Designed to cool transformer oil
May 1st 2011 A modular air heat exchanger
designed to cool transformer
oil – the AlfaBlue BO from
Alfa Laval – comes in a range
of capacities from 50 to
600kW and is suitable for insitu
and remote installations.
Modular in nature, the
coolers are of the OFAF (Oil
Forced/Air Forced) type and
are supplied either skid or palletmounted
for simple installation and
start-up. Units can be installed
vertically or horizontally, depending
on the duty. Fan motors are
removable, ensuring rapid access
for cleaning/maintenance and the
casing is strong enough to
withstand vibration and thermal
shocks.
The aluminium fans come in
three diameters – 800, 900 and
1000mm) and are arranged in a
single row. Five different fan speeds
and/or noise levels can be selected. The
unit is also available in a dual-fan speed
version. The fan motors use energy
sparingly due to low static pressure. More articles from Alfa Laval Limited: |
