Fully welded
water cooled Resistor
2.5kW - 70kW
WHBS are compact, stainless steel, fully welded medium
power resistors. They are mainly used on board of vessels
and off-shore wind turbines where salt air conditions and
high vibrations are constantly present. WHBS style resistors are used as brake resistor for winches, steering systems and other drive systems.
The water connections are selected based on the required
water flow however in principle any water connection
style can be chosen.
Because of there compactness they are easy to install and
require minimum maintenance. They are made from stainless steel AISI304 or AISI314 and suitable in harsh environThe electrical connections can be cable lugs, threaded mental conditions. In Wind turbine applications they can

rating and ranges from 1200 to 3500V. Insulation voltage
levels are up to 3.500VAC.

WHBS style resistors are medium power
resistors ranging from 2.5 to 70kW. Because of their compact size they are ideally suited for constant load conditions
like filter applications in wind turbines or
medium power brake applications on
board of vessels. The housing is made
from stainless steel AISI 306 or AISI316
allowing them to be used in salted air
environment.
The characteristic are:

Construction made completely in
AISI 304 or AISI316

Protection degree IP66

Continuous power range from 10
to 25 kW

Working pressure 6 bar, testing
pressure 12 bar

Maximum element voltage depends on the ohm value and type.

Construction
The WHBS series has 1 or three internal
steel tube elements. The elements can
be placed in any configuration like star or
delta connection, individual or in parallel.
Connection
The WHBS can be equipped with or without connection box, depending on the
protection degree requirement. The connection can be cable lug or threated
rods.
