Master DH 721 Professional Dehumidifier
MASTER professional dehumidifiers are high-efficiency devices designed for use in work and industrial environments that are even moderately hostile in terms of dirt and machine movement.
Thanks to the possibility of draining liquids externally without using the tray.
The Master DH 721 dehumidifier is designed for continuous use 24 hours a day and can therefore be used where humidity is so high that it can create mould and various problems.

Published Aug 29, 2024 at 03:07 pm (Order date: Aug 17, 2024)I installed it a week ago inside a cave adjacent to a completely renovated dammuso. I do not have enough evidence yet to confirm its validity, at the moment I am using it H24 with continuous discharge and it works without interruption. I used it with the collection tray the first few days and was emptying the cassette twice a day. I would say that it pulls water. (Translated review)

Published Sep 02, 2023 at 02:27 pm (Order date: Aug 23, 2023)The product does well what it was designed to do: dehumidify. The only point I hadn't considered, but it doesn't create any particular problems, is that it raises the temperature of the room in which it is used by about 1-2°C... I use it for three/four hours in a row and the studio goes from 24°C to 25°C and sometimes 26°C, maybe I'll appreciate this in the colder period... (Translated review)
