NE Series Dehumidifiers - The Industry Standard for Quality

Advanced Dehumidification Technology: Our NE, or Natatorium Environment line of dehumidifiers provide the very best in classic compressorized humidity control. The combination of exceptional engineering and design, plus premium components makes our NE line both energy efficient and exceptionally reliable. The NE series provides peak performance in the range of 10 to 100 lbs. per hour of moisture removal and 650 to 8,000 CFM of air handling. Although our NE line actually extends up to 1000 lbs. of moisture removal and 70,000 CFM of air handling, for larger applications requiring large refrigerant charges, our NP line has taken over as the preferred solution.

Fully Featured in Every Size: We break the line into three size categories, with each category providing design innovations, standard features and unique features that competitors don't provide. From homes and spas to hotels, schools and YMCAs, our NE line offers fully featured solutions with plenty of options. Our NE line is also designed to integrate with and provide maximum performance benefits with the Paddock Evacuator chloramine removal system.
