We have been active in the professional refrigeration sector for many years: • Commercial installations • Air conditioning • Heat pumps • Wine cellars As respect for the environment is one of our priorities, we make every effort to build installations using the most respectful and reliable components. FRIGO Service SA also offers an efficient breakdown service and a high-quality maintenance contract. Refrigeration Refrigeration refers to all the refrigeration processes used to lower the temperature in a closed space in order to maintain and preserve the sanitary condition of products and foodstuffs, usually food. The cold stops bacterial growth and slows down undesirable chemical reactions to extend a product's shelf life. Refrigeration is a food preservation technique that forms part of the cold chain. Air conditioning Air conditioning is the process of controlling, regulating and modifying climatic conditions, mainly for comfort or technical reasons in specific areas such as medical laboratories, operating theatres or computer rooms. Outside these areas, air conditioning is mainly used to cool a room where the temperature is too high, or to regulate humidity levels. Heat pumps Heat pumps are thermodynamic heating systems that use renewable energy. The heat pump takes the calories present in a natural medium - air, water, earth or soil - and transfers them by amplifying them to another medium, such as a building or a dwelling, in order to heat it. Wine cellar The ‘right’ temperature plays a vital role in the world of wine. For perfect wine tasting.
