SGP X, without moisture indicator, indicates lack of subcooling, refrigerant deficiency, liquid level in receiver, or oil level in compressor. It is 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. SGP X is available with flare or solder connection.
SGP N and SGP I are equipped with sensitive indicators that reflects a colour, depending on the moisture content in the refrigerant.
SGP I is for refrigerants with mineral oil e.g. HCFC. Indicates too high moisture content in the refrigeration system, lack of subcooling, or refrigerant deficiency. SGP I is available with flare or solder connection.
SGP N is for non-flammable HFC refrigerants. Indicates too high moisture content in the refrigeration system, lack of subcooling or refrigerant deficiency. SGP N are available with flare or solder connection.
