The ST Tower 2™ is an iteration of the original ST Tower™, created in 2009 as the first diffusion system for Scentechnologies solutions. It includes two slots to install up to two loads of Polymer™, which greatly facilitates the elimination of unpleasant odors in small spaces with persistent odors, generating little olfactory fatigue in the environment.

It is entirely composed of sheet metal, a material that is both strong and durable, yet lightweight, allowing it to be attached to surfaces with adhesives such as double-sided tape or screws. The device can be positioned horizontally or vertically. The ST Tower 2™'s performance is not affected by the availability of natural ventilation, as it has its own fan, with a power consumption of only 1.2W.

Due to its long-lasting durability, the ST Tower 2™ is an efficient solution for busy environments with persistent odors, such as common areas or restrooms. The tower's technology allows the odor eliminator to be transferred without generating excess fragrance, making it a very neutral and particularly pleasant solution.
