HD Series
The workhorse for mid-to-large field-erected installations — the fan that bridges the gap between package equipment and flagship D Series duties.
Engineered to your duty point.
Drop-in retrofit.
Refineries, gas plants, pulp & paper lines and steel mills are full of mid-sized cooling cells that run continuously and quietly fade into the background — until they fail. The HD Series is engineered to never become that story: four blade profiles, fully adjustable pitch, corrosion-protected hub and FRP airfoils, and a conical bushing that lets crews assemble or rebalance fans in hours, not days.
- Four blade profiles · noise vs. efficiency tuning
- Adjustable pitch · clockwise & counterclockwise
- Conical bushing for rapid hub assembly
- Aluminum or electro-galvanized hub options
Where the HD 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 HD 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
- Aluminum alloy or electro-galvanized steel
- 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
