Data Sheet
Strainer housing
Type FIA SS
Designed for highly demanding production environments, where corrosion is a risk due to harsh environments
FIA SS strainers are a range of angle-way and straight-way strainers which are carefully designed to give favourable flow conditions.
The design makes the strainer easy to install, and ensures quick strainer inspection and cleaning.
FIA SS strainers are used ahead of automatic controls, pumps, compressors etc., for initial plant start-up and where permanent filtration of the refrigerant is required. The strainer reduces the risk of undesirable system breakdowns and reduces wear and tear on plant components.
In certain specific areas such as outdoor applications and corrosive atmospheres, such as coastal installations, there is a need for high surface protection to prevent failure due to corrosion.
Today's food safety standards often call for daily treatment with detergents to protect against bacteria growth, again producing a need for high surface protection.

New refrigerants
Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.
When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specific refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Installation/Maintenance |
||
The strainer is designed to resist high internal pressures. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion.
Install the strainer with the cover in downward position.
Danfoss recommends replacement/cleaning of the strainer when the di‡erential pressure loss >0.5 bar (7.3 psi) in the liquid line and >0.05 bar (0.7 psi) in the suction line. The max. permissible di‡erential pressure is 1 bar (15 psi).
For further information refer to installation guide for FIA SS.
