High Heat Performance for Non-UL Regulated Applications

Elevated Temperature Option

Series 1500 with ET Option

ET Elevated Temperature Option:

  • Suitable for high heat environments where temperatures may reach as high as 300°F (149°C), and where UL regulated control dampers are not a requirement.
  • This option is ideal for dampers intended for use in back-up generator stations, where excessive heat may be an issue.
  • It is well-suited for test laboratory applications, wherever high-heat conditions may exist.
  • The Elevated Temperature Option is also a practical solution in mildly acidic applications, where Celcon bearings may not withstand environmental conditions.
  • Extruded silicone blade and frame seals used for dampers with the Elevated Temperature Option are extremely flexible and ensure minimal change in leakage rates as temperature increases.
  • Celcon and polycarbonate bearings are replaced with bronze-oilite bearings.
