Replaceable Filter Drier Cores

Replaceable Filter Drier Cores

With the advent of new HFC refrigerants, the need to remove moisture from systems has become a far higher priority. This is because synthetic oil such as Polyolester, which are used with HFC refrigerants, are highly hygroscopic. If there is moisture in the system it will be absorbed by the oil, causing it to break down, resulting in acid – which will damage the system.

The solid, moulded core used in the Dry All Universal Replacement Filter Drier series is a composite of carefully selected desiccant materials which are firmly and permanently bonded together. Uniform grains of activated aluminium oxide and molecular sieves are mixed with a low content binder, this is then poured into a mould and oven baked to create a rugged solid core which will capture moisture, eliminate acids and trap contaminants.
