The heaters will be used to warm up regulated pressure gas.
Over this heaters, it was developed the Control and Safety System (ESD). This
system will check all the variables involved in the operation of the heater,
allowing the local or remote automatic start up when safe conditions are fullfilled.
During normal operation, will also be checking flame presence, normal water
level, normal temperatura, normal gas pressure, etc. In case of any deviation
from presseted values, the system will trip the heater, and local reset will
be needed to restart the heater. Also an intelligent display, allowing the
local operator to be informed of the heater status, is part of the system
The variables, commands, alarms and trips of the heater are connected to the
Scada system, both, by dry contact and modbus serial connection.
The goal of this system is the safety in the operation, allowing safe remote
control.
The complete system was developed
for Class 1 Div 2 classified area.
