Desiccant Dehumidifiers: DL Range
DL15 Industrial Desiccant Dehumidifier
The DL15 brings medium‑range capacity in the compact DL Series. Its high‑performance silica‑gel rotor and built‑in purge‑sector heat recovery deliver precise, condensate‑free dehumidification. The standard Siemens touch‑panel HMI provides live readings on humidity, temperature, rotor health, and energy use—ideal for pilot plants, small production lines, and dry‑room applications.
