Description

Maximum Hygroscopic Efficacy and Mechanical Protection for Synthetic Fluid Circuits

The presence of residual moisture inside a refrigeration circuit is the primary cause of hydrolysis of synthetic oils and the formation of corrosive acids, in addition to the risk of freezing, which can cause the rolling mechanism to jam. The solid-cartridge dehydrator filter with 100% molecular sieves ensures maximum water absorption capacity without trapping the refrigerant or depleting the lubricant’s additive package.

The compact, solid-core design prevents crumbling or the release of desiccant powder into the circuit, while the standard 1/4″ SAE flanged connections allow for quick, perfectly sealed installation without the need for open flames or brazing during installation or periodic replacement.

Strengths & Advantages:

  • 100% Solid Core with Molecular Sieves (3Å): Chemically calibrated selectivity to retain only water dissolved in the refrigerant, preventing oil acidification and corrosion of the compressor motor.

  • Compact, Anti-Crumpling Block: The extruded and sintered cartridge ensures superior mechanical sealing against pressure surges and vibrations, preventing the release of particulates downstream in the line.

  • Mechanical Filtration Down to 20 Microns: The built-in filter screens intercept copper slag, welding residues, and metal particles before they reach the thermostatic valve or the calibrated orifice.

  • 1/4″ SAE Flare Male Threaded Connections: Universal standard with a flange for clean, secure, and immediate mechanical tightening using standard wrenches.

  • Sturdy, Corrosion-Resistant Body (Ø 52 mm x 156 mm): Hermetically sealed welded housing with a protective epoxy powder coating, resistant to high pressures and the corrosive effects of surface condensation.
