FIGURE 5 - Sealed tube test results.
Figure 5 displays the reaction of molecular sieve
and activated alumina with a POE lubricant and HFC
refrigerant. After exposure of the desiccants to the POE
and HFC refrigerant in a sealed glass tube for 14 days
and 180°F, the activated alumina showed organic acid
levels almost 40 times higher than that of molecular
sieve. This is an indication of the breakdown of the
lubricant. The fluoride levels were low indicating com-
patibility with the refrigerant.
Parker liquid line dryers have been designed specifically
to meet the demands of the new HFC refrigerants.
R-410A in particular, due to its higher pressures, required
stronger construction to meet these working pressures.
Parker liquid line dryers are UL listed for use with
R-410A. This, in addition to increased filtration capaci-
ties, water capacity and compatibility insure that Parker
liquid line dryers will provide R-410A systems maxi-
mum protection which leads to long reliable operation.
