Spill Containment










Most products use venturi technology (the vacuum created by manipulating the speed of a stream of water) to mix chemicals with water. (l Run simulation) The incoming water stream is restricted by a nozzle, while the speed of the outgoing water is decreased by the inverted funnel shape at the bottom of the venturi. The result is a vacuum in the middle, where the chemical is sucked into the water stream. The amount of chemical introduced is regulated by interchangeable metering tips that restrict chemical flow into the water stream. The device does not require external electricity, batteries, pumps, or air pressure; it works from ordinary line pressure available in most buildings (15psi). Click here for animation


HydroGap II Air Gap Eductors

l

Air gap eductors function just like the standard eductor described above. However, before reaching the point of chemical injection, the water must pass through a 1" gap. (l Run simulation) Should the pressure in the incoming water supply drop while the air gap eductor is in operation, the mixed solution would be drawn backward into the gap, but chemical could not cross the air gap to contaminate the water supply. (lRun safety simulation)

This type of backflow protection is required in several areas.

E-Gap Eductors

l

E-Gap eductors function just like the standard eductor described above. However, should the pressure in the incoming water supply drop while the E-Gap eductor is in operation, the elastomeric sleeve would contract, opening access to the air vents and not allowing the chemical to contaminate the water supply. (l Run simulation)
