In the course of this process, heat is gathered and humidity condenses over the coils, similar to how a dehumidifier works.

Wholly integrated throughout the dehumidifier is often a condensate pump https://www.penmann.co.uk/blog/industrial-dehumidifiers-managing-moisture-in-controlled-environments/
