There are several supermarket chains, in Brazil and in the world, operating regionally or globally, with stores in mini-market, market, supermarket, and hypermarket formats, retail or wholesale, with one or more brands.

Generally, they are managed by large international corporate groups with high purchasing power and high stock control, making it possible to negotiate with the food distributors of the world's main manufacturers and allowing the practice of competitive prices to the final consumers.

According to ABRAS, the supermarket sector has already surpassed 400 thousand physical stores, employing about 1.8 million people throughout the country and moving more than 550 billion reais annually.

Water cooling towers are fundamental for the daily routine of supermarket chains, as they act directly on the thermal control of refrigerated and frozen products, such as fish and meat, dairy products and ice creams, fruits, vegetables, beverages, among others, dissipating the heat generated by refrigeration equipment, besides helping in the operation of air conditioning and ventilation systems for the thermal comfort of these environments.
