Refrigeration & Climate Components Solutions Bi-directional flow and anti-acid filter driers • Refrigerant filtering, drying and acid neutralization for refrigerating and air conditioning installation liquid lines with change over in flow direction, including heat pumps. Functional features • Products are compatible with CFCs, HCFCs, HFCs, CO2s, 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. To use CARLY components with fluids of the hydrocarbon group 1 – Propane R290, Butane R600, Isobutane R600a, Propylene R1270 – with HFOs and transcritical CO2 and for a RANKINE organic cycle application, contact CARLY technical department. • Product classification in CE categories is performed using the PED 97/23/EC table, corresponding to a volume-based selection. • Refrigerant flow is possible in both directions, and filtering is ensured whichever the direction. • External steel body hermetically sealed with paint to ensure a high resistance to corrosion. • Filtering at outlet preventing propagation within the circuit of particles bigger than 25 microns, with a very low pressure drop. • No desorption, even at a high temperature. • Several types of connections are possible on standard products: è To be screwed type SAE è To be brazed for tubes in inches (S) è To be brazed for tubes in millimeters (MMS) Possible customization on demand: • Specific connections (O-RING, ORFS, …) • Aluminium casings and unions (weight optimisation) • Stainless steel casings and unions (resistance to corrosion and at low temperatures) • onnections to braze, 100 % copper C CARLY advantages • Maximal working pressure: 46 bar. • Two-way filter drier with very low pressure loss thanks to a CARLY patented internal check valve system ensuring an optimum circuiting of the flows. • No risk of discharge of the pollutants trapped inside the filter driers, during change over in flow directions. • Great drying and acid neutralization capacity at all temperatures, thanks to a rigorous selection and a judicious mix of the chemical agents present in the filter driers (activated alumina in order to neutralise the acids and molecular sieves to adsorb moisture); the volume of free-grains drying agents used in a CARLY filter drier is greater than that present in an equivalent model with a solid core. • Initial drying capacity guaranteed by a 200 °C oven drying and airtight sealing. • Drying ensured for the subcritical CO2 applications at low temperatures. • Filter driers sizes that ensure interchangeability with most products of the market. • A dispenser located at the inlet ensures optimal distribution and permanent treatment of the whole refrigerant, inside the filter drier. • The copper-plated steel connections up to a diameter of 3/4’’ - 18 mm facilitate the brazing and allow using brazing alloys with a low silver percentage. • Installation possible in all positions. • GOST certified products.
