Inlet bells, fan rings, FRP cooling tower elements
Fan rings
They have the same parameters as fan stacks, but are designed for operation in forced draft systems (air-cooled condensers). By default, they can be delivered with protection grid attached to the lower flange of inlet.Design, shape and geometrical dimensions of new fan casings are optimized during design stage in order to secure the highest endurance parameters. The influence of impeller blades on fan ring’s wall is analyzed. On that basis, appropriate technology is being developed – it prevents from the vibrations during the operation of fan.
Inlet bells
Inlet bells are another key product of WENTECH. They are designed for optimization of airflow parameters and secure maximum efficiency of a dry cooler.Basic parameters:
- Made of FRP composites
- Single layer structure. Segmented design – easy transport and quick assembly on ground level or under a cooler,
- Low mass in comparison to steel inlets
- Fasteners made of SS304 or SS316 stainless steel
- Standard operational temperature: -40°C do +65°C
- Possible AS/SG-4 execution (ATEX zones)
- Standard colour: RAL 7035 or RAL 5015. Any RAL colour available on demand
- Designed for operation with ErP 2015 compliant fans
