ET
Elevated Temperature 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.
