Product Description
Danfoss ELIMINATOR® DCL 1.52/2.8S Liquid Line Filter Drier (023Z8255)
Danfoss ELIMINATOR® DCL 1.52/2.8S is a hermetic industrial filter drier designed specifically for light commercial systems — glass door merchandisers and low-capacity refrigeration units. The compact housing contains a core with 80% molecular sieve and 20% activated alumina, which simultaneously absorbs moisture and neutralizes acids formed in the system. Pure copper connections (inlet ¼″, outlet 2,8 mm) provide easy brazing and a reliable liquid line connection.
Key features and benefits
- DCL core — dual protection: 80% molecular sieve + 20% activated alumina effectively removes moisture and absorbs organic acids, protecting the compressor and expansion valve from corrosion and oil degradation.
- Pure copper brazed connections: Inlet ¼″ (6 mm ODF) and outlet 2,8 mm are made of pure copper — ensuring excellent sealing and simple brazing without galvanic corrosion risk.
- Monolithic core without loose grains: ELIMINATOR® technology binds the sorbent into a homogeneous block — eliminating dust carryover into the refrigerant and minimizing flow resistance.
- Thermal stability up to 120 °C: The core maintains full adsorption performance across the refrigeration system operating temperature range.
- Compatibility with flammable refrigerants (HC): The pure copper soldered version is approved for use with R290 (propane), R600a and other hydrocarbons — meeting growing environmental requirements.
- Compact design — 1,5 in3: Minimal refrigerant charge volume (net capacity 0,034 l) helps meet the 150 g charge limit for flammable refrigerant systems.
- Easy connection: The removable outlet connection cap (pull-off cap) enables quick hookup during installation.

Supported refrigerants
The filter is recommended for use with the following refrigerants: R23, R32, R134a, R290, R404A, R407C, R407F, R410A, R444B, R448A, R449A, R450A, R452A, R600, R600a, R1234yf, R1234ze.
Note: DCL filters contain activated alumina — a polar substance. When using POE/PAG oils with polar additives (e.g. corrosion inhibitors), compatibility should be checked; in such cases consider the DML series filter. Mineral oils and AB oils as well as pure POE/PAG are fully compatible.
Application
The DCL 1.52/2.8S filter drier is designed for installation in the liquid line of a refrigeration system. Especially recommended for:
- glass door merchandisers,
- light commercial equipment: supermarket refrigerators, minibars, display cases,
- systems with flammable refrigerants (R290, R600a) requiring a charge limit of ≤ 150 g,
- installations with next-generation HFC and HFO refrigerants (R448A, R449A, R1234yf, R1234ze).

FAQ — Frequently Asked Questions
What is the difference between the DCL and DML filter?
The DCL core contains 80% molecular sieve and 20% activated alumina, providing a dual function: moisture removal and organic acid adsorption. The DML core is built from 100% molecular sieve and has higher drying capacity but no acid neutralization. DCL is recommended in systems operating at high condensing temperatures where acid formation risk is greater.
Is the 023Z8255 filter suitable for refrigerant R290 (propane)?
Yes. The pure copper soldered version is approved for use with A3 flammable refrigerants, including R290 and R600a. The compact 1,5 in3 size is also designed for systems with a 150 g charge limit.
How should the filter be installed — what is the flow direction?
The filter should be installed in the liquid line according to the arrow on the housing, which indicates the refrigerant flow direction. Any mounting angle is allowed (horizontal, vertical, angled) provided the arrow matches the flow direction.
What connection does the outlet of the 023Z8255 filter have?
The outlet diameter is 2,8 mm (soldered, pure copper), and the inlet is ¼″ (6 mm ODF). This non-standard combination is optimized for minimal refrigerant charge loss in small installations with flammable refrigerants.
What is the maximum working pressure?
The maximum working pressure (PS/MWP) is 46 bar / 667 psig (based on fatigue testing). The refrigerant temperature range is -40 °C to +70 °C.
