August 4, 2006 Foam 73a 1. DESCRIPTION Hi-expansion Water Powered High Expansion Foam Generators are designed to expand foam solution into millions of tiny stable bubbles. Expansion rates of 350 to 600 gallons of foam for every one gallon of foam solution can be achieved depending on the generator selected, solution flow rate and operating pressure. This expansion ratio provides the optimum combination of expansion, wetness and water retention needed for fire performance. A. Features Five different models available. No outside source of power required only the foam solution under pressure. UL Listed ranges from 2,500 cfm to 28,500 cfm depending on unit selected and inlet pressure. Largest UL Listed operating pressures between 40 psi and 100 psi. Easy installation with units capable of being mounted and used in the horizontal or vertical configuration. Inlet gauge tap for system testing. Foam solution piping and discharge nozzle are of open design allowing passage of particles up to 1/4 in diameter without use of a strainer. 2.

Foam 73b August 4, 2006 B. Typical Hazards Typical hazards where High Expansion Foam Generators may be used to supply fire protection are: 1. Aircraft hangars. 2. LNG tank farms/loading facilities. 3. Flammable liquid drum storage areas. 4. Hazardous waste storage facilities. 5. Shipboard engine rooms, bilges and holds. 6. Roll paper warehouse. 7. Chemical storage facilities. 8. Flammable liquid packaging areas. 9. Cable tunnels. 5. OPERATION The high ratio of expansion of the high expansion generator is achieved by spraying foam solution into a stainless steel screen and forcing the solution through the screen with a high velocity air stream to produce a mass of foam bubbles. A water motor driven fan, powered by the foam solution used to create the high expansion foam, is used to produce the required air stream. This allows the water powered high expansion generator to be a self-contained unit requiring no external power for operation. With the continuous flow of the foam solution and movement of air through the screen, large volumes of expanded foam can be generated. 6. INSPECTIONS, TESTS AND MAINTENANCE NOTICE: The owner is responsible for maintaining the fire protection system and devices in proper operating condition. For minimum maintenance and inspection requirements, refer to recognized standards such as those produced by NFPA, LPC, and VdS which describe care and maintenance of sprinkler systems. In addition, the Authority Having Jurisdiction may have additional maintenance, testing and inspection requirements which must be followed. WARNING: Any system maintenance or testing which involves placing a control valve or detection system out of service may eliminate the Fire Protection of that system. Prior to proceeding, notify all Authorities Having Jurisdiction. Consideration should be given to employment of a Fire Patrol in the affected area. Inspections: It is imperative that the system be inspected and tested on a regular basis. Refer to NFPA 25 for the standard requirements. The frequency of the inspections may vary due to contaminated or corrosive water supplies and corrosive atmospheres. In addition, the alarm devices or other connected equipment may require more frequent inspections. Refer to the technical data, system description, applicable codes and Authority Having Jurisdiction for minimum requirements. Prior to testing the equipment, notify appropriate personnel. 7. AVAILABILITY The Hi-Expansion Foam Generators are available through a network of domestic and international distributors. See the Viking Corp. web site for closest distributor or contact The Viking Corporation. 8. GUARANTEE For details of warranty, refer to Viking s current list price schedule or contact Viking directly.
