HVAC Optimisation
HVAC systems can be optimised to maintain the required environmental conditions while minimising the energy demand. Sirus can carry out a detailed survey of the HVAC setup at a facility, including airflows, room-pressure profiles, duct pressure profiles, control strategy, room conditions and activities.
The results are analysed and an action plan developed to optimise the HVAC system operation. Improvement measures are ranked based on potential energy savings, impact on operations and capital cost.
HVAC Maintenance
Sirus provide maintenance for systems we have installed and for systems previously installed by others. Through the use of thermal imaging, we can detect problem areas before they become serious issues. The infrared camera can be used to scan a range of electrical and mechanical equipment to get an instant picture of potential problems.
Buildings can benefit greatly from HVAC planned preventative maintenance (PPM) programmes. Sirus can draw up suitable PPM plans to reduce costly repairs and unplanned capital expenditure on boilers and other HVAC equipment and ensure a healthy indoor climate is maintained.
Service Management Software
Sirus uses cutting edge Service Management Software for servicing and maintenance of our customer’s assets. The management of the engineers’ time sheets is also a key part of the solution, which is designed to automatically issue engineers with tasks and update all forms and reports on the system.
The software includes an interactive web-based platform upon which all our Customers can track the progress of maintenance and call-outs, request quotations, quantify equipment downtime and complete historical service analysis.
