DRY-O-TRON® Indoor Pool Climate Control


Dectron’s DRY-O-TRON® is the industry’s original energy recycling dehumidifier. Since the first
DRY-O-TRON® was introduced 40 years ago, thousands of units have been installed throughout the world.

Dectron pioneered the indoor pool dehumidification market by trying to resolve a problem found in all buildings with Indoor Pools: “Structural Damage due to Humidity”. In this pursuit, the Engineers at Dectron designed and manufactured the very first DRY-O-TRON®, a mechanical dehumidification system to control humidity, and at the same time, use the same energy by-products to increase comfort by controlling both pool and air temperature within the enclosure.

As the brand name, Dectron’s DRY-O-TRON® stands as:

  • The single largest pool dehumidifier “Original Equipment Manufacturer” in the world.
  • Over 35,000+ indoor pool installations
  • 40 Years of R&D resulting in the “greenest” and “freshest” feature-rich, premium systems

For facilities, owners, architects, engineers, contractors and consumers alike, this means a guarantee of quality in design and fabrication of solutions to meet the most stringent requirements for safe and comfortable indoor air.
