All over the World only the Lisec gas filling systems offer the outstanding advantages of fully automatic gas filling of double and triple i.g. units and of off-set units with up to 4-steps all around whether with or without georgian (muntin) bars - all in one working cycle. Even shaped units or special combinations with cast glass or very thick glass mean no problem at all.

The Lisec gas mixing/metering technique has command of the optimized use of freely selectable gas mixtures and the laminary gas filling system provides an optimum filling ratio, shortest cycle times even at long unit sizes – all with minimum loss of gas.
