Which dehumidifier works best during the winter?

  • Faster drying process with a dehumidifier with an extra heater

    An adsorption dehumidifier is absolutely the best alternative during the winter when the air is cold and dry. The air has generally quite high relative humidity but very little moisture in the air which makes a condensing drier less effective. With an extra heater as in Corroventa’s A4 ESX, you get extremely hot and dry air from its four outlets. This contributes to an optimal drying process all year round but especially during this period. Depending on the operating mode and with or without the extra heater, the increase in temperature is between 5-55 °C.

    Adsorption dehumidifier A4 ESX has a capacity of 27L/24 hours already at 60 %RH and 20 °C. As a member of the ES-family it has many built-in operating modes which optimizes the effectiveness of the drying process at the same time as it has a lower energy consumption than traditional dehumidifiers. If you want to save even more time and money you can connect it to SuperVision which gives you the opportunity to remotely control the process.

    “The focus on the whole ES-series was user-friendliness from the drying technician’s perspective. We wanted to create one machine that could do everything from the small project under a kitchen sink to the large water damage, quiet, fast and energy-effective. We didn’t find anything like that on the market, it always demanded several different machines alternatively that you used a machine that was not optimal for a particular project.”

    What makes dehumidifiers from the ES-series extra beneficial is the so called Delta-X mode which means that it produces less but drier air. The air coming out of the machine is extremely dry. This is perfect for slowly dried materials such as concrete and brick. A bathroom floor is an example where drying using a plastic enclosure and the use of Delta Z is optimal.


    When having a water damage in a bathroom where the drying process can be difficult we recommend to wrap the damaged area in plastic to restrict the area and then use an adsorption dehumidifier. The plastic enclosure helps speeding up the drying process and get the maximum capacity out of the drier and you don’t need as many machines. Read more about plastic enclosuring here.
