Wetted Media Systems – DriSteem
DriSteem says it has introduced three new product options for the Wetted Media System, meeting the requirements of today’s systems that often require cost efficient evaporative cooling and humidification. New options for DriSteem Wetted Media Systems include:
- New media size
In addition to 12-in (305 mm) media, DriSteem now offers 8-in (203 mm) media for situations where there is lower demand. Eight-inch media restricts flow rate less than 12-in media, resulting in a lower pressure drop.
- Built-in droplet separator
Order the system with a built-in droplet separator to remove water droplets that can form when operating at higher face velocities. The ability to operate at higher velocities delivers more conditioned air to a controlled space.
- User-controlled version
The user-controlled Wetted Media System does not include the DriSteem Vapor-logic® controller, which the company says saves on cost while maintaining the flexibility to work with an existing BAS.
Wetted Media Systems work by using the heat already in the air to evaporate water as it passes through saturated media, saving on energy costs compared to alternative evaporative cooling equipment or steam humidification. In addition, the Wetted Media System can effectively manage shoulder season cooling load, as well as assist on peak cooling days to avoid the purchase of additional cooling equipment. According to the company, in retrofit situations where the cooling load has increased, installation of a Wetted Media System is significantly less costly than adding a chiller.
