Desiccant Filter – Drier Cores
Refractron Technologies Corp. is a leading OEM manufacturer of technical ceramics &
desiccant cores. Products include both controlled porosity and densely structured ceramics
designed to meet requirements specified by our customers for durability, chemical, corrosion
and wear resistance, toughness, and density.
Desiccant Filters Drier Cores are custom designed to remove damaging contaminants from
refrigeration and air-conditioning systems. Refractron is an OEM producer of custom,
proprietary, filter drier cores for these applications and is a proven OEM manufacturer reliably
producing quality parts to meet a variety of custom requirements.
The purpose of the filter core is twofold: a) to remove moisture, acid along with other
contaminants from refrigerant breakdown and b) to take out dirt and particles. The cores
remove moisture from the refrigerant by adsorbing and retaining the moisture deep within the
desiccant grain structure. The blend of desiccants may include molecular sieves, activated
alumina, activated carbons and others that are specially formulated to meet the requirements
of each specific application. The core also is an efficient particulate filter removing scale,
solder, dirt and any other debris that may be in the system to protect the compressor, capillary
tubes, valves and other close tolerance components. Refractron has a patented Durasieve TM
material that has excellent moisture capacity in a molded core configuration.
Refractron’s porous desiccant filter-driers cores are commonly referred to as core blocks,
molded cores, filter cores, filter elements and desiccant blocks. The available sizes and
shapes are limited only by the tooling and can be in the form of a disc, puck, block or tube. These components are designed and fabricated with controlled pore size, uniform porosity
throughout for optimum filtration and adsorbency.
Other Refractron products include a range of porous ceramic filters, diffusers, dispersion parts,
vacuum chucks, and gas probes. In addition zirconia structural ceramic tubes, sleeves and
other components for corrosion and wear resistance in valves and pumps.
Refractron works closely with our customers to define their needs and requirements of each specific OEM desiccant core application. Our engineering and sales team is great at attacking technical design and process problems, then customizing an innovative solution using our broad range of advanced industrial ceramics and desiccants.
