R-Side® Solution - Hermetic Motor Burnout

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 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. 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
