Specifications
The document details options for soldering copper pipes and the availability of filters with copper tube and ORFS threaded connections. Filters in series 42 and 43 are composed of molecular sieves and activated alumina, offering high acid adsorption and dehydration capabilities.
Design and Functionality
Filters are designed for maximum fluid flow efficiency, preventing clogging by trapping impurities. They are chemically inert and ensure minimal charge loss.
Filter Selection
Guidelines for selecting filters based on refrigerant flow and water capacity are provided, with example calculations for specific conditions.
Tables
Tables include specifications for refrigerant flow capacity, water capacity, and dehydratable charge at various temperatures, assisting in filter model selection.
Procedures
Installation and operation of bi-flow filter driers are described, emphasizing proper flow direction and efficient dehydration.
Standards
Filter driers comply with ARI STANDARD 710-2004 and DIN 8949:2000, with specified conditions for liquid temperatures and equilibrium point dryness.
Recommendations
To optimize performance, it is recommended to limit moisture before installing the drier and use by-flow filter driers in heat pump systems to reduce external piping.
Tables and Data
Tables provide details on filter characteristics, dimensions, weights, refrigerant flow capacities, and water capacities.
Construction and Materials
Filters are made with steel bodies and solder connections, featuring a solid core of molecular sieves for high water and acid adsorption.
Block Replacement Procedure
  • Close the valve on the departing line.
  • Transfer refrigerant charge to the high-pressure side.
  • Stop the compressor at a safe pressure.
  • Replace the filter block quickly to prevent air entry.
  • If air enters, create a vacuum in the low-pressure side.
  • Open the liquid line valve and restart the compressor.
  • Top up the charge if necessary.
Filter Characteristics
  • Classified as "Pressure vessels" under Directive 94/23/EC.
  • Designed for systems using Group II refrigerants.
  • Constructed with steel bodies and solder connections, featuring a large surface to stop particles up to 20 microns.

DEHYDRATION OF REFRIGERANTS Among contaminating agents causing serious damages to refrigerating systems, moisture plays a major role. Its presence, even possible in the refrigerating system, is due to many factors: - inadequate or insuciently prolonged vacuum before refrigerant charging - oil used for topping up remained exposed to air humidity - refrigerant used for subsequent additions contained in non dried vessels - sealing defects especially in systems not designed for operation at low temperatures High temperatures combined with humidity give rise to complex phenomena enhancing acid formation...

e shape of the block is designed in order to oer the maximum possible surface area to the incoming uid. e internal cavity is also positioned in such a way as to have a uniform wall thickness. As a result, the uid encounters a constant strength at all points, ows linearly through the block, and ensures ecient dehydration and minimum charge loss. e block is chemically inert, not deliquescent, does not react with refrigerating uids, and is capable of blocking oil by-products dragged into the circuit. Impurities accumulate in the ring between the metal shell and the block; this prevents lter clogging....
