Applications
140 bar
• Oil filtering on the oil return line to the compressor sumps of
refrigerating and air conditioning installations, running with high
working pressures, with CO2 in trancritical compression systems.
• These filters are required for the good operation of oil level regulators
and compressors. They protect them from any contaminants that
could damage them (metallic chips, filings, oxides, sludge, etc…).

CARLY advantages
• Products are compatible with CO2, as well as with its associated
oils and additives. Products are designed for use of non-hazardous
refrigerants from group 2 of PED 97/23/EC.
• Maximum working pressure: up to 140 bar with CO2 in
transcritical compression systems.
• Product classification in CE categories is performed using the
PED 97/23/EC table, corresponding to a volume-based selection.
• Automatic bypass of the internal filter when it is too dirty
and when the pressure drop generated exceeds 3 bar;
this particularity ensures the continuity of compressor
lubrication, even if filter maintenance is late.
• Hermetically sealed outer steel enclosure with paint to ensure a
high resistance to corrosion.
• Filtrating core made of stainless steel mesh cloth.
• Filtering efficient at 5 microns.
• Connections on standard products: screwed type SAE and ODF
to solder.
Possible customization on demand :
•Specific connections (O-RING, ORFS,…).
•Stainless steel casings and unions (resistance to corrosion
and at low temperatures).
•Lower filtration threshold.
•Filtering surface of the core, more or less important according
to the specificities of the machine.
• Very large filtering surface areas for very low pressure drop.

Warning
Before selecting or installing any component, please refer to the chapter 0 of CARLY technical catalogue - WARNING.

General assembly precautions
The installation of a component in a
refrigeration system by a skilled professional,
requires some precautions:
•S
ome are specific to each component,
n
and in this case, they are specified in the
RECOMMENDATIONS SPECIFIC part
defined hereafter ;
•O
ther are general to all CARLY components,
they are presented in the chapter 115 of
CARLY technical catalogue – GENERAL
ASSEMBLY PRECAUTIONS.
Recommendations specific to the oil filters HCYF-P14
•T
he oil filters are to be mounted on the
oil return line, between the oil separator
and the oil level regulator, as close as
possible to the latter.
•T
he direction of oil flow, indicated by
an arrow on the filter tag and by an “IN”
sticker next to the inlet connection, must
imperatively be respected.
•T
he degree of clogging of the filters must
be regularly checked, ensuring that the
oil return is correct in the crankcases
of compressors; oil filters must be
imperatively replaced at the first sign of
clogging.
• It is highly recommended to install
downstream oil filter an oil sight glass
HCYVP-P in order to visually check the
presence and the condition of the oil.
• HCYF-P14 oil filter only ensures
mechanical filtering of solid contaminants.
• Make sure that the piping can support
without deformation the weight of the oil
filter; otherwise, plan the attachment of
the oil filter with a clamp on a stable part
of the installation.

Special precautions for components used with CO2 in transcritical systems
•The maximal working pressure and the power variations of the installation must be taken into account as of its design, in
order to select all the components consequently.
•The pressure of the circuit during the stop phases must also be taken into account, because it can be very high, due to the
pressure equalization according to the ambient temperature; several solutions exist to limit and control this pressure when
the installation is stopped.
- Design of the installation allowing to resist to this pressure.
- Implementation of a « buffer » volume of storage or expansion (receiver).
- Installation of a secondary circuit with valve or solenoid valve, allowing the fluid transfer to the coldest point, or the
less high in pressure of the installation.
- Implementation of a small separate refrigeration unit, to maintain the liquid temperature at a pressure lower than the
maximal working pressure ; it is so far the most effective technical solution, but with a major drawback, which is the
power failure (safety unit to be considered, or backup power supply).
• The implementation on the liquid line of a filter drier DCY-P14, or a filter drier shell BCY-P14 equipped with drying cores
CCY 48 HP or PLATINIUM 48, is highly recommended. Serious problems can occur in the presence of moisture, such as
expansion valve blocking and formation of dry ice and even carbonic acid. To avoid this, it is imperative to limit the circuit
openings in order to avoid air introduction, causing the condensation in the pipes, and to proceed to a high evacuation of the
installation, before any commissioning or restarting.
• For an operation with CO2 at low temperature, provide thermal insulation on the components which can be covered by frost.
•There is no incompatibility between CO2 and the main metallic materials commonly used in refrigeration systems (steel,
copper, brass...)
•O
n the other hand, there is a real compatibility issue between CO2 and polymers. For example, swelling phenomena and
internal explosion of the seal are possible. Carly oil filters HCYF-P14 do not have polymer gaskets directly in contact with
CO2.
