Indoor Pool Dehumidification
Indoor pool dehumidification in Ontario is commonly achieved using a specially designed system that efficiently recycles energy from the evaporated pool water in the air, back into the pool. The system focuses on three key metrics: air temperature, pool water temperature, and relative humidity to maintain a desired climate in the room. At King Air, we are experts in all aspects of this system. The most common indoor pool dehumidifier model is the Dectron: Dry-o-Tron, our family has serviced some of the same Dry-o-Tron systems for over 30 years, which are still running strong.
Our long-standing commitment to the industry has allowed us to develop and maintain a close relationship with the Dectron, Seresco, and Pool Pak brands; the leaders in indoor pool dehumidification. This relationship allows us to have direct communication with manufacturer representatives; reducing costs and turn around time for repairs.
“King Air has serviced all three of my locations for years. Frank has always been a reliable and fair contractor and his team are always able to solve issues that arise.”
