Danfoss filters（FIA15-65/FIA80-200/148H3125） for ammonia filters product introduction

Danfoss FIA ammonia system industrial filters

Overview: the FIA series filter with horns and through two kinds of structure, elaborate structure design for the flow of the refrigerant provides the best working condition. Convenient installation and easy inspection, disassemble and clean. FIA filter is usually used to control the upstream of components, pumps and compressors and other equipment, in the normal operation of system deb ing, commissioning and system filtering effect to the refrigerant. Install filter can reduce the risk of unexpected system failure, and to reduce the wear and tear of equipment components. The FIA filter USES the stainless steel mesh, mesh specifications have 100, 150, 250 and 500 mu * (microns), (American standard corresponding to 150, 150, 100, 38 eyes *).

Features:

S suitable for all kinds of no flammable refrigerant (including ammonia) and no corrosive gas/liquid medium, suitable for co2 system. Can be used in chemical and petroleum chemical industry

S module concept: general seat equipped with SVL series, can be arbitrary replacement SVL piping components platform of various functional modules

S quickly and convenient valve repair service. Easy to change at the top of the function module without welding

S stainless steel mesh does not need gasket can be installed directly, easy to maintain

S provides two types of filter: - mesh, stainless steel flat type with large filter area - fold stainless steel mesh (DN 15-200), can extend the cleaning time interval of pressure drop and lower body

S the FIA 15 to 40 (1/2 level - 1 1/2 level in.) : during the commissioning of equipment to clean up, special (50 mu) of the filter can be used in combination with standard filter

S the FIA 50-200 (2-8 in) : can provide large capacity (50 mu) filter bag, designed for system during the trial operation of equipment

To clean up

S eye: refers to the mesh per inch in length in the number of cables. Mu (microns) is the distance between the two lines (one mu = 1/1000 mm)

S the FIA (65-200. 2 1/2 level - 8 in) can be equipped with magnetic plug-in, used to attract the iron particles and other magnetic particles are clearly marked on each filter model, specifications and performance range

S body and cover the conform to the requirements of the PED pressure equipment instructions and other international standards of steel at low temperature

S temperature range: - + 60 ℃ / 150 ℃ (76 ℉ / + 302 ℉), the maximum working pressure: 52 bar (754 psi, g) g

Technical parameters:

Connection: provide the following connections:

S butt welding DIN (EN 10220), 15-200 DN (1/2 level - 8 in.)

S butt welding ANSI 36.10 wall thickness (B grade Sch 80), DN 15 to 40 (1/2 level 1 1/2 level in.)

S butt welding ANSI Sch40 36.10 wall thickness (B level), 50-200 DN (2-8 in.)

S socket (ANSI B 16.11), DN 15 to 50 (1/2 level - 2 in.)

S FPT thread, NPT (ANSI/ASME B 1.20.1), DN 15-32 (1/2 level 1 quarter in.)

Install/maintain

Body is can withstand higher internal pressure in the design, but on the whole system must be avoided effusion phenomenon occurring in a line,

In order to reduce because of heat expansion pressure impact. Should be paid attention to when installing the filter cover downward installation, ensure that flow toward the cover. Danfoss advice when liquid pipeline valve pressure drop is greater than 0.5 bar (7.3 psi) or suction piping valve pressure drop is greater than the > 0.05 bar (0.7 psi) on the filter for replacement/cleaning. Body pressure drop allowed by the maximum recommended no more than 1 bar (15 psi). Detailed information please see the FIA installation instructions.
