Programmable Logic Controllers (PLCs) and Programmable Automation Controllers (PACs) provide reliable control over most complex machines, plant and processes equipment in use today. PLCs are often forgotten because they typically provide years of stable, fault-free service. However, having a service partner on-hand should the worst happen is critically important for maintaining plant uptime and meeting production targets.

Sulzer understands how disruptive a PLC failure can be. In these emergency situations, it is not always possible to send industrial automation equipment offsite for lengthy repairs. Sulzer offers a range of support solutions, from fast turnaround repairs to on-site automation and engineering support. These services help return your control systems to normal operation as soon as possible.

Sulzer has been accruing technical knowledge and experience for over 20 years and can offer fast, trusted advice on any make and model of controller. Many customers use our technical services daily to ensure the smooth running of their operations.

We offer a ‘no fix, no fee’ commitment on all industrial electronics services.
