Fresh-Air Single-Flow Haze-Removal Dehumidification Purification System

    The ROTER-LT-S series is a proprietary design of Roter. It employs a unique method to combine the direct expansion (DX) system and the purification system into an integrated fresh-air single-flow dehumidification and purification system. This model is particularly suitable for delivering dried fresh air to locations that require it, or for recirculation within designated spaces. It can also serve as a single-flow fresh-air system installed outside rooms in special environments (e.g., paint booths and areas with hazardous gases). Once the humid air is purified and dehumidified, it is supplied into the room and can likewise function as equipment for fresh-air and positive-pressure systems. Maintaining a long-term positive-pressure fresh-air environment resolves bacterial growth and dampness issues while ensuring an adequate oxygen supply.
