Constructed with 3/8" diameter copper tubes, CHN range, and 1/2" diameter copper tubes, CAH range, manufactured according to CUPROCLIMA specifications and with corrugated aluminum fins. They allow for high efficiency.
All batteries are leak tested at a test pressure of 3,923 kPa (40 kg/cm2) and then pressurized with nitrogen to 147 kPa (1.5 kg/cm2) to prevent corrosion of the inner surface of the copper tubes.
The cooling unit's enclosure structure is made of galvanized steel; its external surface is painted with epoxy-polyester and then baked at 180°C, providing high corrosion protection, even in extreme environmental conditions. Metal protection is provided on connections and return bends.
The fans have diameters of 630 mm (CHN range) and 910 mm (CAH range), and are equipped with three-phase external rotor motors (400 V @ 50 Hz). High-efficiency EC fans are available.
For vertical air inlet (VV), or horizontal air inlet (HI).
