The company says its Auto-Purger® M for halocarbons is a totally automatic, electronically controlled, noncondensible gas refrigerant purger. According to the manufacturer, this purger reduces condensing pressure, thereby saving electrical energy used by the refrigeration system. Up to four purge points can be controlled by this purger in a system up to 200 tons. The company says it is suitable for use with R-22, R-134a, R-404A, R-507, and other company-approved halocarbon refrigerants.
