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 may
ultimately include reduced performance,
chiller degradation and/or complete shutdown
and failure. Chief among the identified
offenders include liberated rust particles and
residue forming deposits on tubes and systems
components and the residuals following a
Hermetic Motor Burnout.
Particles of rust frequently become dislodged
from chiller shells and other system
components (see
Rust & Residue) and are carried
throughout the system by the circulating
refrigerant and lubrication system. The
consequences may be dire when the particles
accumulate on the tube surfaces, particularly
the enhanced fin tubes, and other system
components. This situation has been regularly
observed on many chillers serviced by Hudson.
The effects of these deposits can be quite
dramatic ranging from significant reduction in
heat transfer and the plugging of system
components including orifices, distribution
plate and oil filters, to ultimate
degradation of chiller performance leading to
shutdown.
This condition generally occurs as the result
of the entry of moisture in the
refrigerant-side of a system (see
Wet Refrigerant) causing rust accumulation on
chiller shells and piping and the ultimate
release of particulates into the refrigerant. In
the case of rust particulate, Hudson has
developed a unique RefrigerantSide® Solution
to eliminate the deposits and restore the
system to optimal performance.

This solution
includes: |
 |
Identification of the appropriate chemical
cleaning agents by Hudson's chemists to
dissolve rust from tube surface and vessel |
|
|
Use of patented technology and processes to
eliminate accumulated deposit |
|
|
System dehydration, if aqueous solutions used |
|
|
Online system decontamination to remove rust
and other contaminants suspended throughout
the system. |
| |
|
|
The net effect of this process is the
elimination of the rust accumulation and the
restoration of the system to optimal
performance. Hudson's RefrigerantSide®
