Applications
•tRefrigerant filtering, drying and acid neutralization for refrigerating
and air conditioning installation liquid lines with change over in
flow direction, including heat pumps.

Functional features
•tProducts 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.
•tProduct classification in CE categories is performed using the PED
97/23/EC table, corresponding to a volume-based selection.
•tRefrigerant flow is possible in both directions, and filtering is ensured
whichever the direction.
•tExternal steel body hermetically sealed with paint to ensure a high
resistance to corrosion.
•tFiltering at outlet preventing propagation within the circuit of
particles bigger than 25 microns, with a very low pressure drop.
•tNo desorption, even at a high temperature.
•tSeveral types of connections are possible on standard products:
ètTo be screwed type SAE
ètTo be brazed for tubes in inches (S)
ètTo be brazed for tubes in millimeters (MMS)
t Possible customization on demand:
•tSpecific connections (O-RING, ORFS, …)
•tAluminium casings and unions (weight optimisation)
•tStainless steel casings and unions (resistance to corrosion and at
low temperatures)
•tt onnections to braze, 100 % copper

CARLY advantages
•tMaximal working pressure: 46 bar.
•tTwo-way filter drier with very low pressure loss thanks to a CARLY
patented internal check valve system ensuring an optimum
circuiting of the flows.
•tNo risk of discharge of the pollutants trapped inside the filter driers,
during change over in flow directions.
•tGreat 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.
•tInitial drying capacity guaranteed by a 200 °C oven drying and
airtight sealing.
•t Drying ensured for the subcritical CO2 applications at low temperatures.
•tFilter driers sizes that ensure interchangeability with most products
of the market.
•tA dispenser located at the inlet ensures optimal distribution and
permanent treatment of the whole refrigerant, inside the filter drier.
•tThe 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.
•tInstallation possible in all positions.
•tGOST certified products.
