DESCRIPTION AND OPERATION OF THE PRODUCT
1.1
Description
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.
