2 Product description
2.1 Introduction
The AlfaBlue series is a wide range of heavy-duty liquid coolers. Liquid coolers are often used for
cooling down condenser water in air conditioning and refrigeration installations. In the processing
industry, liquid coolers are suitable for closed circuit cooling of various process liquids. With a wide
range of sound pressure level alternatives, these units are particularly suited to demanding, noise
sensitive environments. Available both in single (M) or dual (D) fan row: separate connections in the
dual fan row (D) models provide the opportunity for independent operation of both dry cooler coils.
Dedicated series for compressor oil coolers (BDO).
2.2 Finned coil
An innovative coil design provides excellent heat transfer. In standard execution liquid coolers are
fitted with smooth copper tubing or stainless steel tubing and corrugated aluminium turbo fins for
maximized capacity or industrial power fins for long lasting performance. Available in different fin
thicknesses and fin spacings. Separate connections in the D series provide the opportunity for inde-
pendent operation of both coils.
Model Design pressure
AlfaBlue BD 10 bar
AlfaBlue BDO 30 bar
2.3 Construction
Frame construction provides high rigidity for protection against vibration and thermal expansion.
Casing and framework of corrosion resistant pre-galvanized sheet steel, epoxy powder coated white
RAL 9002. Separated fan sections.
2.4 Fans
High efficiency AC or EC fan motors, available in three fan diameters (800, 910 & 1000 mm) and
several 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.
2.5 Optional features
•Mounting feet for vertical airflow (500 mm, 850 mm and 1200 mm)
• Coil options:
Epoxy pre-painted aluminium fins (EP), seawater resistant aluminium alloy fins (SWR), copper
fins (CU), F-coat treatment (FC)

ground them. The yellow/green grounding wire
must be left longer than the others, to ensure
that it is the last one to be detached from the
terminals in the event of the cable being pulled
off. Grounding is designed for the electrical
equipment supplied with the unit and is not to be
intended as protection from external sources.

4 Unpacking and lifting
Always follow guidelines and instructions as given in the product manual for air cooled liquid cool-
ers AHE00050.
4.1 Packing
By default, all units are shipped in horizontal airflow position. If vertical airflow is selected, mounting
feet come loose. Units are mounted on a wooden pallet, wrapped with plastic foil. As an optional,
open crate (single fan row models) or protection for headers and coil (dual fan row models) can be
selected. AlfaBlue for vertical airflow can be ordered with mounted feet. These units are shipped in
mounting position with a pallet for on-site handling.
4.2 Shipping dimensions
Dimensions in the table refer to basic units without any option, shipped in horizontal airflow position
with the different packing options available.
