eTWIN PDE

Product catalog summary

Overview
The eTwin PDE is a dosing and regulation system designed for measuring and controlling two parameters, specifically for the pool industry. It includes two dosing pumps and controllers for pH, Redox, Chlorine, and temperature measurements. The system is available in both peristaltic and solenoid versions.

Key Features

Backlighted graphic display with a 5-key keypad.
Manual dosing capability with 0 to 120 pulses per minute.
Proportional dosing through self-regulation of stroke frequency.
Flow rate up to 5 l/h and pressure up to 6 bar.
Measurement ranges: pH (0-14), Redox (-1000 to +1400 mV), PPM (0-200 ppm), Temperature (0-100°C).
Includes hysteresis and activation delay features.
Three programming menus: set-point, calibration, and settings.
Three selectable relays for timer mode or additional set-point, plus one relay for alarm signals.
Fully programmable 4-20mA output.
Inputs for level probes, flow sensor, PT100 probe, and proximity switch.
Over dosing alarm and power supply of 230V 50-60Hz.
PVDF pump head, Viton® O-Ring, and ceramic valves.
Supplied with a complete installation kit including suction and discharge hoses.
