Verdict

The TROTEC TTK 166 ECO is a robust commercial and building-drying dehumidifier for areas up to 90 m² (230 m³), removing up to 52 litres per 24 hours with 300 m³/h airflow. It provides digital hygrostat control from 10% to 95% in 1% steps, a temperature and humidity display, R290 refrigerant, memory restart, a 7-litre tank with auto-stop, continuous drainage, and large transport wheels. The 56 dB(A) noise, the lack of a supplied drain hose, and the single fan speed are practical limitations.
