1. Material options
- Heavy-gauge hot-dip galvanized steel is used for external unit steel panels and structural elements featuring Baltiplus 800TM Corrosion Protection.
- For casing panels we use UV resistant fiberglass reinforced polyester. The Baltiplus 810TM coating is an optional extra. A hybrid polymer coating for longer service life, applied pre-assembly to all hot-dip galvanized steel components of the unit.
- Optional stainless steel panels and structural elements of type 304 or 316 for extreme applications.
- Or the economical alternative: a water-contact stainless steel cold (and hot) water basin. Its key components and the basin itself are stainless steel.
2. Heat transfer media
Our heat transfer media is patented BACross fill with integrated drift eliminators certified by CTI. Thermal cooling tower performance was shown in comprehensive lab thermal performance tests and offers you unrivalled system efficiency.- Patented BACross fill eliminates water splash-out and allows freeze free winter operation. The fill pack includes individual sheets. Sheets are easy to inspect and clean inside the tower without dismantling, eliminating the need for frequent fill replacement. Optional telescopic support for easy fill replacement.
- In self-extinguishing plastic, which will not rot, decay or decompose.
- For operation above 55°C, try our optional high temperature fill, usable with intake water up to 60°C.
3. Air movement system
S3000E fan system features two corrosion resistant sheaves, belt and motor. Together with the heavy duty fan shaft bearings and the moisture protected motor, this guarantees optimal and year-round operational efficiency.- Fan(s) in corrosion resistant aluminum, encased in fan cylinder with removable fan guard. To reduce noise even further, choose for a low noise or Whisper Quiet fan with minimal impact on thermal performance.
- Easy removable UV-resistant plastic combined inlet shields at air inlet. Sunlight block to prevent biological growth in tower, filter air and stop water splash-out.
4. Water distribution system
These consist of:
- Low pump gravity water distribution basin with wide non-clog plastic nozzles for uniform water distribution. You can easily clean and flush both nozzles and basin.
- Distribution basin covers prevent contamination of basin water due to debris etc.
- Weir dams in the hot water basin for variable flow. These close off partly the hot water basin in periods of reduced load, resulting in up to 50% power savings on process pump and ensuring freeze free operation.
- A sloped cold water basin with:
- large hinged and inward swinging access door
- anti-vortexing strainers and make up both easily accessible from inside the unit.
- optional internal walkway for easy access to the interior of the unit.
