NP Series

Our dream was to build a
dehumidifier that solved the industry’s
most challenging issues

Here’s how we did it

Scroll to Bottom

NP Series

Imagine

  • a dehumidifier that uses only a fraction of the refrigerant charge required in traditional systems
  • factory sealed refrigeration even on split systems
  • the most stable room conditions, smoothest operating performance and peak energy efficiency
  • no limitations on the remote AC cooler location
  • the longest lasting and most reliable dehumidifier in the industry

SERESCO

NP Series

Our revolutionary NP or Natatorium Protocol Series is the biggest industry innovation in 20 years and the future of dehumidification.

A traditional natatorium dehumidifier requires a large refrigerant charge that is not just expensive, but also leads to oil and refrigerant migration control challenges that can impact compressor reliability. Traditional split systems also severely limit the distance between the unit and its remote AC condenser.

Through the use of a secondary heat exchange fluid, our ingenious NP Series overcomes both of these issues and more. Our NP series also provides superior humidity control, exceptional reliability and lower operating costs, with as little as 1/6th the traditional refrigerant charge.

For applications requiring 100 to 840 lbs/hr hour of moisture removal or 6,800 CFM to 70,000 CFM of air handling, our NP Series beats the competition hands down – in every design consideration – every time!
