Protechnis provides Safety Instrumented Systems (SIS) and explosion protected electrical systems for hazardous areas. Our typical systems are bespoke in nature and are usually developed as a solution to a particularly difficult or unusual problem. Our recent activities have included SIS for both onshore and offshore applications and have included environmental control systems for use in extreme temperatures /environments. We also undertake systems upgrades to replace obsolete equipment which may include a need for reverse engineering of systems typically where this involves the replacement of legacy systems with limited engineering information. We also undertake installation, build and maintenance in tight shutdown windows.
