From installation and commissioning through preventive maintenance and repair, SLI provides the technical support your LNI Swissgas, Nel Hydrogen, and NXT Power equipment needs to stay running.
Whether you need help getting a new generator online, keeping it running at spec, or diagnosing an unexpected fault, SLI has you covered.
New equipment performs best when it’s installed correctly from day one. SLI coordinates installation for all products we sell — verifying utility connections, configuring operating parameters, running startup tests, and confirming output meets specification before handing off to the customer.
Scheduled preventive maintenance extends equipment lifespan, maintains output quality, and catches developing issues before they become failures. SLI offers PM services for LNI Swissgas, Nel Hydrogen, and NXT Power equipment following manufacturer-recommended intervals and procedures.
When equipment faults, every hour of downtime has a cost — instrument runs on hold, experiments paused, or industrial processes interrupted. SLI provides fault diagnosis and repair for all products in the SLI portfolio, with direct manufacturer technical escalation for complex issues.
Not every issue requires a site visit. SLI provides responsive phone and email technical support for application questions, instrument compatibility concerns, operating parameter guidance, and first-line troubleshooting — helping you resolve issues quickly without waiting for a field engineer.
SLI provides installation, maintenance, and support for every product line we distribute — backed by direct manufacturer relationships for each brand.
