Outdoor enclosures and weather covers

Heated/ventilated outdoor enclosures for evaporative humidifiers ship to the job site completely assembled, so installation is a snap. Third-party tests ensure that outdoor enclosures provide reliable operation under extreme conditions. The GTS® (gas-to-steam) humidifier outdoor enclosure is CSA certified for outdoor operation, and the STS® (steam-to-steam) humidifier and Vaporstream® humidifier outdoor enclosures are ETL approved for outdoor operations. Weather covers for Vaporstream and STS humidifiers are fully assembled at the factory to protect against wind, sun, and rain.
