When feedstock chemicals flow across large sites, extreme environments and noise all around, security and communication plays an integral role to enhance safety and smooth workflows. Instant two-way voice communication with unique speech intelligibility as well as site-wide announcements via integrated PA-systems minimize risks in these often explosive environments. Ex-proof terminals are especially developed for these types of zones where chemicals are at risk of igniting.
