D Series
The flagship of the smartfans™ family. The reference fan for the largest field-erected cooling towers, ACC and ACHE banks in the world.
Engineered to your duty point.
Drop-in retrofit.
From base-load thermal plants to LNG fractionation banks, the largest air-cooled installations on the planet rely on fans that turn slowly, move enormous volumes of air and never stop. The D Series is purpose-built for that role: five blade profiles, adjustable pitch, conical-bushing rapid assembly and full corrosion protection across the entire diameter range from 24′ to 40′.
- Five blade profiles for fine aerodynamic tuning
- Adjustable pitch · clockwise & counterclockwise
- Conical bushing for fastest hub assembly in class
- Standard service from −45 °C to +80 °C
Where the D Series goes to work.
When the world's largest cooling installations need to cut energy, hit airflow targets and run 24/7 — they specify the D Series.
The construction manifest.
Standard materials are always corrosion-resistant or actively protected. Where corrosion is unavoidable, every interface is engineered to keep it out.
- Hub disc
- Hot dip galvanized steel with epoxy-coated central hub boss
- Airfoil profile
- Aluminum alloy or UV-resistant, antistatic FRP
- Wet tower armour
- Maintenance-free stainless steel sheet on FRP leading edge
- Blade attachments
- Hot dip galvanized steel and aluminum alloy
- Coating (optional)
- Polyurethane on any of the above components
