KD-C70 Series Dehydrator
KD-C70 Desiccant Dehydrator, 0.71 SCFM, 1200L/h, 0.2 to 7psi Field Adjustable Pressure

Rev : C | Rev date : 02 Oct 2024

The KD-C70 series dehydrators provide a cost-effective solution to pressurize elliptical waveguides, coaxial cables, rigid transmission lines, and antenna systems reliably. By utilizing dry pressurized air in the distribution system, condensation is prevented, ensuring optimal system performance.

The KD-C70 series dehydrators operate automatically once powered on, supplying dry air and maintaining the output pressure within the specified range. They utilize high performance, cobalt-free allochroic silica gel as the desiccant to absorb moisture and dry the air safely and efficiently. The dehydrator is equipped with a desiccant display window for users to conveniently check the dryness of the output air and the condition of the desiccant. The desiccant can be easily taken out and filed back to the dehydrator after being regenerated by a quick heating process using a microwave oven or traditional oven.
