Product Description

Our box type removable insulation jackets for steam traps can help you save significant amounts of energy and protect your employees from workplace accidents.

The surfaces of steam traps typically get quite hot, and radiate away valuable heat. For example, a small typical 1” un-insulated steam trap station loses more than $ 200.00 per year in wasted energy. The steam trap portion of this station usually accounts for 40%-50% of the trap station loss.

Furthermore, if the steam trap is extremely hot it may pose a safety hazard if left completely uncovered. While not every type of steam trap can be insulated the same way, or at all, insulation remains a no-brainer for many steam traps. However, more often than not, steam traps that could be insulated simply never are, and needlessly waste energy as a result.

Thermaxx box type insulation blankets fit many common inverted bucket and float and thermostatic steam trap models from leading manufacturers including:

  • Armstrong
  • Spirax Sarco
  • Hoffman
  • Barnes & Jones
  • and more
