Castel: 90 bar CO2 Replaceable Core Filter Driers

In this configuration the filter is installed in the low pressure line, being a component approved at 60 bar.
If it is necessary to increase the pressure in the low pressure side, or for some systems that do not have the low pressure side but the expansion takes place at 90 bar, it is essential to have an approved 90 bar filter, because installing a filter on the high pressure line (130bar) would require a very expensive component.
