There are also the following non-electrical components (risks
analysis already carried out):
• Fans;
Air Refrigerant gas heat exchangers, finned battery type,
with copper tubing and aluminium fins;
Cooling circuit made of copper welded with precious alloy,
completed with: lamination capillary tube, mechanical
dehydratation filter, brass valves, pressure and temperature
control devices.
The HVAC units will be equipped with a Control Box,
Power Box/es and a Box for the intrinsically safe barriers
and they will be fully controlled by a PLC (Programmable
Logic Control) and the alarms will be sent to Control Room
by free contact relay.
All the lamps and the control switches for the HVAC units
status control / monitoring will be installed in front of the
control box.
AUTOCONTROL TECHNOLOGIES, in these last years, has
developed a Graphic Controller system for the HVAC units
status control / monitoring.
This system is composed of a graphic panel for the HVAC
monitoring (alarms and status of the system) and a keyboard
suitable for the control (Temperature setting).
This system can be protected by password.
All the HVAC units can be built also for Safe Areas.
