Description
The high pressure Select Doser for water treatment.
This versatile doser can be used as a proportional doser taking a pulse from a standard water meter, or pulses from standard Dosing Solutions flow sensors. Dosing into line pressures of up to 5 bar (70 psi), it is the ideal doser for water treatment.
This is the upgrade version of the Select-360. All of the normal dosing options and ratios are easy to select on-screen as will all other dosers from Dosing Solutions Ltd.
THE SELECT dosing system has been designed for use in agricultural and other situations where products are required to be dosed into water proportionately to the flow.
THE SELECT-380 incorporates a powerful motor and gearbox to give reliable and trouble-free performance.
USING A peristaltic pump has the advantage that dosed products, regardless of how aggressive they are, only come into contact with the pump tube, not the working parts of the pump. Removing the old tube and fitting the new one effectively cleans and renews the pump.
THE PUMP tubes have been tested for stability and durability against most commonly used dosing products including acidifiers and chlorine. If in doubt, contact Dosing Solutions Ltd or your Distributor.
Proportional Dosing The choice of dosing ratio is selected from the screen controls. Details of water flow rate and water consumption is also shown on the screen.
All normal Select Doser program variations are available for the 380.
Pump tubes should be changed regularly. This is a simple procedure which involves sliding up the blue pump head cover, unclipping the old tube and clipping in the new one.
This is the ideal doser to use for water treatment when water line pressures are relatively high, and the dosed product requirement is low.
