EDH-5 Air Dehydrator is a low profile, low cost waveguide or coax environment conditioner. It is engineered to help you get the best performance from your remote or mobile antenna transmission line, no matter how small or where it’s located.
This air dehydrator has a small footprint, an improved pressure sensor and efficient operations. It’s well suited for Ku and Ka band applications. The EDH–5’s go-anywhere, manually regenerated dehydrator pressurizes small volume waveguide and coax.
The discharge pressure is 0.5 psig (34.5 mbar) with a maximum flow rate of 4.77 scfh (2.25 lpm) and a typical dew point as low as -40°F/C. A microcontroller regulates pressure and manages all dehydrator functions. The EDH–5 indicates pressure and status on a bright 2-digit red LED display. Solid state control of all functions ensures reliability.
Selectable SI or English calibration ideally suit the EDH–5 and auto-select voltages from 100 to 240 VAC for global applications. The -40°F to 130°F (-40°C to 55°C) operating temperature range promotes terrestrial location flexibility.
The replaceable or rechargeable desiccant container is accessed conveniently from the front of the unit. This can be done without removing the dehydrator from its waveguide. Should repairs ever be necessary, its modular subsystems eliminate the need for special tools and test equipment. The dehydrator limits continuous air pump operation to four hours in the event of a severe leak.
