To avoid the formation of condensate and consequential problems the air in accommodations and storage facilities needs to be permanently dehumidified to a level below dew point.

Powerful desiccant dehumidifiers such as the high-quality Trotec devices TTR 400 D or TTR 500 D with separate internal air flow ducts are an ideal solution for these requirements.

In many cases an indoor installation of the devices is not permitted, undesirable due to the noise or impossible to realize for other reasons. Here the Drybox – especially developed for TTR 400 D and TTR 500 D – allows for the weatherproof outdoor installation of the dehumidifiers.

Via an air transport hose, the humid indoor air is sucked in, reliably dehumidified to below the interior dew point and then transported back into the room as dry air via a second connected hose in the recirculation air cycle.
