MTOWER 2CH
CONTROL INSTRUMENT
MTOWER 2CH control instruments are a series of fully feature control systems for cooling towers.
They manage simultaneously two parameters: pH or ORP or chlorine, conductivity or inductive conductivity (to specify on order) and temperature. Probes are not included.
They can be remotely controlled through the exclusive web management system ERMES.
MTOWER 2CH models have: widescreen LCD display, easy control by encoder wheel, current Feed & Bleed display, local & remote control, simultaneous multiple view for probes reading, N.O./N.C. levels selection, inhibitor proportional dosing to WM1, WM2 or both, “biocide 2” proportional dosing to water meter, programmable biocide feed (max 1 per day), selection stop/no alarms for high/low feeding, working mode auto/manual/stop, permanent data storage with system log, stand-by input, mA output (optional), different working modes (on/off, impulsive proportional, proportional PWM and fixed PWM), pre-bleed (educed water system conductivity before biocide dosing), blow down (discharge control on conductivity values), lockout (discharge valve locked for a settable time, after biocide dosage), timeout (maximum discharge valve opening time), programmable delay at dosing start-up (up to 99 minutes), PT100 temperature compensation, alarms and log report (hourly, daily, weekly, monthly).
