Heavy Duty Flue Gas DAMPERS
Applications: evacuation of non-grain flue gas, hot air and fresh air circuits
e.g. for Power Stations, Gas Turbine Plants, FGD Plants, DeNOx Plants, Cement Works, Waste Incineration Plants and other industrial installations.
thenex GmbH is optimizing its engineering and on-site services in
respect to flue gas dampers.
As such, we are in the position to cope with even the largest and
complex damper contract in an efficient and timely manner.
thenex and its partner will conduct the entire process from technical
consulting, design and engineering up to manufacturer and installation
including commercial execution – based on your specific
needs and process requirements.
The supplies and services cover all process equipment
required:
• for shut off flue gas ductsAny process-specific challenge such as high temperatures or extreme temperature cycles, fluctuating pressure or high dust loads and corrosive attacks can be addressed by corresponding flue gas dampers/valves in practically every industrial installation.
• for divert or control of flue gas flows
• for maintenance of process equipment
during plant operation
• to bypass isolated process equipment
• to enable a controlled part-load operation
• to protect process equipment at failure
• due to fast opening or closing dampers

The application of sensors with terminal chamber connection is commonly used in the Food & Beverage industry. In order to profit from the advantages of the uprox®+ Factor 1 sensors, the uprox®+ Wash-Down series is now also available with extremely flexible terminal chamber connection.
The sensor allows a straight or 90° angled cable routing by simply twisting the cover. The removable terminal strip with convenient and vibration resistant cage clamp technology enables simple and quick connection of the sensor. LEDs in the terminal chamber inform the user about the switching status.
The new uprox®+ sensors with cage clamp technology are available as M12, M18 and M30 versions, fulfi l all requirements of food safety and are FDA conform.
V4A stainless steel housings and a special sealing guarantee reliable protection against aggressive cleaning agents and high pressure cleaning methods.
Like all uprox®+ Factor 1 sensors the new terminal chamber version
guarantees maximum freedom with regard to development of
machinery and systems. Highest switching distances and extreme
flexibility with regard to mounting, are only two outstanding advantages
of this sensor type – especially when considering stainless steel
targets which commonly occur in the Food & Beverage industry.
