Pressurized Water Distribution System
The water distribution system is enclosed and completely protected by the casing panels and drift eliminators. The eliminators also function as effective debris screens which block sunlight and prevent debris from entering the spray system. The water distribution system is made with non-corrosive materials including schedule 40 PVC pipe and durable ABS plastic water diffusers. The spray branch piping is easily removed and designed with threaded end-caps for easy cleaning. The water diffusers have wide openings with anti-sludge rings to prevent clogging from sediment and debris.

Evapco's design avoids the problems of biological growth and clogging that can occur due to a water distribution system that is open with direct exposure the surroundings.
