Porous Ceramics

Refractron designs and manufactures porous ceramics made from alumina (aluminum oxide), mullite and silicon carbide based formulations for a multitude of industries.  This family of porous ceramics are often chosen in place of metals, rubber and plastics for their strength, chemical durability and stability at temperatures up to 1200°C (2192°F).

Porous ceramics are used for hundreds of applications but they are often categorized into wicks, filters, spargers or fine bubble diffusers.  These products are used to aerate waste water, carbonate beverages, remove particulates from emissions, and recover precious minerals.

Refractron’s porous desiccant filter-drier cores are commonly referred to as core blocks, molded cores, filter cores, filter elements and desiccant blocks. These cores are typically a blend of molecular sieve, activated alumina, and activated carbon. Refractron features a patented Durasieve™ material that has excellent moisture capacity in a molded core configuration.

In addition to moisture removal, the cores also remove acid which comes from refrigerant breakdown.  The core is an efficient particulate filter that removes scale, solder, dirt and debris that may be in the system to protect the compressor, capillary tubes, and valves.
