As in houses, in any store a good ventilation is necessary given the constant presence of people entering and leaving the premises. In addition to having clean air, the place will have a comfortable and healthy environment for the people who live in it at all times. Fans and energy recovery units are essential to offer this comfortable environment.
In the entrances of businesses or shops, mainly those that are at street level, it is important the installation of air curtains to avoid the loss of temperature (cold of the air conditioning in summer, or heat of the heating in winter) when people enter and leaves the premises. Casals offers the air curtains COURSALIS (air curtain just with air) and COURSALIS E (with resistance to supply hot air if desired). Both have remote control.
