LIQUID MANAGEMENT

Replaceable Core Filter Driers

The function of a filter drier is to remove system contaminants, acid

and moisture.

Applications

The Henry Technologies range of replaceable core filter driers are

designed to be used in both the liquid and suction lines of refrigeration

and air-conditioning systems. The product range is suitable for use with

HCFC, HFC and CO refrigerants (see core data).

Materials of Construction

Drier Shells

The main shell and fixed end caps are constructed from carbon steel

and are powder coated for corrosion resistance. The cover plate is

constructed from nickel plated steel. The ODS connections are copper.

Cores

Each core is constructed from a molded composite of desiccant

material(s) bonded to provide very high mechanical strength, micronic

filtration, high moisture absorption and acid removal where applicable.

Each core is fully activated and placed in a hermetically sealed

container.

Technical Specifications

Maximum working pressure = 609 PSI (42 Bar)

Allowable operating temperature = -40°F to +158°F (-40°C to +70°C)

Selection Guidelines

The user should select a model based on refrigerant type, refrigeration

capacity and the preferred degree of moisture/acid removal required.

The preferred connection size can then be matched to the system

requirements to establish which model is best. Alternatively, the user

may select a connection size first and then check that the application is

within the refrigeration capacity limits of the selected model.

Note

: The user may decide to oversize the filter-drier based on

experience or if the system contamination level is likely to be higher than

normal.

Installation - Notes

1.

Install the filter drier upstream of the liquid line controls to

give the maximum protection. Locate upstream of moisture

indicator so that drying effectiveness can be measured.

2.

Ensure dimension ‘F’ is complied with in order to remove

cores.

3.

It is recommended to install the unit horizontally for easier

core replacement.
