Main characteristics AlfaBlue Junior AG
Standard configuration
- Finned coil
Innovative coil design manufactured from Cu tubes and corrugated aluminium turbo fins. Standard fin spacing 2.1 mm. Each heat exchanger is leak tested with dry air and finally supplied with a nitrogen pre-charge.
- Construction
Patented coil frame design allowing thermal expansion and offering protection against vibration (f.i. during transportation). Corrosion resistant casing material, coated RAL9002. Separated fan sections.
- Fans
High efficiency AC or EC fans with innovative polymeric fan blades and low power consumption. Available in three fan diameters 350, 500 & 630 mm, different power supplies (230/50-60/1, 400/50-60/3) and four noise levels. Protection class IP 54 according to DIN 40050. AC motors are fitted with integrated thermo contacts to provide reliable protection against thermal overload (terminals in the box). Motors may be wired to one or more common terminal boxes.
- High pressure condensers
A special range of high pressure AGH condensers (design pressure 45 barg) is available with circuiting design optimized for refrigerant R410A. This AGH range has been specifically developed for AC applications and may be tailor made for OEM use.

How it works
Alfa LU-VE finned coil air heat exchangers have been designed to achieve an optimized exchange of thermal energy between air and a refrigerant or fluid. The ‘heart’ of our air heat exchangers is the finned coil, built up from a circuit of interconnected tube serpentines and fins to increase the heat exchanging surface. Thanks to the combination of key design variables (coil materials, coil geometry, casing design, fan type), air units are very versatile heat exchangers with a great variety of applications in many industries. Alfa LU-VE supplies finned coil air heat exchanger products for a wide variety of applications.
Air coolers & air-cooled condensers
Air coolers and air-cooled condensers are key components in air cooling and airconditioning systems. On the refrigerant side the most common media are a brine or an evaporating refrigerant like HFOs, HFCs, ammonia or CO2. A chilled brine may be supplied from a chiller that is potentially located far away, but a liquified refrigerant must come from a nearby condensing unit. When an evaporating refrigerant is used, the cooling coil is the evaporator in the vapour-compression refrigeration cycle (‘direct expansion’ or ‘DX’ system).
