Strainer housing Type FIA 250-300

(10-12 in.) Brings reliability and durability demanded in industrial refrigeration applications

FIA 250-300 (10-12 in.) strainers are a range of angleway strainers, which are carefully designed to give favourable ow conditions. The design makes the strainer easy to install, and ensures quick strainer inspection and cleaning.

FIA strainers are used ahead of automatic controls, pumps, compressors etc., for initial plant start-up and where permanent ltration of the refrigerant is required. The strainer reduces the risk of undesirable system breakdowns and reduces wear and tear on plant components.

FIA 250-300 (10-12 in.) strainers are equipped with a screen mesh of stainless steel, available

in sizes 150 and 250 (microns 72 mesh ()).

Mesh is the number of threads per inch. μ (microns) is the distance between two threads (1μ = 1 /1000 mm)

Refrigerants

FIA strainers are currently authorized by Danfoss for use with more than 70 R-numbers HCFC, non-ammable HFC, Ammonia, CO2 and hydrocarbons.

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 specic refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Housing

The strainer housing is made of special, cold resistant steel.

Strainer Insert

A lter grid and lter net of stainless steel ensure long element life. The lter net oers a very high degree of cleanability

Selection of strainer size

The mesh aperture size of the strainer must satisfy the requirements stated by the suppliers of the equipment to be protected. The following recommendations of aperture size apply in general to refrigeration installations:

Table 8: Selection of strainer size

NOTE:

Mesh is the number of threads per inch. μ (microns) is the distance between two threads (1μ = 1 /1000 mm).

Kv values

Table 10: Kv values

Installation

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.
