Nitrogen gas generators now supplied by Bystronic for fibre laser cutting machines

Share this on social media:

Swiss firm Bystronic is now supplying generators of nitrogen gas for its fibre laser cutting machines.

Nitrogen is conventionally supplied in tanks or cylinder bundles for such machines, however this setup can run the risk of the gas running out, which leads to expensive downtime for fabricators until new supplies of gas can be delivered.

This issue can be avoided, however, if the fabricators instead generate their own nitrogen, as can be achieved using the ‘NitraCut’ systems now supplied by Bystronic from South African firm NitraLife.

‘What we have found, is that for a busy fabrication shop, by generating their own nitrogen, the cost of a NitraCut generator can be amortised within the space of a year – or less in some cases,’ explained Tom Sowry, managing director of NitraLife. ‘After the NitraCut has paid for itself, the owner of the fabrication shop essentially continues to have a free supply of nitrogen.’

He reported that while initially fabrication business owners have been hesitant about acquiring a NitraCut system, their feedback has always been excellent – citing the example of a leading steel processing company which operates six fibre lasers.

‘We initially connected a NitraCut to one of their smaller Bystronic machines,’ he said. ‘After a period, the cost-saving convenience of the NitraCut became evident. Recently, this company purchased three more NitraCuts, which are connected in parallel to supply the large gas volumes needed by the company’s 10kW ByStar Fiber laser.’

The generators are particularly suited to fabricators in locations where conventional gas supplies are either erratic or unavailable. For example, the first Bystronic BySprint Fiber 3015 was recently purchased by a company based in Harare, Zimbabwe, where the supply of gas can be uncertain. The Bystronic laser was supplied with its own NitraCut generator, which has allowed the company to continue cutting steel without interruption.

NitraCut generators are also suited to the automated factories of Industry 4.0, as supplying an uninterrupted flow of nitrogen to automated fibre lasers enables their operation to continue with minimal human intervention or skilled supervision. ‘As the generator has no moving parts, it is also absolutely reliable and requires minimal and infrequent maintenance,’ Sowry confirmed.
