We've helped people in the past and they've said some nice things

During the 16 years in which Op-tec has worked on our sites, they have proved to be an outstanding and dependable performer, providing a first-class support package. We are confident in their expertise and abilities.

Keith Leonard
Head of Maintenance | Veolia Environmental Services (UK) Plc

DENSO Manufacturing UK Limited have been using Op-tec Systems for over 16 years now, for projects of varying size and complexity. As a company Op-tec falls into that small niche market of being able to integrate 'Information Technology' into 'Automation'. It is in this aspect where I have found Op-tec Systems to be second to none.

Software Engineer - Machinery Engineering | DENSO Manufacturing UK Ltd

Op-tec has assisted Perenco in the supply of engineers with specific project deliverables, which they always achieved ahead of schedule and within budget. Their staff were dedicated, well thought of within Perenco and were often requested to return for extra project work and occasionally for Operational Support. Op-tec provided an efficient service, always there when we needed help, were ace at reprogramming the RS3 system and also sourced spare RS3 hardware when required. Their staff were always helpful, however late in the evening it was.

Op-tec have provided technical support to us on a number of occasions. The in depth knowledge and flexibility of their staff have been key contributors to the success of recent projects. Op-tec have also provided training, particularly around Rosemount System 3, which has proved to be invaluable. We are looking forward to working with them in the future.

Op-tec's professional approach, attention to detail and excellent programming skills, coupled with an extensive all round process engineering knowledge base, have been a key factor in our association.
