Dectron is undoubtedly the world’s premier manufacturer of energy recycling mechanical dehumidifiers, having introduced the industry’s first such equipment back in the 1970s. 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.

Innovations such as “Purge Mode” and “ChloraGuard” allow Dectron to continue in its roles as the leader in indoor pool environmental control.
