What's behind these devices?
The new TurboCool models are not air conditioners in the traditional sense. Instead of refrigerant, they use water, which is finely atomized and combined with the airflow. The evaporation process creates a cooling effect, similar to a breeze, which feels noticeably fresher.
The main advantages of evaporative coolers lie in their energy consumption and ease of use. They require significantly less electricity than air conditioners and don't need an exhaust hose or complicated installation. However, they don't actively cool rooms, but rather create a perceived cooling effect in the vicinity of the unit.
TurboCool 765S: noticeable airflow in the room
The TurboCool 765S was set up on-site as a larger model and ran both indoors and, at times, towards the patio. Technically, the system is based on an atomization rate of up to 800 ml/h with very fine droplets (around 17 μm), which are distributed throughout the room at an air velocity of up to 10 m/s and are designed to provide a cooling effect of up to 6 °C. The 6-liter water tank is designed for extended runtimes and is intended to allow up to 24 hours of operation in low mode. It also operates relatively quietly at around 20 dB.
The most impressive feature on-site is the strong airflow, which is noticeable even at a distance. Standing directly in front of it, the slightly cooling effect becomes apparent. Incidentally, it doesn't produce excessive water mist, which, according to DREO, is one of the key differences compared to many conventional evaporative coolers, which often lead to a clammy feeling in the room after a while.
TurboCool 516S: compact for close-range use
In addition to the larger model, a significantly more compact version, the TurboCool 516S, was also on display. Instead of cooling large rooms, this device is designed to cool specific areas, such as desks, balconies, or seating areas.
Technically, this model also works with the same basic idea, albeit on a smaller scale. The air velocity is slightly lower at up to 8 m/s, as is the stated cooling capacity of up to 3 °C. The water tank is significantly smaller at 1,3 liters, which means shorter operating times but simplifies handling.
Initial practical experience quickly reveals that the cooling effect is most effective at close range. While noticeable when sitting directly in the airflow, the effect diminishes significantly with distance. As with the larger model, no visible water mist is emitted.

Overview of other devices
In addition to the two TurboCool models, DREO also showcased other products. These included the TurboPoly 765S fan, which focuses less on evaporative cooling and more on achieving the most even air circulation possible in the room. The device can be used flexibly as a table or pedestal fan and, according to the manufacturer, supports wide-area air distribution through three-dimensional oscillation. Integration into smart home systems via "Matter" is also planned.
Also part of the lineup is the 318S portable air conditioner. It uses classic compressor technology, but a drainless system is designed to reduce maintenance. With a cooling capacity of 7.500 BTU, it is suitable for cooling smaller rooms up to approximately 20 m².
