The high dehumidification performance with high fan speed ensures good air circulation in the washroom. The running dehumidifier also releases some heat to the washroom. This combination creates a laundry drying effect.
Thanks to the five-fold filter technology (activated carbon filter, pre-filter, TRUE HEPA filter H13 according to EN 1822 with nano silver coating, UV-C lamp and ioniser), clean breathing air is created. Per day, this powerful condensation dehumidifier removes 10 litres of moisture from the interior air at an ambient temperature of 30°C. The moisture is collected in a large water tank with 3 litre capacity.
Condensation Dehumidifier The most common method of dehumidification is the condensation dehumidifier, also known as compressor dehumidifier. These electric dehumidifiers are used to eliminate moisture in homes, bedrooms, offices, holiday homes, caravans and trailers. The great advantage of the compressor-controlled condensation dehumidifier is that it requires 25-60% less power than an adsorption dehumidifier.
CA-704 Smart has an automatic defrosting function. As soon as the sensor signals a temperature below the set value, the defrosting starts automatically and also stops automatically. During the defrosting process, the evaporator is made ice free again by stopping the cooling process and turning on the fan. As a result, the ice melts. When restarted, the dehumidifier automatically continues to work and preserves the settings.
