In the Green Hall enclosed premises of large business centers, even with a favorably coordinated indoor ventilation and heating solution, the issue of dry air often arises. But how to properly irrigate the premises in the bank so that moisture does not have any negative impact on technological equipment? Barclays has entrusted this solution to us. The bank's premises in the Green Hall building were subject to very strict requirements for the reliability of the equipment and ensuring the humidity parameters. We have solved this by installing a special computer program that constantly monitors the humidity deviation, intelligently calculates the appropriate indoor humidity parameters up to 10%, and ensures uninterrupted comfort of optimally humidified air for employees. The irrigation system has been working well for over 4 years.
