SEALED FILTER DRIERS

Bi-Flow Filter Driers

The function of a Bi-Flow Filter Drier is to capture and retain system

contaminants and moisture in order to protect system components

and prevent harmful acids formation in refrigerant systems

requiring bi-directional flow.

Applications

Henry Technologies’ Bi-Flow Filter Driers offer a high level of protection for

refrigeration and air-conditioning systems. They are specifically designed to

capture and retain moisture and solid particles from circulating throughout

the system, which can create acid that causes damage to the compressor

and other components piped within the circuit. Bi-flow filter driers are

suitable for HCFC, HFC and CO refrigerants including R-410A, and their

associated oils.

Main Features

Solid copper ODS connections

Increased drying capacity over 80% Molecular Sieve and 20% Activated

Alumina and cores

Solid particle filtration down to 150 microns

Powder coat finish suitable for UV rays and harsh environments

1000 hour salt spray tested to ASTM B117

Solid core construction of 100% Molecular Sieve desiccant

Materials of Construction

The shell is constructed from carbon steel and powder coated for corrosion

resistance. The connection is ODS and made from solid copper. The valve

plate assembly and perforated plate are made from galvanized steel. The

core is made from 100% molecular sieve. The filter pad is made from non-

woven polyester. The filter mesh is made from stainless steel.

Installation - Notes

1. A moisture indicator should be installed in conjunction with each filter

drier in order to monitor drying effectiveness.

2. Full instructions are given in the Product Instruction Sheet, included

with each filter drier.

Technical Specifications

Maximum working pressure = 650 PSI (45 Bar)

Allowable operating temperature = -40°F to +212°F (-40°C to +100°C)

Bi-Flow Filter Driers are UL and C-UL Listed by Underwriters Laboratories,

Inc. Additionally, Bi-Flow Filter Driers are CE marked in accordance with

PED.

Selection Guidelines

Sealed Filter Driers should be selected for a particular application based on a

number of factors. Full dimensional specifications are provided to ensure

easy installation. Models should be selected based both on drying capacity

and liquid capacity to ensure adequate drying and minimal pressure drop.
