High-pressure humidifier also provides adiabatic cooling
JS Humidifier’s Condair FF2 high-pressure spray humidifier can deliver up to 1080 kg/h of moisture to a duct or air-handling unit. It is said to be ideal for AHUs with multiple humidification and adiabatic-cooling elements, as a single pump station can feed nozzle grids in up to four different ducts. At maximum output, power consumption is 3.2 kW — with the potential to deliver 745 kW of adiabatic cooling. RH can be controlled to ±4%.
The Condair FF2 consists of a high-pressure pump station that feeds water to a grid of atomising nozzles inside a duct and spraying towards a droplet eliminator. The airstream absorbs the water mist over a distance of about 0.8 to 1.3 m, with the remaining droplets removed from the airstream by an evaporative matrix. As water flows down this particle-free matrix it is absorbed by the air passing through it to increase humidification efficiency and reduce waste water.
The pump station can feed nozzle grids in multiple ducts, so incoming air can be humidified and exhaust air cooled adiabatically so that an energy-recovery system can be used to pre-cool incoming air. This makes the Condair FF2 more economical than using more than one humidifier to achieve the same result.
The pressure drop on the airstream is about 45 Pa. The spray nozzles are of stainless steel with a ceramic insert to give a wide spraying angle. Drain and flush cycles ensure that water does not remain in the system when it is not operating.
