Reduce down-time, equipment failure and energy use


Running manufacturing automation systems at high temperatures will have a major negative impact  on the system’s performance and reduce its service life.  By not keeping their drives at or close to their  optimum operating temperature, manufacturers  risk huge consequential costs when the  production line grinds to a halt as a result of system failure.

A typical electrical component’s life expectancy is  approximately halved for every 10 °C increase in  its ambient temperature. Controlling the temperature  within enclosures is therefore critical for manufacturers  to avoid premature component failure and the  interruption to production if the automation  system falls over.

A Rittal RiAssure3 survey will identify the likely risk  of a system overheating which could lead to equipment  tripping or failing. The survey will review any  existing cooling solution and determine how suited it is  to that particular working environment. It will then provide  recommendations around remedial action – for example,  changes to the system’s service and maintenance regime  to help improve its efficacy or the need to invest in  different climate control technology.

A basic checklist for reviewing climate controls in a  manufacturing automation system:

  • Equipment tripping or failing due to high temperatures which  is having an impact on production lines, in that they are either  slowing or stopping completely
  • Enclosures which feel hot to the touch
  • Enclosure doors regularly left open or a need for large fans  blowing into the panels as the weather improves
  • An inadequate chilling of process fluids which results in production down-time
  • Or simply the opportunity of a health check for the cooling  solution

As summer approaches, ambient temperatures will rise which  could push operating temperatures beyond the limit of the  existing equipment, so tackling the issue now could be a  timely call.
