Device for removing moisture and/or another substance from ambient air or from a gas, the device being configured to operate alternately in an adsorption phase and a desorption phase, the device comprising:
- a vessel comprising an entry and an exit which comprise valves allowing the exit and entry to be opened and closed;
- a body of adsorption material positioned inside the vessel dividing the inside of the vessel in an upstream region and a downstream region;
- a fan arranged in the vessel for blowing air or gas through the body of adsorption material from the upstream region to the downstream region,
- a heating element arranged in the vessel for heating the air or gas inside the device;
- a condenser loop, the condenser loop comprising:
- a condenser located outside the vessel,
- a branch conduit which extends from the vessel to the condenser and which allows a branch flow of air or gas to flow from the downstream region to the condenser, and
- a condenser return conduit which extends from the condenser to the vessel and which allows the branch flow to return from the condenser to the upstream region of the vessel;
- wherein the device further comprises:
- at least one main return conduit for returning a main return flow of air or gas from the downstream region to the upstream region while bypassing the condenser.
