Features & Applications:
A great deal of information lies hidden behind the vibrating
needle of a typical pressure gauge. Is the TEV valve
modulating properly, or is there liquid flooding back in the
system?
Digi-Cool offers unprecedented diagnostic power with the
Digital Refrigeration System Analyzer (DRSA). The
patented pressure bar graphs allow you to see pressure
dynamics intuitively for quick diagnosis. Automatic
saturation, subcooling and superheat readings mean no
more wallet cards. Conceived by a technician with
modern engineering, the unit will endure years of field use.
The new DRSA-1100 features an integrated temperature
probe to automatically calculate superheat and
subcooling, and pressure extremes monitoring for simple
pressure controls set-up, for even greater convenience
during start-ups.
