SERVICES - VENTILATION AND EXTRACTION IN TORREVIEJA

At Vifrisan we carry out all types of ventilation and air renewal installations in Torrevieja and the province of Alicante. Our company is registered in the RITE (Register of Thermal Installations in Buildings), which guarantees our professionalism and the quality of the services we provide.

Ventilation or air renewal consists of replacing the stale or polluted air in a room (home, offices, premises, garage, etc.) with new, clean air. This is precisely what we do at Vifrisan.

Ventilation can be carried out naturally or mechanically forced through fans and turbines. If you would like to improve the installation of your industrial or home ventilation, just ask us.


AIR RENEWAL IN DWELLINGS AND PREMISES

The technical building code (HS3) makes it compulsory to include air renewal systems and states:

"Buildings shall have means so that their enclosures can be adequately ventilated, eliminating pollutants that are normally produced during the normal use of the buildings, in such a way that a sufficient flow of outside air is supplied and the extraction and expulsion of air vitiated by pollutants is guaranteed."

GARAGES EXTRACTION

The CTE requires smoke evacuation in case of fire and obliges, among other things, that the extractors must be able to withstand temperatures of 400ºC for 90 minutes, i.e. apply an extraction of 120 l/s (432 m3/h) per vehicle space.

The REBT considers car parks as premises at risk of fire or explosion. It requires emergency lighting and supplementary power supply for car parks with more than 100 vehicles. However, ventilation is considered to reduce the risk of explosion and therefore the electrical installation can be normal.

"Garages with more than 5 vehicles are considered sites with Class I explosive atmospheres, so their equipment must be designed and built to work in Explosive Atmospheres (ATEX)".

We carry out any garage ventilation extraction project in accordance with current regulations, from the design and calculation to the installation of the ducts.

SHEET CHIMNEYS

Chimneys are defined as ducts constructed to vent gases resulting from combustion - or from a chemical reaction ("tail gases") - into the free atmosphere for dispersion in the ambient air.

In order to determine the characteristics of a chimney, it is essential to know the type of fluid expected to flow through it. Normally, these are fumes from the combustion of fossil fuels (coal, liquid or gaseous petroleum products) in ambient air. However, it is necessary to take into account the possible "contamination" of these fumes with substances released from the processes in which they are used, such as industrial kitchens, ovens, oil boilers, pellets, gas, etc.

There are several types of sheet metal ducts for smoke extraction, depending on the type of smoke to be evacuated, the most suitable and the one required by the regulations will be chosen:

  • galvanised sheet (circular or rectangular)
  • stainless steel
  • vitrified steel
  • stainless steel double wall modular

At Vifrisan we install any smoke extraction or ventilation chimney, whether it is for a restaurant, bar, boiler, basement, garage, etc.

STAINLESS STEEL KITCHEN EXHAUST HOODS

Catering establishments that have cooking elements are obliged to extract the fumes derived from cooking by means of an installation consisting of a chimney and extractor hood.

Due to the economic cost involved, and the complexity of the installation, we always recommend the advice of a qualified technician with experience in the design of a fume extraction installation. We can calculate and manufacture any stainless steel extractor hood, standard or custom-made.

AIR CONDITIONING DUCTS

There are various types of ducts on the market for supply air, external air intake, extraction, return air, etc. Among the most commonly used are the following:

Fiberglass air ducts

They are formed by cutting, folding, stapling, taping and siliconising aluminium-lined fibre panels on both sides, and can be manufactured on site in all the necessary rectangular section pieces, which is one of their main advantages. The material usually has excellent thermo-acoustic insulation properties and therefore does not require specific insulation. They are mainly used for the housing sector, premises and offices.

Generally, air conditioning ducts are installed in false ceilings, so they are hidden from view. We will only see the small grilles through which the air is distributed, which is more discreet and aesthetic, although there are also decorators and architects who prefer to install the ducts in view to give a more "industrial" style.

We carry out any fibre duct installation project on site for homes, premises or offices in accordance with current regulations, from the design and calculation to the installation of the ducts.

Sheet metal ducts

Manufactured by folding coils of galvanised steel or stainless steel sheet, and can be manufactured in both circular and rectangular cross-sections.

Sheet metal ducts are normally used in large installations. They can be painted and can thus be integrated into the design of the site. At Vifrisan we carry out any galvanised sheet metal or stainless steel duct installation project for premises, warehouses and large businesses.

Textile ducts

The new textile ventilation ducts for air conditioning, ventilation, heating, cooling, air renewal, air filtration and air purification have great advantages. Diffusion by means of textile ducts or textile diffusers offers perfect air distribution, homogeneity of temperatures, destatification and control of injection speeds.

These ducts are only valid for supply circuits as it is the air pressure itself that maintains the circular section, and cannot be used in extract or return ducts.

The most appropriate names for textile ducts are textile air distributors or air diffusers. Other names are also used, such as textile tubes, fabric ducts, air sleeves, air bags, air socks, air socks and others.

We carry out any project for the installation of textile ducts for premises, food industry, swimming pools, bakeries, etc.

VENTILATION BOXES AND TURBINES

Ventilation boxes with centrifugal fans  400º / 2h are necessary in car parks and industrial kitchens. Current regulations require the installation of 400º / 2h fans in all fume extractors in catering extractor hoods with a heat output greater than  20 KW.

We carry out any extraction/ventilation project in which you need ventilation boxes for garages, kitchens, etc. in accordance with current regulations, from design and calculation to installation.

HEAT RECOVERY VENTILATION

Heat recovery units are devices whose function is to take advantage of the psychometric properties (temperature and humidity) of the air that we extract from the building or premises, and exchange them with the ventilation air that we supply from outside. In this exchange process, outside air and inside air are not mixed.

The main purpose of a heat recovery unit is to recover the energy used to air-condition a space by transferring the heat from the air extracted from inside a room to the heat supplied from outside. We carry out any extraction / ventilation project for premises, offices, etc. that require heat recovery units.

AIR CURTAINS

An air curtain is a ventilation equipment that creates an invisible barrier over a door to separate two different environments efficiently, preventing the entry of insects, particles and fumes, without limiting the access of people or vehicles. It is also used in cold rooms for loading and unloading products.
