CHLORINATION The Se-Tech Chlorinator accurately doses chlorine into low, medium and high pressure water systems. ​ Low-level, ongoing chlorination of a water supply is effective against bacteria, virus and other pathogens. These are often factors on farms with Water Exclusion issues, and in areas where water quality needs improvement. ​ Extremely low level, repeatable and accurate addition rates ensure safe, effective, low-cost water disinfection. ​ The Se-Tech Chlorination system uses a 3-stage process to ensure dosing consistency across a wide range of water flows. Water pressure fluctuations have no effect on the system. ​ Chlorine concentrations of between 5 and 50 parts per million (PPM) are easily acheived in this hands-off, safe injection system. The system first uses a peristaltic pump, which is externally controlled. 1. ​ ​ The pump loads a small amount of liquid chlorine into a calibrated cylinder. Chlorine dosage amount (relative PPM or parts per million) is controlled here. 2. ​ ​ The calibrated volume of chlorine gets pre-mixed with a standard quantity of water – and this premixed solution is loaded into the water supply via the 2-32 Se-Tech dispenser. 3. ​ ​ The (modified) Se-Tech Series 2-32 dispenser ensures accurate dosing. 4. OPERATION INSTALLATION AND BENEFITS The Chlorinator is suitable for installations with flows from 5 litres/minute up to 6000 litres/hour, and into pressures from “Gravity-feed” installations at 10 PSI to high-pressure runs up to 210 PSI. ​ The combination of the proven Se-Tech dispenser, together with a hands-free peristaltic pump – responsible only for loading, not for dosing accuracy – and calibrated chlorine pre-mix/addition station, provides accurate and repeatable dosing at extremely low levels, regardless of water flow/pressure and ambient temperature fluctuations. ​ Staff exposure to potentially dangerous chemicals is minimised, as chlorine is sucked directly out of its container – there is no manual mixing or handling of chemicals. ​ Installation is simplified, as the unit is powered by a low-voltage plug-in pack. ​ This means a certified electrician is not required to install the unit. The plug-in power pack is PAT (Portable-Appliance-Test) checked and certified before leaving our factory. ​ As with all Se-Tech products, Singh’s Engineering Services proudly designs, manufactures and services Se-Tech Chlorinators in Hamilton, New Zealand.
