The discharge pressure is 0.5 psig with a maximum flow rate of 6.0 standard cubic feet per hour (2.8 l/min) with a typical dew point below -40°C. Neither light level nor height present a viewing problem, since the EDH-4 indicates pressure and status by using a bright red LED display.
A microcontroller regulates pressure and controls all dehydrator functions. Solid state control of all functions ensures reliability. A convenient container, accessed through a removable front panel door, contains the replaceable desiccant. Modular sub systems eliminate the need for special tools and test equipment, should repairs ever be required. The EDH-4 limits continuous compressor operation to four hours in the event of a severe leak.
The EDH-4 120/230 VAC, 50/60Hz supply voltage source selection and switchable English or SI calibrations, ideally suit the EDH-4 for a wide range of global applications. The maximum power requirement is 40VA. Available rack, wall and outdoor NEMA 3R mounting options combined with a -40°F (-40°C) to 140°F (60°C) operating temperature range provide location flexibility.
120/230 volt 50/60 Hz operation
Selectable English or SI calibration
Rack, wall, or outdoor mounting
