AlfaBlue BCM/BCD & BNM/BND
Air-cooled condensers
General information & application
The AlfaBlue series is a wide range of heavy-duty air cooled
condensers for air conditioning and refrigeration applications.
AlfaBlue condensers are available for both horizontal and ver
tical air direction, either in single (M) or dual (D) coil execution.
Refrigerantst
all halocarbon (BC) or ammonia (BN)
Capacities H(C)FC*t
15 up to 862 kW
Capacities ammonia*t
20 up to 1200 kW
* Nominal capacities (Tair = 25°C, Tcond = 40°C, Tsubcool < 3K, Tsuperheating = 25K).
Coil
An innovative coil design provides excellent heat transfer at
minimal refrigerant charge. Depending on the application,
condensers are fitted with cross-fin copper or smooth
s
tainless steel tubing. Available with two Alu-fin types:
Turbo fins
Industrial power fins (IF)
maximized capacity
long lasting performance
Available in different fin thicknesses and fin spacings.
Separate connections in the D series provide the opportunity
for independent operation of both condenser 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
High efficiency AC or EC 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.
