Thermal Surveys

Thermal surveys are used to examine electrical circuits and components for loose connections, arcing, overloads or unbalanced phases. Though invisible to the naked eye, such electrical faults can pose a significant fire risk. 

ISS thermographic surveys are carried out by qualified thermographers who are able to quickly and easily bring these problems to attention before they escalate to the point where they cause a fire or an electrical fault that leads to plant downtime and loss of production. Our engineers are experienced in the inspection of a full spectrum of electrical systems, from HV/LV switchgear to busbar cabinets and control panels, fuse boards and motors.

SCADA System Configuration & Maintenance

ISS developers are able to configure Prodigy SCADA systems to give powerful, value-for-money systems tailored to the process, its environment, and the level of management data required. Companies from all kinds of industry sectors have benefitted from our innovative solutions for the improvement of control, quality, traceability and process visibility, and the simplification of record keeping, recipe handling, alarm functionality and operator interfaces. To find out more about SCADA system configuration and maintenance from ISS, please get in touch on 01943 602001.

Instrument Upgrades and Refurbishments

Instrument upgrades or refurbishments are a cost-effective way of improving accuracy and control, and often give better operator visibility and connectivity. We provide a range of modular instruments that allow you to minimise spares holdings whilst maximising spares coverage, and which enable your local distributor to react much more quickly to breakdowns. You can find some examples of recent upgrades/refurbs carried out by ISS engineers on our website. To discuss your requirements with an expert, just give us a call on 01943 602001.
