The IP Direct Fill® Technology uses a volumetric dosing pump, a switch valve to select vacuum, inert gas or rinsing solvent and a filling valve that directly connects the dosing pump via a short filling stud tightly to the filling hole of the hard case cell. No pre-chamber is used. The advanced valve technology allows the supply of all media to the filling stud (electrolyte, vacuum, inert gas, solvent).

Features 

• IP Direct Fill® with dosing pump (no pre-chamber) thus no gas solution into the electrolyte

• Rapid one-step filling maintains electrolyte composition

• Precise Filling with high accuracy:<=+/- 0,5% at high process stability

• Direct evacuation with down to 0,4 mbar absolute pressure in the cell

• IP Cell Protection® & IP High Pressure Fill® up to 40 bar

• The level of filling pressure, pressure curves and pressure cycles can be freely adjusted

• Incl. leakage test and pressure monitoring,  individual feedback full traceability of filling parameters

• Dosing quantity according to customer requirements

• Clean filling process without contamination of the cell surface
