eTWIN PDE Dosing and Regulation System for two parameters The eTwin is a compact, easy-to-use equipment consisting of two dosing pumps and two parameters controllers designed to measure pH, Redox and Chlorine plus the temperature. Mainly conceived for pool’s industry, the dosing pumps are available either in peristaltic and solenoid versions. General Features • • • • • • Backlighted graphic display, 5 keys keypad, Manual dosing (ON-OFF) 0 ÷ 120 pulses / minute Proportional dosing by self-regulation of the stroke frequency Flow rate up to 5 l/h and pressure up to 6 bar Measures available: pH-pH; pH-Rx; Cl-Ph Measurement range: ➢ pH 0 ÷ 14 ➢ Redox: - 1000 / + 1400 mV ➢ PPM: 0 – 2; 0 – 10, 0 – 20 e 0 - 200 ppm ➢ Temperature 0 – 100 °C (PT100) Hysteresis Activation delay when switched on 3 programming menus: set-point, calibration, settings. 3 relays completely selectable: on timer mode (weekly/daily) or as an additional set-point (including the temperature). 1 additional relay dedicated to alarm signals 4-20mA output fully programmable. Inputs: level probes; flow sensor; PT100 probe; proximity switch Over dosing alarm Power supply: 230V 50-60Hz*; PVDF Pump head O-Ring: Viton® Valves: Ceramic Supplied with complete installation kit: ➢ Suction hose: PVC Cristal® ➢ Discharge hose: Poliethylene *other power supplies upon request All Etwins PDE are supplied with a standard kit made up of PP injection
