The HTT hand dryer stands out with its superior design and remarkable energy efficiency. It is the result of a reduction in power consumption from 2.8 kW to 1.0 kW and in operating time from 36 sec. to 15 sec. while drying remains equally efficient. The aim of the design is to communicate this advantage in terms of ecology and function. With its dynamic, emotional lines, directed at the air outlet and user, the impression is positive and friendly. The sides of the ellipsoid main body are slightly concave and achieve a dynamic structure and lend the housing mechanical resistance.
