A state of the art programable microchip controls the generation of low frequency signals by the two antennae or areials wrapped on the exterior of the pipe. These radio signals are transmitted through the pipe and into the water flow. This changes the crystalisation characteristics of the hardness salts in the water thereby inhibiting the build up of hard damaging scale. As the calcium and magnisium is not actually removed the water maintains its health giving qualities Liff Wrappa Scale Inhibitor- Control box height 150mm width 80mm depth 50mm- 240v 50Hz single phase (transformed to 12v internally).Supplied with:1x flying lead (2m) with a fused 5a 3 pin plug2x leads (2m each) to coil on pipe and connect to control box4x ties to secure coiled wire on pipe and one at each end4x screws to secure control box to wall Benefits of the Liff Wrappa Scale Inhibitor - One programmable unit for 15mm 22mm 28mm and 35mm pipework - No plumbing or down time- Fit to hot or cold water pipes- Low running costs- Existing scale removed- No maintenance
