AHS is applied at onshore facilities, as well on sea- and river-going vessels.

The System ensures:

  • automatic heating of antennae installed on open deck to protect them against low temperature using antenna heating units (hereinafter - AHU)
  • main/standby power switching using CSAHS and additional КРs
  • temperature set up and control inside each AHU (dome) using a repeater via digital interface RS-422
  • connection of more than one AHU to one CSAHS applying КР

Maximum number of connected AHUs to one CSAHS – 20 pcs.
