DRY COOLERS

Built with modular components in hot-dip galvanised steel, powder coated in different colours (std: RAL 9002) and corrosion resistant. The curves are protected by a safety panel fastened to the structure. The fastening elements (screws, threaded inserts, rivets, washers and nuts) are all in stainless steel.

AXIAL FANS:

Maintenance-free, external rotor axial fans. Protective grid compliant with EN ISO 13857. 
  • Standard AC three-phase or single-phase: with thermal protection, lubricated for life, statically and dynamically balanced. 
  • Brushless energy-saving EC three-phase or single-phase: combines excellent performance with extremely low consumption and noise levels. 

HEAT EXCHANGERS:

  • With OVAL SECTION tubes: 12 mm nominal diameter; staggered pitch pattern and high- efficiency fins.

  • With ROUND SECTION tubes: 7,2 mm, 3/8”,
12 mm or with 5/8” nominal diameter, staggered pitch pattern and high-efficiency fins. Standard fin pitch: 2.1 mm. 
The pressure vessel is designed for a PS = 10 bar and a TS = 110 °C in accordance with EC Pressure Equipment Directive 2014/68/EU. Testing performed with dry air. 

TUBE MATERIALS
  • Standard material: copper Cu-DHP. Suitable for environments classified as
ISO 12944 C3 (e.g.: urban and industrial atmospheres, moderate sulphur dioxide levels, production areas with high humidity). 
On request: 
  • Stainless steel. Suitable for corrosive environments or in case of fluids incompatible with copper.
AISI 304 is suitable for installations in industrial atmosphere or in coastal region. AISI 316L is recommended in naval/offshore application and polluted environments. 
FIN MATERIALS
  • Standard materials: aluminum alloys A8006 or A8079 (pre-painted).Suitable for environments classified as ISO 12944 C3. 
On request:

  • Aluminum-Magnesium alloys. They provide good resistance to corrosion in marine atmospheres. AlMg fins are available in AlMg2,5 (A5052) and AlMg3 (A5754). 
  • Stainless steels: When the concentration of aggressive agents and particles in the ambient air is significant, stainless steel fins is an alternative option to a corrosion protection painting. Stainless steel fins are available in AISI 304 or AISI 316L. 

STANDARD OPERATING CONDITIONS:

  • Ambient temperature (TE) = 25°C.
  • Inlet fluid temperature (TWE) = 40°C.
  • Outlet fluid temperature (TWU) = 35°C.
  • Coolant: water.

SAFETY TESTS:

  • MD Directive 2006/42/EC (Machinery Directive).
  • PED Directive 2014/68/EC (Pressure Equipments Directive).
  • RoHS Directive 2002/95/EC (Restriction of Hazardous
    Substances Directive).
  • EMC Directive 2014/30/EC (Electromagnetic Compatibility Directive).
  • LVD Directive 2014/35/EC (Low voltage Directive).
  • ErP Directive 2009/125/EC (Eco-Design Directive).
  • EN 1048:2000 (Air Cooled Liquid Coolers Performances).
  • EN ISO 13857:2008 (Fan Guards).
