1. Material options

  • Heavy-gauge hot-dip galvanized steel is used for unit steel panels and structural elements featuring a zinc aluminium coating. Outside casing featuring Baltiplus corrosion protection.

2. Heat transfer mediaTrilliumSeries finned coil

  • The V-shaped finned coil is constructed of staggered or parallel tubes in:
    - seamless copper (15,9 diameter tubes, 0,4 mm thickness)
    with aluminium, rippled and corrugated fins (0,17 mm thick and 2,12 mm fin spacing).
    - or stainless steel 304L (12,7 diameter tubes, 0,7 mm thickness) with aluminium, rippled and corrugated fins (0,14 mm thick and 2,54 mm fin spacing).
  • Thick and seamless copper or stainless steel headers and threaded steel connections
  • Designed for maximum 21 bar operating pressure according to PED. Pneumatically tested for 30 bar.
  • Try our option for aggressive environments: special pre-coated anti-corrosion aluminium fin.

3. Air movement systemTrilliumSeries fans

  • Axial fan with exceptionally compact direct drive short integrated motor and fan guard.
  • The low profile fan with fan guard features an impeller and motor and is balanced as a complete unit using dynamic single plane balancing. Balance grade is G6.3. 
  • Fan and motor totally maintenance free, allowing frequent starting and -40° to 60°C air temperature.
  • Bearings seals and motor encapsulation for long service life.

4. Adiabatic pre-coolerTrilliumSeries pre-coolers

  • Evaporative cooling pad of impregnated cellulose with different flute angles encased in bolted heavy gauge stainless steel.
  • Distribution pad on top for complete pad wetting.
  • Once-through water distribution system, no need for pumps, water drained to sewage.

5. Electrical panel and adiabatic controls (option)TrilliumSeries electrical panel

  • Factory-installed electrical panel and step controller or variable frequency drive with integrated adiabatic controls.
