PERFORMANCE CHARACTERISTICS
Type DES 3000-1F-STS-1 Ton Dry Emergency Scrubber is designed to handle an accidental leak of
chlorine from a fusible plug in an overfilled (2,350 pounds) one-ton chlorine container. The
chlorine-laden gas will be drawn at the top of the tank, pass through the Type STS dry media
where the chlorine will be scrubbed by the media bed. The system will provide a 1-1/2" W.C.
draft which will be available for duct losses. Removal of chlorine will be better than that
required by the US Uniform Fire Code or 5 ppm maximum at the point of discharge.The
scrubber will be able to neutralize the entire contents of an overfilled one-ton chlorine
container meeting the latest requirements of the NFPA 1/UFC.
The chlorine leak from the fusible plug can be as much as 437 pounds/minute or 2380 scfm. The
system has been designed for a capacity of 4000 cfm clean air/3000 cfm chlorine laden air. This
assures a negative pressure in the room for clean air flushing. The time to pull down the gas
volume of the room to 1 ppm, after the cessation of the chlorine release, is approximately 45
minutes per 10,000 cubic feet of room volume.
De Nora Water Technologies, Inc. has performed a certified test of the emergency gas scrubber
system with a chlorine release while meeting the allowable NFPA 1/UFC chlorine discharge
concentration limit. DE NORA guarantees that the proposed scrubber will meet the NFPA 1/UFC
allowable discharge chlorine limit.
