SHIELD Low Expansion Branch Pipe is air aspirating type handline nozzle designed to maximize mobility and firefighting capability. The aspirating design makes the nozzle superior in performance by maximizing foam expansion and drainage time.

When using handline proportioner/ in-line inductors as portable devices a pick-up tube is provided to draw foam concentrate from the portable foam containers.

SELF INDUCTING BRANCH PIPE

SHIELD self-inducting foam type Branch Pipe designed to meet the long range performance. There are eight models with flow of 225 LPM and 450 LPM. This nozzle is an air aspirating handline nozzle designed to maximize mobility and firefighting capability.

The self-inducting feature eliminates the need for a separate proportioner, which allows foam operation wherever water supply is available. The fully aspirating design provides superior performance compared to nonaspirating nozzles by maximizing foam expansion and 25% drainage life.

SHIELD Rim Seal Foam Pourer consists mainly of Foam Maker, a windshield and deflector. The Rim Seal Foam Pourer is designed to deliver fully aspirated foam directly to the annular seal area of open top floating roof tank. The Rim Seal Foam Pourer is used for one of the most common applications of protecting tank seal in vertical liquid storage tank with internal floating roof with low expansion foam system.

The application of aspirated foam is on the basis of the risk comprising the area in the annular ring between the rim of the floating roof and the tank shell. The Foam system design guidelines generally used are in accordance with NFPA 11 standard. Rim Seal Foam Pourers are defined by NFPA 11 as Type II discharge outlets for delivering the low expansion aspirated foam to the seal.

The Rim Seal Foam Pourer is an air aspirating foam generator connected to the foam maker to deliver the aspirated foam gently into the tank seal area. The rim seal foam pourer covers a wide range of foam solution rates from 41 GPM to 207 GPM at 50 to 100 psi inlet pressure.

Portable Monitor is used in the place where operator is difficult to access like hazardous storage, outdoor oil tank, gas storage tank, chemical factory. Also equipped in the fire truck to deploy during fire fighting operation at the hard to access area.

Monitor is light weight for easy transportation to required area. Foldable type legs can be folded by one simple touch for quick transportation.  Vertical movement is 90° (85° above and 5° below horizon­tal) and horizontal movement is a full, continuous 360 (hand wheel remains stationary), grease-zerk for easy lubrication.

SHIELD  Monitor mounted on Water Powered Oscillating Unit, transforms the manual monitor into an oscillating monitor. The unit is suitable for use in high risk areas such as tank farm facilities, aircraft hangars, offshore, refineries, chemical plants, and heliports.

The monitor possesses several design features that provides ease of operation, minimum maintenance and resistance to corrosive environments.  A water drive wheel is connected to a double reduction gearbox drive and oscillating mechanism. To operate the drive wheel, a small quantity of flow is diverted from the monitor inlet. The monitor requires no external wiring or hydraulic control for operation.

The minimum operating water pressure of the oscillation mechanism is 3.5 kg/cm² The flow of water through oscillation mechanism is 42 LPM at 3.5 kg/cm² and 60 LPM at 7 kg/cm² of water pressure. The design ensures to prevent jet reaction forces from affecting the horizontal and vertical position of the monitor during operation.

The vertical angle of elevation and horizontal arc of oscillation is field adjustable and can be set and locked in position. The monitor can be set to oscillate over a range of 0°-120° and the oscillation arc can be set anywhere within the 360° field of operation. The unit is equipped with a garden hose test connection. This allows functional check of the oscillating mechanism without system flow.
