Why it is done?
Thermography is done to save money - possibly big money. It does this by identifying temperature anomalies, and so helps to:
Find problems quickly and while equipment is operating under normal conditions.
Monitor and evaluate faults before they become critical.
Reduce downtime by avoiding equipment failure and so improves system reliability.
Plan targeted and therefore less expensive maintenance.
Avoid unnecessary servicing of components that are functioning correctly.
Ensure safety of staff and public from equipment failures as part of WHS commitment.
Improve risk management through planned preventative maintenance.
Comply with Insurance company requirements (sometimes obligatory in order to obtain cover), and possibly to gain a reduced premiums.
