1.2 Description
MR050BSeriesdehydratorsprovidedryairfor
pressurizing small (up to 280 liters, or 10 cubic
feet,involume)antennaandtransmissionline
systems.Thedehydratorsproduce-40ºC(-40ºF)
dewpointdryairatanominalrateof1.4liters
(0.05cubicfeet)perminuteuptoatotalof8495
Iiters(300cubicfeet)onasingledesiccant
canister.
Eachdehydratorconsistsofanelectrically-
driven air compressor, a desiccant canister, an
automatic transmission line pressure sensing
system,andalarmoutputshousedinarigid
metalchassis.Itisdesignedtomountdirectlyto
therack,directlyonawall,orasafree-standing
unit.Thefrontpanelfeaturesacontrolinterface
withdisplayforalarmsandpressure.Foreasy
serviceability, power connections, alarm output
connections,andthedesiccantcanisterare
easilyaccessiblefromthefrontoftheunit.
TheMR050Bmaintainstransmissionline
pressures between 2.0 and 3.4 kPa (0.3 and
0.5psig).Itisintendedforusewithhigh
performancemicrowaveantennasandearth
station antennas.
1.3 Operation
MR050Bseriesdehydratorsincludea
compressor,colorindicatingdesiccant,highand
low-pressure sensors, and a low-pressure alarm
sensor.
Whensystempressurefallstoapresetlow
limit,thelow-pressuresensoractivatesthe
compressor.Airischanneledthrougha
desiccantcanister,wheremoistureisadsorbed.
Theairexitsthedryingcanisterat-40°C(-40°F)
dewpoint.Itisthenchanneleddirectlytoan
internal4-portmanifold
.
Whensystempressurereachesapresethigh
limit,thehigh-pressuresensorshutsoffthe
compressor.Acheckvalvepreventssystemdry
airfromretreatingbackthroughthecompressor.
Ifsystempressurefallssignicantlybelowthe
