Energy Savings average $ 24,000 a year per chiller

The Purger is designed to continually clean oil, acid and moisture from a chiller's refrigerant charge and return the oil to the chiller's compressor lubrication circuit, oil reservoir sump, where it belongs. The purger's operation of oil separation and refrigerant cleaning is accomplished via a unique process utilizing the properties of gravity, heat and pressure exclusively to function. The Purger does not utilize mechanical pumps of any type .

The Purger's oil separation and refrigerant cleaning is accomplished by repeatedly extracting from the chiller evaporator (cooler) batches of oil-contaminated refrigerant, approximately 10 to 20 pounds, per each cycle. The oil-contaminated refrigerant is then heated via a distillation heater, which causes the liquid refrigerant to vaporize (boil-off) thereby distilling out contaminating oil. When the temperature of the accumulated distilled oil reaches 145 degrees F it is essentially pure oil, wherein it is automatically returned to the chiller's oil reservoir (sump).

The Purger operates around the clock non-stop as long as power is applied, whether or not the chiller is operating, and cleans between 850 to 1250pounds of contaminated refrigerant weekly.

How the Purger Works

The Purger continually draws off a small quantity of refrigerant, typically 10 to 20 pounds at a time. The refrigerant is then distilled back to the chiller leaving the oil behind. The recovered oil is then automatically returned to the chiller's oil sum p where it belongs. Acids and moisture are also removed from the refrigerant and oil during the process.

Because the purger operates 24 hours a day around the clock, regardless of chiller operating status, the refrigerant is permanently maintained in a virtual oil free state. This is true even in those situations where significant oil crossover occurs due to excessive oil seal wear.

The Purger is a totally passive device that operates independently of the chiller and has no effect on chiller operation other than cleaning the refrigerant, saving energy and increasing capacity. Operation of the Purger is accomplished, without an inductor pump , via a unique process utilizing gravity, heat and pressure exclusively to function.
