Dispensing for Batch Dyeing

O.T.D. - On Time Volumetric Dispenser

AREL Volumetric On Time Dispenser is a high precision, high capacity dosing system for liquid products.
The dispenser measures programmed quantities of the liquid and forwards it to a selected destination.   

The system combines a high capacity variable speed dosing pump and high precision flow measuring device, controlled by a PC based industrial controller.

The delivery valves are installed on a common batteries. 

Carefully sized distribution pipe line, with air actuated three way valves, is normally used to connect the dispenser to the destinations, ensuring an efficient and very simple layout. 
Very small quantities of water are required to flush the line.

A unique algorithm controls the variable speed dosing pump, enabling high capacity and high accuracy/resolution, for large, as well as, for small dispensing quantities.

Two Operation Modes are available:

1. Operator Menu-Driven Mode:
   The operator keys the requested chemical or recipe and the destination.
   When the start key is pressed, a dispense cycle starts. When completed, the controller will prompt the operator to key in the next dispense.

2. Supervisory PC Computer Integrated Mode:
   The dispenser is part of the integrated dye house control. Based on the preparation step in the currently processed batch, the central computer sends the required chemicals and quantities to the dispenser controller. The central computer maintains a queue of the dispenses required by the machines at any given time.
   When the dispenser controller confirms that a dispense to a specific machine is completed, the next required dispense will be sent from the central computer.
