AlfaBlue BXM/BXD Air-cooled gas coolers General information & application 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. The AlfaBlue series is a wide range of heavy-duty gas coolers for air conditioning and refrigeration applications. AlfaBlue gas coolers are available for both horizontal and ver­ical air direc­ t tion, either in single (M) or dual (D) coil execution. Alfa Laval offers a wide range of CO2 gas coolers with capacities ranging from 15 up to 750 kW. Alfa Laval CO2 gas coolers AlfaBlue AlfaBlue Junior Alfa-V Alfa-V Single Row * ir temperature = 35°C, CO2 at 90 bar, gas temperature in/out = 120/38°C a Coil An innovative coil design based on small diameter copper tubes and corrugated aluminium turbo fins provides excellent heat transfer at minimal refrigerant charge. Standard fin s ­ pacing is 2.1 mm. Circuiting design is fully optimized to the thermodynamic properties of CO2. Stainless steel header tubes for on-site welding connections. Available in different fin thicknesses and fin spacings. ­ Separate connections in the D series provide the opportunity for independent operation of both gas cooler coils. Casing Frame construction provides high rigidity for protection against vibration and thermal expansion. Casing and framework of corrosion resistant pre-galvanized sheet steel (corrosion ­esistance class C4), epoxy coated white RAL 9002 on r both sides. Separated fan sections. Fan motors Available in four fan diameters (630, 800, 910 & 1000 mm) and five noise levels, power supply 400/50/3. Motors with external rotor, protection class IP 54 according to DIN 40050. Integrated thermo contacts provide reliable protection against thermal overload. EC fan motors available.
