Due to water damage in our cellar we needed very quickly a Bautrockner and have encountered on the Internet on this, who had received in the magazine "handyman" a positive review. The device was within a day with us. Construction and operation proved a very straightforward and the unit was in the next few weeks in continuous operation, where it performed his duty properly. More Details: It can be the operating time or a desired humidity level between 70% and 30% select - the device works until the bucket is full or the setting has been reached. Who has the power of a pump sump or a permanent drain option can use the supplied hose as an alternative to water collection tank. In addition, the device has a heating function, which provides in cold rooms or generally for faster drying. All in all: Absolute satisfaction with goods and services (supply).
