Proactively Prevent Thermal Issues in Your Cabinet

Thermal management solutions for optimal cabinet conditions

Themal Management from nVent Hoffman

Incorporating thermal management within your industrial enclosures lengthens system life and increases control-line reliability. It's extremely important that system designers are aware of the temperature implications of their designs before implementation and, where necessary, take steps to reduce heat build-up inside enclosures. nVent Hoffman cooling solutions create optimal conditions for the reliable operation of electronic and electrical components in manufacturing controls, telecom equipment, data networks, and other vital systems.

Thermal-Management Challenges

Extreme temperatures can have these effects on industrial control equipment:
  • Catastrophic failures can occur
  • Silicone material properties can change
  • Drive performance is de-rated
  • I/C-based devices may experience intermittent fluctuations in output and voltage migration
  • Mean Time Between Failure (MTBF) decreases exponentially
The costs when a line goes down due to temperature extremes are:
  • Productivity losses
  • Increased labor costs
  • Increased scrap
  • Opportunity losses
  • Component costs
  • Missed ship dates
  • Decreased customer satisfaction
