The company BGH performed the installation of various products Lennox in the Carrefour chain stores in Argentina to reduce maintenance costs and consumption of electricity and gas.

According to the website of the hypermarket chain "Carrefour was founded in France in 1959 by the families Fournier and Defforey. In the year 1960 the first Carrefour supermarket opened in the city of Annecy in the Haute Savoie department frontier bordering Switzerland. But it is only until 1963 when it opens at the intersection of roads 5, on the outskirts of Paris, the first store of 2.500 m2 sales floor, cash registers and 12 400 parking stalls. "

Since then it has become one of the chains largest and most important in the world, is proof of that supermarket expansion to countries in almost every continent. In the case of Argentina the chain came to this South American country in 1982, in that year opened in the town of San Isidro, in Buenos Aires, the first Carrefour store in that country. From that time began the expansion of the chain with the opening of other stores; for example, in 1984 opened the second hypermarket in the town Vicente Lopez, also in Buenos Aires, this was followed by the Carrefour hypermarket in 1986 San Lorenzo and Velez Sarsfield in 1989 Carrefour; in 1992 open two other stores and the Carrefour 1993 joined La Plata; born in 1994 first hypermarket in the country's interior: Córdoba Carrefour.

In 2000 the company merged with North Argentina chain to achieve a presence of 26 hypermarkets and 140 supermarkets in the cities of Buenos Aires and Greater Buenos Aires, Mar del Plata, La Plata, Mendoza and Cordoba, among others . Although since then have opened some other stores, the above figures give an idea of ​​the importance of this chain of hypermarkets.

It should be noted the size of the stores, which can reach up to 25.000 square meters, precisely therein lies the importance of the installation by BGH with Lennox products. "Three years ago, given the quality problems with other brands, we could be taken into account by Carrefour as a valid alternative, despite being more expensive than our competitors. Carrefour is a client that assesses and analyzes the efficiency of equipment and therefore Lennox is very difficult to beat, "said project managers about the working relationship with the French company.

As a result of this working relationship has been achieved savings of thousands of dollars in maintenance with payback equipment for about a year, said Diego Simondi, business manager of BGH.

It also states that this relationship has been maintained due to "mainly the trust and confidence that gives the representative (BGH) with stock permanent equipment and spare parts and working together with Lennox of over 14 years. In addition Lennox was able to impose its quality in the Mercosur region where large OEMs at a lower price ".

The main reasons were the Carrefour hypermarkets to request services BGH were permanent increases in maintenance costs and power consumption, "they looked for the best option on the market in quality and energy savings, so they contacted BGH Lennox exclusive distributor in Argentina and Chile, "said Diego Simondi. The project basically covers the provision and installation of more than 2000 Tr for new store openings Carrefour in Argentina.




As indicated Simondi "the first thing that surprised everyone was the practicality of Lennox packages, as once in position and made the wirings, the implementation of the systems was immediate and smooth, something not so common in this type of transitions; The second improvement is that they have already seen savings in equipment maintenance for ease in them to do it quickly and safely. Finally what are starting to get results is with regard to energy saving and in the first days of operation measurements exceeded customer expectations. "

This thanks to the censors CO2 used with Series L Rooftop systems which determine the amount of CO2 the environment, inform the team when it should open the outside air intake and thereby saving approximately achieved was achieved one 20% energy.


The teams

Multiple compressors that allow the unit to provide efficient cooling with four cooling stages. Also thermostatic expansion valves and variable frequency drives that give the unit a variable air volume.

Ease of installation is one of its pluses, it has an engine separate mount that allows easy access without removing the top panel, also a perimeter base rails provides greater integrity so that the unit is easier to handle and transport. The compressor compartment is isolated so it could check the performance of this in normal operation without interrupting airflow. In addition, cabinets are corrosion resistant.
