Evaporative cooling and humidification

Wetted Media System

The DriSteem® Wetted Media System provides evaporative cooling and humidification for a wide variety of applications. Evaporatively cool and humidify to enhance indoor air quality, manufacturing processes, material
longevity, and comfort while taking advantage of the free cooling and energy savings inherent with this technology. The DriSteem Wetted Media System delivers economical cooling and humidification in air handlers and ducts. A sophisticated water and scale management system optimizes water and media life.

Energy efficient

Evaporative cooling and humidifi cation systems draw heat from air to evaporate unheated water introduced by the wetted media system. This process raises the relative humidity (RH) level and lowers the dry bulb air temperature. Consequently, these systems humidify and cool air very efficiently.

Reduces cooling load

As water is absorbed in air, the evaporative cooling effect reduces the building’s cooling load. This provides significant energy savings in applications requiring both cooling and humidification.

Low maintenance

Wetted media systems are simple to operate, and recirculate potable or treated water through robust centrifugal pumps. The Vapor-logic controller manages the concentration of dissolved solids in recirculated supply water to minimize scaling and lengthen media life. When required, new media cassettes easily drop in to place.

Commonly used in data centers, industrial manufacturing, printing facilities, and applications using air-side economizers. Can be installed in air handlers and ducts.

Options: BACnet®, Modbus® or LonTalk® communication protocols

High-pressure system

The DriSteem High-pressure system provides evaporative cooling and humidification in multiple zones and in a wide variety of applications. Humidify to enhance indoor air quality, manufacturing process, material longevity. and comfort while taking advantage of the free cooling and energy savings inherent with this technology. The DriSteem High-pressure system handles every aspect of the application from the potable supply water source to the cooled/humidified conditions in the air handler, duct or space.

Energy-efficient

DriSteem’s High-pressure system uses heat already present in air to evaporate evenly distributed water droplets dispersed by the system, saving on energy costs.

Reduces cooling load

As atomized water droplets are absorbed, the evaporation causes air temperature to drop, reducing the cooling load. This provides significant energy savings when cooling and humidifying simultaneously.

Reduces water waste

The system’s Vapor-logic® controller monitors multiple conditions to modulate and control nozzle operation. This optimizes absorption and minimizes water waste.
