The   Vacuum   Degassing   Oven   (VDO)   is   designed   for   rapid   removal   of entrapped air bubbles in asphalt specimens The   CRT-VDO   vacuum   degassing   oven   is   of   the   highest   quality,   made out    of    a    rugged    stainless-steel    construction.    Featuring    a    built-in vacuum   source   and   glass   viewing   panel,   the   vacuum   degassing   oven   is easy   to   use   and   maintain.   Additionally,   our   vacuum   degassing   ovens are    manufactured    to    be    both    space    saving    and    energy    efficient, helping you get the best value for your investment. Vacuum   degassing   oven   CRT-VDO   will   provide   you   with   the   superior performance   that   you   need   to   get   the   job   done   right.   The   vacuum degassing   oven   will   assist   you   in   degassing   binder   materials   that   have been   PAV-aged.   This   will   ensure   that   your   binder   samples   are   in   the best possible condition. We   are   pleased   to   provide   a   vacuum   degassing   oven   that   offers   the highest   quality   and   durability   of   any   other   on   the   market.   Not   only   can the   CRT-VDO   perform   under   the   harshest   of   environments,   but   it   also supplies   fast   and   accurate   results.   The   CRT-VDO   is   among   the   safest vacuum     degassing     ovens     available,     meeting     stringent     industry standards. The     CRT-VDO     offers     a     number     of     features     that     other     vacuum degassing   ovens   simply   don’t   have.   User-friendly   and   space-saving,   the CRT-VDO   is   the   only   vacuum   degassing   oven   available   on   the   market that     features     a     completely     self-contained     vacuum     system.     With automatic,   two-stage   timing,   the   VDO   almost   does   the   job   on   its   own. And   you   will   always   know   when   testing   is   complete   because   of   the built-in,   end-of-cycle   alarm.   Manufactured   out   of   stainless   steel,   the CRT-VDO    offers    strength    and    durability    that    will    ensure    ease    of maintenance and a long lifespan. The   Vacuum   Degassing   Oven   (VDO)   degasses   through   the   use   of   an integrated   self-contained   vacuum   oven   and   vacuum   supply   controlled by    a    digital    microprocessor    with    the    vacuum    pressure    indicated directly    in    kPa    absolute,    as    specified    in    the    Standard    Practice, providing   the   operator   with   simplicity   of   operation   and   reducing   the chance of error in performing the degassing process. The   measurement   method   differs   from   most   vacuum   ovens   in   that conventional   vacuum   ovens   measure   temperature   of   the   “vacuum”, which   by   definition   a   very   poor   conductor   of   heat.   Instead,   our   device measures     where     degassed     asphalt     temperature     has     shown     to stabilise;   namely,   at   the   aluminium   support   for   the   sample   tins   which is machined from 1⁄4” [6.4mm] thick aluminium. Samples   being   degassed   may   be   monitored   visually   through   the   glass viewing window located on the units cover. KEY FEATURES • Temperature Display: Degrees Celsius Preset Preheat: 170*C • Direct-reading   Relative:   Pressure   Guage   mounted   to   align   with external kPa Absolute Scale reads 0 to -30 Hg and 0 to -115 kPa • Digital   Controller:   Integral   Temperature   with   2-stage   timing   and relay control of vacuum system. Alerts operator to load sample. • Vacuum:    Adjustment    is    provided    through    a    10-turn    metering valve located on the removable lid • Process:   10   minute   reheat   time   followed   by   30   minutes   of   heat with vacuum
