REPI offers a range of internally engineered dosing units, able to improve the quality of the colouring process and to offer maximum dosing precision of liquid colours and additives.
AUTOMATIC COLOUR FEEDING SYSTEM
The system enables the in-line dosing of colours and additives to PU systems quickly and easily by means of U2011 dosing unit engineered by REPI.
U2011 is equipped with a gear pump, sized according to the dosing process, connected to a control unit managing the dosing process parameters. The unit self-adjusts dosing according with the flow of polyol/isocyanate variations during the filling process.
The system avoids:
• colour contamination of the mixer
• the need of a dedicated mixer for each coloured production (e.g. black dispersion)
• scrap generation and complex mixer cleaning process
APPLICAZIONI
• SYSTEM HOUSES: colour is added just before filling drums
• PU components: colour is added before production tank
VANTAGGI
• More colours can be achieved by simply changing or cleaning the pump or adding more units
• U2011 is portable and can be moved and connected to different filling stations
• No colour/additive contamination of mixers
• No need of dedicated mixers
• Limited scraps and easy cleaning between one production and another
COMPONENTI
• U2011 dosing unit with gear pump
• Load cell
