The existence of particulates circulating
in the refrigerant-side of an operating
chiller or refrigeration system can lead to a
multitude of problems. The impact of this
condition may ultimately include reduced
performance, chiller degradation and/or
complete shutdown and failure. One
particularly harmful source of particulates
having a significant impact on a system
involves the circulation of residual
contaminants invariably left remaining
following the performance of a hermetic motor
burnout cleanup using traditional methods.
One of the most serious and costly events
confronted by contractors and chiller owners
is the dreaded hermetic motor burnout. This
catastrophic occurrence spews contaminants
including acids, motor windings and other
particulates throughout the chiller system.
The damage to the physical system is often
costly and creates a time-consuming ordeal to
clean up. And if the system is not thoroughly
decontaminated, the risk of a premature burnout
of the replacement motor is substantial.
Hermetic motor burnouts commonly occur from
the effects of moisture (see
Wet
Refrigerant) and heat which break down
refrigerants causing the formation of acids.
These contaminants ultimately impact the motor
windings and the presence of excess moisture
may cause a short circuit within the motor.
Other culprits resulting in premature motor
burnouts include product defects and/or low
voltage.
From a preventive perspective, periodic
testing and monitoring of refrigerants is the
recommended means to avoid or reduce the
likelihood of premature hermetic motor burnout
caused by contaminated refrigerants. (see
Refrigerant/Oil
Sampling). Once a burnout
occurs, however, Hudson's patented technology
assures rapid and complete system and
refrigerant decontamination. The results and
benefits of using Hudson's solution for
hermetic motor burnout cleanup are
unparalleled and quite measurable.
First, the removal of all contaminants from
centrifugals, screw or reciprocating chillers is
assured the first time. The chance of a second
premature burnout caused by residual
contaminants and particulates that traditional
methods typically leave behind is obviated.
Perhaps, one of the most compelling
observations is the sheer quantity of
particulates and contaminants removed by
Hudson technicians after cleanups using
traditional methods have been completed.

In summary, this process assures: |
 |
Removal of all contaminants from
centrifugal, screw or reciprocating chillers
the first time |
|
|
Minimizes or eliminates callbacks |
|
|
Minimizes the likelihood of a second
premature burnout |
|
|
Systems are totally purified in hours |
|
|
Minimizes need for cleanup kits, extra
filter cores and suction driers |
