Intercom solutions for chemicals

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.
