11 Litre DI Vessel Complete (8"x17")


This is the ideal size DI Vessel if you are filling your tank direct from tap pressure. Many suppliers sell their customers small DI Vessels but fail to advise them that volume versus flow rate is key to resin performance. TDS levels can rise when the flow rate is too fast for the volume of resin. To avoid this happening completely we recommend that you only use a di vessel 11L or above.

For price per litre this is one of the cheapest DI Vessels on the market whilst being of exceptional quality.

These are brand new and are not reconditioned.

Price includes delivery to UK Mainland (ex. Scottish Highlands)
