EFFICIENT COLD


Axial “V” shaped liquid coolers

The Liquid Coolers manufactured by FRIMETAL are designed to satisfy all the requirements of today's refrigeration market.

Dry coolers with axial fan motors of diameter 800mm and coil with a "V" shape. This set-up reduces the area occupied by an average of 35% compared with other types of condensers.

They are manufactured in two versions according to the fan turning speed, VLN(normal) and VLS (silent). The fan motors have two speed, according to delta/star connection, that makes a total of four turning possibilities:

VLN series (normal)

  • Connection D : 900 rpm
  • Connection Y : 680 rpm

VLS series (silent)

  • Connection D : 450 rpm
  • Connection Y : 350 rpm

CHARACTERISTICS

  • They can be used to cool all kind of liquids, generally water or water-glycol coming from water condensing units but also for the cooling of oil used for the lubrication of cold installations compressors.
  • Casing in galvanized and coated steel with a white polyester RAL-9002 resin of high corrosion resistance
  • Floating coil system that avoids any kind of contact between the copper tubes and the supporting end plates, assuring a long life for the condenser without leaks.
  • Axial fan motor with external rotor, three phase 400V / 50Hz and two speed. With IP-54 protection and with thermal protection (Thermocontact).

SPECIFIC OPTIONS OF THIS RANGE

  • Fan motors wired to a external junction box.
  • Fan motors type EC with electronic speed control with very high energy efficiency.
  • Liquid pipe connections by means of flanges.
  • Water spray system over the finned coil to improve the efficiency (see PA range).

Dry coolers with exchanging coils in a “V” shape and axial fans of diameter 800 and 910mm, EC type electronically commutated and three-phase connection from 380 to 480V and 50/60Hz.

These fan motors have a programmable speed control through a DC inlet 0-10V or 4-20mA. This system provides maximum energy efficiency in the whole range of speeds.

The set-up of the VLE series reduces the area occupied by the unit an average of 35% compared with other types of condensers.
