High pressure sight glass (PS = 52 bar) Types SGP N, SGP I and SGP X

Transcription

1 MAKING MOERN IVING POSSIBE ata sheet igh pressure sight glass (PS = 2 bar) Types SGP N, SGP I and SGP X Sight glasses are used to indicate:. The condition of the refrigerant in the liquid line of the plant. 2. The flow in the oil return line from the oil separator.. The moisture content in the refrigerant. The SGP X are mainly used to indicate the condition of the refrigerant as well as the liquid level in the receiver or the oil level in the compressor. The SGP N and SGP I are equipped with sensitive indicators that reflects a colour, depending on the moisture content in the refrigerant. Features Type SGP X (without indicator) y Indicates lack of subcooling y Indicates refrigerant deficiency y Indicates liquid level in receiver y Indicates oil level in compressor y Flare-/solder connection or socket type Type SGP I (with I type indicator) y For CFC and C refrigerants y Indicates too high moisture content in the refrigeration system y Indicates lack of subcooling y Indicates refrigerant deficiency y Flare-/solder connection or socket type Type SGP N (with N type indicator) y For CFC, FC, C and R44 refrigerants y Indicates too high moisture content in the refrigeration system y Indicates lack of subcooling y Indicates refrigerant deficiency y Flare-/solder connection or socket type KRCC.P.EK anfoss A/S (RC-MP/sw),

Be aware that polyester oil for refrigerants like, e.g. R4a, R404A, R40C react with water in a hydrolysis generating acid and alcohol. The recommended levels of moisture content are usually between 0 and ppm, where hermetic compressors only tolerate very low moisture content, while semi-hermetic and other compressors normally tolerate higher moisture contents in the refrigerant. The on the sight glass indicator depends on the moisture content of the refrigerant. The values under green/ are to be considered as perfect condition meaning full protection against harmful effects from moisture. In other words, the filter drier is working perfectly. If the green starts to fade, the change has begun and the indicator should therefore be watched more carefully. If the changes to yellow it is a clear signal, that the capacity of the filter drier is exceeded and should be replaced as soon as possible.
