Main characteristics AlfaBlue Commercial BXS / BXE
Standard configuration
- Finned coil
The coil design provides excellent heat transfer at minimal refrigerant charge. Fitted with aluminium turbo fins and copper tubes.
- Construction
Patented coil suspension system which prevents any contact between the tubes and the support structure, protecting the tubes during transport, installation and operation. Corrosion resistant casing material, powder coated RAL9003. Separated fan sections.
- Fan motors
High efficiency AC/EC fans and low power consumption. Available in two fan diameters 500 and 630 mm. Different power supplies (230/50/1, 400/50/3, 460/60-50/3) and different noise levels. Protection class IP54 according to DIN 40050. AC motors are fitted with integrated thermo contacts to provide reliable protection against thermal overload (terminals in the box).

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-cooled gas condensers
CO2 gas coolers replace traditional air-cooled condensers in refrigerating systems that have been designed for the use of CO2 as a single refrigerant. Such installations are getting more and more widely used. In air-cooled gas coolers the hot, compressed CO2 gas flows through the gas cooler coil and is cooled down by the ambient air that is forced through the coil. Due to the thermodynamic properties of CO2, there is no phase change in the gas cooler. In CO2 refrigerant systems the refrigerant gas is not liquefied until the next system component - the expansion valve (see illustration above). Air-cooled gas coolers operate with considerably higher pressures than air-cooled condensers.
