Cosaf History

Who we work with


Our Process

To understand your problem we invest our time on site with you at the heart of the issue. Our experienced engineers are ISO 9001 accredited and trained in the art of attention to detail and we utilise the latest technologies to assist design and visualisation.

Survey & Assessment

We often use thermal imaging cameras and laser scanning to build a perfect picture of your space. Laser scanning of industrial premises to provide a 3D working drawing is crucial for future development of the space. We are Revit and BIM ready to coordinate the whole building services requirements of mechanical and electrical as well as future proofing the service and maintenance requirements.

The Solution

More often than not there are a number of engineered solutions to fix the problem, we engage with you to work through the options and develop the best solution based on your objectives.

Responsible Design

Our engineers are trained through Cosaf programs to be innovative thinkers and where possible use sustainable 21st century materials, better performing equipment and to design health & safety risks out from the beginning.

Service & Maintenance

On completion of the installation, our service and maintenance division will offer a comprehensive after care solution. Our national network of engineers can ensure a reaction time to suit your needs and ensure your investment is cared for.

Energy Monitoring

Taking energy monitoring to the next level. Cosaf energy monitoring solutions ensure your major plant items are running at their optimum performance and show you clearly on a dashboard the consequences of a blocked filter in terms of money spent in lost efficiencies. We are interested in knowing what your plant items optimum running costs are and keeping them there, as opposed to just knowing what it costs to run.
Our monitoring systems provide recommended filter replacement frequencies, component failure prediction and fault diagnostics to ensure your plant items stay running and running at their most optimum, with little to no down time keeping your business moving and productive.
