The ultimate construction dryer standard version BT 700 S sets standard in drying new buildings. The efficient cooling system ensures superior drying performance with a compact construction at the same time. In the metal housing, the large water tank made of transparent plastic indicates when it has to be emptied. For automatic operation, a condensate feed pump can be connected as an alternative. In case of difficult drying situations, the powerful and low-noise radial ventilator provides additional flexibility in every corner by connecting an air hose up to 3 metres, and a socket on the device.

For hiring, there is the BT 700 S with manual operation for quick handling and without connection for a condensate feed pump. BT 700 S is a condensation dryer adapted especially to the needs of hire use. On account of the simple operation (on/off switch only) user from outside the sector cannot make a mistake.

On account of the semi-pneumatic wheel especially flexible and mobile - the construction dryers can be moved easily on the wheels. No heavy carrying required. In addition, the unit has an ergonomic bracket for carrying. The front hood can be undone in seconds for cleaning the cooling system after dusty use. All parts of the BT 700 S are easily accessible for maintenance and repair through the ventilator flap. The ventilator unit and the electric components can be removed for maintenance.
