Hy-Dry Desiccant Breather

Hy-Dry desiccant breathers control moisture by adsorption and particulate mechanically down to 1 micron from entering reservoirs during air exchange.  Rugged designs are available high vibration mobile applications.

• A wide range of breather sizes and reservoir adaptors are available to enhance any reservoir
• Desiccant beads change color signaling that is time to replace the breather

Spin-On Breathers

Hy-Pro high efficiency high capacity spin-on breathers prevent contaminant ingression into reservoirs

• Ideal for mobile applications and to replace ineffective filler-breather caps
• Fluid contamination is the root cause of most hydraulic system failures and controlling airborne contamination is critical. The synergy of Hy-Pro fluid filter elements and Hy-Pro Spin-on breathers yields clean fluid and a healthy hydraulic system

Vacuum Dehydrators (*For Purchase or For Rental)

The Hy-Pro VUD series vacuum dehydrator optimizes the balance between heat, vacuum and process design to rapidly remove free, emulsified and dissolved water and gas.  Vac-U-Dry dehydrators are also equipped with high efficiency filtration to remove particulate contamination.

• Achieve and maintain water levels down to 10 ppm for any sized reservoir
• Regain control of high ingression conditions in hours instead of weeks or months

Applications include steel mill lube systems, turbine lube reservoirs, oil flushing and reclamation, bio-diesel polishing, paper machine lube oil, gearboxes, compressors and any other hydraulic or lube applications susceptible to water contamination in oil.

Systems available for up to 100 GPM for viscosities up to ISO VG1000 with many features that set the Hy-Pro unit apart including:

• programmable thermostat and low watt density heaters
• foam sensing and knockdown circuit
