Adsorption dehumidifier A4 110V is developed for efficient operation on commercial and construction sites.
The adsorption dehumidifier A4 110 Volt version is part of Corroventa’s commercial and construction line, designed for both small and large dehumidification assignments. The dehumidifier can supply an air volume of 250 m³/h and a drying capacity of 17 l/day at 60 % RH and 20°C.
The A4 110V enables fast deployment and intuitive operation, thanks to its easy-to-use analogue controls – making it suitable for everyone, from occasional users to professionals. With a compact and robust design, the adsorption dehumidifier delivers powerful performance across a wide temperature range – from heated environments to cold, unheated spaces with varying humidity levels. This makes it ideal for use on construction sites to ensure optimal climate conditions and speed up the building’s drying process. The A4 110V is built to withstand tough conditions and deliver long-term reliability.

This unit is suitable for both general moisture control and complex structural drying tasks. It works standalone to produce dry air that helps reduce moisture in ambient air and dry materials in open spaces, such as construction sites or water-damaged areas.
In more specialised drying scenarios, the A4 110V can be used in combination with a turbine to perform pressure drying of layered structures. Effective drying requires systems that can push dry air through these layers, and that’s where the turbine and adsorption dehumidifier work together to deliver targeted, efficient drying.
A rule of thumb is that you should strive for approximately two air changes per hour when using an adsorption dryer. An A4 110V adsorption dehumidifier with a dry air flow of 250 m³/h can therefore be sufficient for a room of 50 m² if the height to the ceiling is 2.5 meters.
Keep in mind that open windows, doors, or unsealed areas will affect the drying conditions. The more air leakage, the greater the capacity required. Enclosed spaces provide better control and more efficient drying. Make sure to assess and understand the specific conditions of the area before starting the drying process, to ensure the best possible results.
Yes, the wet air must be vented externally. The dehumidification process is based on adsorption, where moisture is bound to a drying material inside the unit. The captured moisture is then released as humid air (wet air), which needs to be directed out of the room or targeted area. Make sure there is a duct or opening available to allow the wet air to exit. If not properly vented, the moisture may remain in the space, reducing the efficiency of the drying process.
The servicing requirements depend on the conditions in which the unit is used, such as dust levels, humidity, and operating time. Regular checks and cleaning help ensure optimal performance and extend the unit’s lifespan. Read the manual for detailed maintenance and service recommendations.
The choice of dehumidifier for a specific project depends on several factors, including moisture levels and temperature conditions. Corroventa’s adsorption dehumidifiers, such as the A4 110V, are designed to perform reliably across a wide temperature range and in varying humidity levels — from -10 °C up to +35 °C. This makes them versatile and ideal for use in both cold environments, like unheated construction sites, and warmer conditions. Their broad operating capability ensures effective moisture removal regardless of climate, helping maintain efficient drying performance all year round.
Yes, the unit is designed for continuous operation and can safely run 24 hours a day. For added efficiency and control, it can be connected to a hygrostat, which automatically stops the dehumidification once the desired humidity level is achieved, while the fan will continue to run. This helps optimise energy use while maintaining effective moisture control.
Yes, A4 110V features two fan speed settings – high and low – which can be easily selected using the High/Low button. This allows you to adjust airflow based on the drying needs of the environment, helping optimise performance and energy use.
