Construction of the Suprion Scale Prevention Device
All models of Suprion share the same construction ... only the size and fitting are different.
Plastic pipe (Epoxy FRP)
The plastic pipe is smooth inside, and so does not impede the flow of water. However, there is enough friction to generate static electricity. The Epoxy FRP has excellent resistance to corrosion and pressure, and no harmful substances leach into the water.
Electrodes
The Suprion contain two electrodes, one carbon, and the other aluminium. The Suprion's electrodes are outside the plastic pipe, and do not come into contact with the water. This prevents corrosion of the electrodes, a significant problem with other devices.
Casing
The metal casing completely encloses the electrodes and the plastic pipe, creating an impermeable seal.
Joints
Suprion devices designed for smaller pipes up to 40mm (1½"), are fitted with screw or olive couplings. The larger Suprion models from 50mm (2") to 450mm (18"), are flanged and supplied with the corresponding welding flanges.
Earth terminal
When a Suprion is connected to metal pipework at one or both ends, it does not need to be grounded to earth. For installations where both ends are connected to plastic pipe, a Class 3 Earth Terminal is provided. The earth terminal is located towards the downstream end, aiding correct installation if the flow arrow label is missing or illegible.
