BT Series - MA/AD Solenoid Dosing Pump

The eControl series of controllers have been designed and developed to be used in wellness centres, domestic and public swimming pools.
The controllers use galvanic isolated micro-processors protecting the measured readings from the application environment.

The principal functions performed by the eControl are:

Eselect B4

eSelect B4

In reference of the last technology in electronic field we have built the B4 controller to measure the main parameters in the water treatment applications. It is possible to connect the new controller to an Ethernet LAN to control all parameters and storage all data. We have decided to use a 7” coloured display touchscreen to improve the view, the user-friendly setting and display the graphic of the time-measure.

The main technical characteristic of the new B4 are the following:
