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.
Elevated Temperature applies to the following Damper Series:
