KD70 Series Dehydrator
KD70 Automatic Dehydrator, 0.78 SCFM, 1300L/h, 0.2 to 7psi Field Adjustable Pressure
Rev : G | Rev date : 02 Dec 2024
The automatic dehydrator series KD70 is specifically engineered 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 KD70 dehydrators feature high-activited aluminum oxide to absorb moisture, along with a dual-chamber system that delivers pressurized dry air while automatically regenerating the desiccant by purging collected moisture to the atmosphere. This innovative design eliminates the need for desiccant replacement or manual reactivation, making the dehydrators perfect for unattended operation, even in remote locations. With proper installation, operation, and maintenance, these units can provide years of trouble-free service.
FEATURES / BENEFITS
- High flow rate and capacity to support large size telecom, medium size broadcasting and radar applications: 0.78SCFM or 22L/min (+/-10% at 25°C)
- Pre-programed in the factory to minimize installation time on the site.
- High pressure, low pressure, excess run and dew point alarms come as standard configuration.
- 4 gas outlet ports with supplied tubing support up to 4 transmission lines, optional gas distribution manifold is available.
- Unique leakage detection function aids in inspecting the airtighness of the system.
- Supports versatile installation including desktop, rack and wall mount.
- 110VAC, 220VAC and 48VDC power models available.
- KD70S/KD72S/KD74S models can be managed by network management system using SNMP and other popular protocols.
