LiSEC – longevity par excellence

The LiSEC After Sales Service department provides modifications that extend beyond normal replacement parts sales

Glas Müller AG is a classic family-owned glazier’s workshop in Switzerland, which processes the full spectrum of glass products for buildings with around 30 employees at its site in Schlieren.

With a proud 36 years in operation and full production capability, the LiSEC GTI insulating glass machine supports the production of insulating glass at the workshop in Zurich and is primarily used for repairs and insulating glass for cat flap holes.

Mr Stöcklin, Managing Director of Glas Müller, is thoroughly impressed with the LiSEC machine, “The machine has not caused us any major problems at all to date. A few spare parts have been replaced over the years and the washing machine has been exchanged once. But all in all, it has been in constant use. And we want it to stay that way.” That is why the company recently requested a general overhaul from the LiSEC After Sales Service team. “This machine is worth its weight in gold, in particular when it comes to niche products such as insulating glass with holes for cat flaps, and is a credit to the LiSEC name,” says Mr Stöcklin.


Glas Müller also intends to optimally realise future strategic goals with the LiSEC GTI insulating glass machine. The company will continue to focus on niche products with rapid delivery times and tailored adaptations directly for the customer. To ensure these goals remain feasible, the machine must also be serviced and maintained accordingly – and not simply supplied with spare parts.


In addition to this special offer of a general overhaul of a vintage insulating glass unit from LiSEC, the company is also offering targeted conversions and improvements to the systems – in particular for machines built after 2000 – which can increase the service life of many machines. The LiSEC After Sales Service department provides modifications that extend beyond normal replacement parts sales. This includes PC upgrades, drive modifications, and similar modifications/improvements.

A preventive replacement of obsolete elements ensures the supply of replacement parts and service for the long term. This ranges from upgrades to drives using industrial PCs to the complete replacement of the machine control system. The advantage is modernisation of the machines at low cost, compared to purchasing a corresponding new machine. The solid, basic machine properties remain preserved.
