enclosed wiring in seal-tight conduits and junction boxes.The Enhanced Electrical Protection
Package control panel also includes some additional installation features and layout
improvements.The purge is also upgraded to NEMA 4 construction.The entire chiller is silicone-
friendly—all silicone is encapsulated and non-volatile so it does not affect any industrial and/or
chemical processes.
