2 Product description
2.1 General information and application
The Alfa-V VDD series is a wide range of heavy duty dual fan row V-type dry coolers for HVAC,
refrigeration and various industrial applications such as water/glycol cooling.
For industrial applications, dry coolers are suitable for closed circuit cooling of various process liq-
uids in f.i. food, power, process and general industries. Alfa-V VDD dry coolers provide high capaci-
ties at reduced power consumption and a compact footprint.
• Capacity range (water, EN1048): 100 up to 1800 kW
• Design pressure: 10 bar. Each heat exchanger leak tested with dry air
2.2 Standard configuration
• Finned coil:
- Smooth copper tubing ø 12 and 16 mm (VDD and VDD6) or SS304 stainless steel tubing
16 mm (VDDY).
- Separate connections allow independent operation of both cooling coils.
• Fans:
-2 to 9 fan pairs, available in three fan diameters (ø 800 mm, ø 910 mm & ø 1000 mm) and dif-
ferent noise levels. ErP compliant motors with dynamically and statically balanced external rotor,
protection class IP54 according to DIN 40050 and integrated thermo contacts to provide reli-
able protection against thermal overload. AC power supplies 400/50/3, 400/60/3 and 460/60/3.
EC power supply 380-480/50-60/3.
• Casing, supports and frame made of corrosion resistant galvanized steel (class C4-H).
Separated fan sections and removable fan rings.
• Frame construction provides high rigidity for protection against vibration and thermal expansion.
• Stickers indicate fan direction and refrigerant in/out.
