Refrigeration & Climate Components Solutions Cleaning bi-directional flow and anti-acid filter driers (liquid line) ■ Cleaning and decontamination of refrigerant circuits in refrigerating and air conditioning installations with change over in flow direction, including heat pumps. ' Temporary uses: -»new installations during start-up period for a very efficient protection of compressors against all types of dirts. -» existing installations for an efficient cleaning of the refrigerant after compressor burnout. Functional features •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 •Product classification in CE categories is performed using the PED 97/23/EC table, corresponding to a volume-based •Refrigerant flow is possible in both directions, and filtering is ensured whichever the direction. •Filtering at outlet preventing propagation within the circuit of particles bigger than 12 microns. •Two Shraeder valves for checking pressure drop, which facilitates the monitoring of filter saturation (except for model » No desorption, even at high temperatures. •Easy installation, in the liquid line between the condensing unit and terminal units (evaporators or air conditionning indoor units). > Bi-flow cleaning filter driers with very low pressure drop, thanks to an innovative CARLY patented system, in terms of flow circuiting. > Great efficiency for acid, wax binding and oily sludge neutralization at all temperatures, thanks to a fair distribution of chemical agents present in the filters: molecular sieves, activated alumina, active charcoal. 'Chemical agents in the form of free grain, for increased performance and elimination of the risk of polluting the circuit with solid particles, consecutive to drying core break-up. > No risk of discharge of the pollutants trapped inside the filter driers, during change over in flow directions. 'Very economical cleaning process with no loss of time, because the installation is still running during the ■ Environmental protection and savings of refrigerant, because using these cleaning filters allows re-use of the refrigerant after pollution control. > GOST certified products.

2 g * Refrigeration & Climate Components Solutions Cleaning bi-directional flow and anti-acid filter driers (liquid line) * Cleaning filter driers are to be mounted on the liquid line, upstream from the expansion valve. * Be careful to properly select the solenoid valves located downstream of the filter driers; their oversizing could cause liquid hammer phenomena hindering the filter driers mechanical behaviour; protection of the regulation elements upstream of the evaporator should be performed with FILTRY dirt filters (refer to chapter 8); these liquid hammer phenomena can come from other...
