Description
NAFFCO Proportioner is for use in fixed systems to introduce designed foam concentrate at a predetermined rate into the fire-water supply, over a varying range of foam solution demands. For example, where a number of discharge outlets may be required to operate individually or simultaneously.
There are 5 basic models with capacities from 40 GPM to 2400 GPM and each unit is factory-calibrated to suit proportioning rates of 1% or 2% or 3% or 6% of a specified foam concentrate.
The In-line Balance Pressure Foam Proportioner are used with positive displacement foam concentrate supply pump. The system controls accurately the flow of foam concentrate into the water stream over a wide range of flow rate and pressure.
The In-line Balance Pressure Foam Proportioning System is used for simultaneous operation of the multiple foam injection even with different pressures between the two injection point with a single concentrate supply line. Various sizes of in-line balance pressure proportioner can be combined to suit the flow requirement of each hazard area.
