7.1 n Functional features n CARLY advantages Liquid sight glasses VCYL n Applications • Immediate and direct monitoring of flow, condition or moisture content of the refrigerant in its liquid or diphasic phase in refrigerating and air conditioning installations. C o Products are compatible with HFCs, HCFCs, CFCs, as well as with their associated oils and additives. Products are designed for use of non-hazardous refrigerants from group 2 of PED 97/23/EC. o Product classification in CE categories is performed using the PED 97/23/EC table, corresponding to a nominal diameter-based selection. o Visualisation of refrigerant through glass. o A moisture indicator sensitive to moisture and resistant to acids is positioned under the glass. o Moisture presence is characterised by a modification of the indicator colour; this modification is reversible. o The sight glasses die-cast brass body guarantees perfect resistance to corrosion. o The brazed liquid sight glasses’ long copper sleeves allow quick and safe brazing of connections; since the body and the glass are attached, brazing can be performed without removing the glass. o The large size of the glass and the absence of a central hygroscopic tip ensure excellent visibility. o The moisture indicator fastening system ensures protection against erosion and prevents fouling by oils and dirts present in the circuit; it also eliminates any turbulence that would hinder proper vision of the refrigerant and does not lead to any pressure drop. o The sealed design and the seaming principle of the chosen glass ensure perfect air-tightness. o Two very thick hexagon head bolts facilitate sight glasses positioning and handling for tightening of connections to screw. o The male/female sight glasses to screw are provided with a guided copper gasket that allows fast and reliable positioning. o GOST certified products.
