WIDE RANGE PROPORTIONER
NAFFCO Pressure 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.
The NAFFCO Wide Range foam proportioner is designed to provide amount of foam concentrate to match minimum percentage to mix with water stream over a wide range of flows. These proportioner neither require any pressure restricting devices nor electrical connections & are purely mechanical based.
- UL Listed/FM Approved
- Corrosion resistant bronze(WRC-B)/ stainless steel construction (WRC-S).
- Custom flow and pressure options available.
- Optional threaded or flanged end connections
- Size 2.5inch to 10inch proportioners available
