TUNE-R-Ex

TUNE-R-Ex tight circular dampers are designed for use in potentially explosive environments. The dampers are equipped with manual control (marking H) or with preparation for a servo drive (marking M0). The dampers are manufactured in sizes 80 to 710 mm with a maximum pressure in the ductwork of 1000 Pa. The TUNE-R-Ex dampers for explosive environments can be varnished with any RAL tone of own choice.

As standard, the TUNE-R-Ex dampers are made of galvanized steel sheet with a rubber seal on the damper blade. The dampers are designed for operation at temperatures from -20 to 60 °C up to a maximum airflow velocity of 15 m/s. The conveyed air must be clean and free of chemical or mechanical impurities.

The dampers are designed in compliance with Group II category 2/-G for protection against ignition of gases belonging to explosion group IIC according to ČSN EN 13463-1:2009. The TUNE-R-Ex dampers meet the requirements of the directive ATEX 94/9/EC.

The TUNE-R-Ex dampers for explosive environments do not currently have a valid certificate - the production plant is working on its renewal and the dampers are undergoing the certification process again.
