The size of the orifice is based on the flow and pressure parameters determined by the designer. Generally, the higher the operating pressure, the better the quality of the foam produced. The better the foam quality, the more efficient the operation. Therefore, it is beneficial to utilize the highest operating pressure economically feasible. Specify flow rate and inlet pressure when ordering.
Deflectors are available in split or shallow configurations.
The split deflector is designed to accommodate most installations, and can be installed from outside the tank. Shallow deflectors are intended for use when the tank is fitted with a floating roof which may pass over the deflector, minimizing possible damage to the roof seals. Shallow deflectors must be installed from inside the tank. All Deflector mounting hardware is included. Chemical wash, rinse, and seal.
