer’s project technical specifications

CHEMICAL FILTERS

SagiCofim offer a range of air filtering systems capable of treating chemical, nuclear and bacteriological agents, thus protecting operators’ safety and machinery continuous operation even in case of catastrophic events, as an explosion on an oil rig or in a nuclear power plant, in a chemical, pharmaceutical plant or laboratory.

SagiCofim face the real threat and develop the most effective solution both at a technical and compliance level, the latter of which is carefully documented.

PULSE JET FILTERING SYSTEM

Single and multi-stage self-cleaning filter systems.
These systems are designed to operate in highly dusty areas.

CONVENTIONAL FILTERING SYSTEMS

Conventional filtering systems are single- and multi-stage filtering systems which require periodic replacement of filters when foul.

AIR INTAKE ACCESSORIES

Air intake accessories are supplied as supplements to integrate filtering and ventilation systems, e.g. rain protections, adjusting dampers, silencers, etc.

CANISTER SYSTEMS

Canister safe change filter housings are used for the tight accommodation of filters subject to air flows containing noxious, toxic, radioactive substances, etc. They are especially used in industrial plants, laboratories, and process applications.

Canister safe change filter housings are used for the tight accommodation of filters subject to air flows containing noxious, toxic, radioactive substances, etc. They are especially used in industrial plants, laboratories, and process applications. Their main feature is to allow the maintenance personnel to safely replace the exhausted filters, both absolute and activated carbon. In fact the operator never touches the filters because they are insulated inside a protection bag where they are sealed and then disposed of. This operation is also very safe for the surrounding environment.
The new filters are then handled without any direct contact. They are pulled out of their protection bags (bag-in, bag-out procedure).

BLAST PROTECTION SYSTEMS

Protecting industrial buildings close to potentially explosive areas is a must in the petrochemical sector. When the effects of a possible accident, which might pose a threat not only to the operators’ safety but also to the integrity of highly technological machinery must be avoided, we shall rely on products of excellence capable of responding promptly and effectively.

SURFACE MOUNTED BLAST ATTENUATORS
The blast attenuators SMBA are stationary louvered type attenuators to be installed for the protection of HVAC air intake and outlet openings of the specified buildings subjected to a blast design overpressure lower than 0.07 barg (7 kPag), where the blast protection valves would not however close due to insufficient overpressure.
