1. Material options

  • Heavy-gauge hot-dip galvanized steel is used for external unit steel panels and structural VTL construction elements featuring Baltiplus 800TM Corrosion Protection. 
  • 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 water basin. Its key components and the basin itself are stainless steel.

2. Heat transfer media

  • BACount fillOur heat transfer media is patented BACount fill. In comprehensive lab thermal performance tests it showed proved thermal cooling tower performance and offers you unrivalled system efficiency.
  • We divide the fill pack into compact fill bundles easier to remove and replace. Each includes individual fill sheets which are easy to dismantle for thorough inspection and cleaning, hence eliminating the need for frequent 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 65°C.

3. Air movement systemFan drive system

  • With motor-driven centrifugal fan and a V-belt drive.  You can easily remove the entire mo t o r base for proper belt tensioning to ensure constantly correct belt alignment. Together with the heavy duty fan shaft bearings this guarantees optimal operational efficiency. Single- and multi-speed motors available.
  • Centrifugal fan(s) are forward-curved and nearly noiseless.  Overcome external static pressure! Use sound attenuators and duct work etc. for air intake/discharge with no loss of thermal performance!
  • Our drift eliminators come in UV-resistant plastic, which will not rot, decay or decompose and their performance is tested and certified by Eurovent.  They are assembled in easily handled and removable sections, for optimal internal access.
  • Steel eliminators, protected with the Baltiplus 810TM coating, for optimal corrosion protection, are also available for specific applications.

4. Water distribution system

These consist of:Float ball

  • A header and spray branches with wide non-clog plastic nozzles, secured by rubber grommets. You can easily remove, clean and flush both nozzles and spray branches.
  • A cold water basin with:
    - strainers which are easy to lift out and the anti-vortexing device also helps stop trapped air
    - mechanical make up
    - circular access door
