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.

FANS:

  • Standard AC three-phase or single-phase: thermal protection, lubricated for life, statically and dynamically balanced.
  • Brushless EC / energy-saving: combines excellent performance with extremely low consumption and noise levels.
  • Centrifugal fans on which the impeller has backward curved aluminum blades, keyed directly onto the rotor of the electric motor.


COILS:

OVAL SECTION tubes: 12 mm nominal diameter, in copper or bimetallic (aluminium-copper), with a staggered pitch pattern and high-efficiency aluminium fins with 2.1 mm pitch.
Alternatively ROUND SECTION tubes: 12 mm nominal diameter in copper, or with 5/8” diameter in copper or – only specially made - stainless steel, with a staggered pitch pattern and high-efficiency aluminium fins with 2.1 mm pitch.

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).
