Simple
Serviceable Secure SmartQuotes from Various Food Retail Engineering Managers
“Preferred system is plain, simple DX “The biggest desired improvement is an open
refrigeration” with some “intelligent design” that protocol system where all monitoring devices across
improves overall energy efficiency” equipment and the whole building have the ability
simple - smart - sustainable to communicate with one another.” -smart-
“I believe in keeping things simple.” “We have to move to green!”
-sustainable-
“ One of my biggest pet peeves is the various
telemetry systems we have. It would be “We see case controllers as simple because we’ve
ideal to have one system, at a high level, and trained our techs on them. We put the time and
to have that information pushed to me effort in to training.” -simple-
globally.” -smart-
“One of the things we need to see, we’re going
“ As far as what’s out there today, & as far as me
to see, is more of a plug-and-play type
protecting the company; still lean to strong DX operation
situation.” -simple-
with ease of operation ” -safe/stable/simple-
“We keep our Design Relatively simple DX refrigeration”
