After considering all factors involved in the decision making process when choosing an electrical heat tracing solution, it is time to describe how the system works. In our case, we want to share with you the structure of our DCS AKOTRACE® solution, a framework that holds three levels of performance areas designed to fulfill the needs of any CSP plant.

The structure of an optimal heat tracing solution
After considering all factors involved in the decision making process when choosing an electrical heat tracing solution, it is time to
describe how the system works. In our case, we want to share with you the structure of our DCS AKOTRACE® solution, a
framework that holds three levels of performance areas designed to fulfill the needs of any CSP plant.
Field and installation
From the base up, Level 3 is made up of all the heat cables and heaters, probes, accessories, lagging, and, in general, of any
element necessary for the installation of the tracing system.
Control and Power
Level 2 distributes the necessary power to the tracing system, regulating and controlling its delivery according to the information
received (thermal probes and electrical supply; safety indicators, etc)

Supervision and Connectivity
Finally, Level 1 monitors and supervises the tracing system connecting it to both the plant’s DCS system and to possible
telemanagement points
All three levels of our AKOTRACE® structure are supported by a layer of services that include maintenance (reactive,
proactive and preventive), engineering, project management, installation and implementation.
In our next post we´ll do a more detailed analysis of the role each one of the levels play in the structure of
our AKOTRACE® electrical heat tracing system.
The goal of any electrical heat tracing system is to maintain the temperature, avoiding the freezing of either water or heat
transfer fluids.
How AKO does it? Let us explain in detail the three-level structure of our AKOTRACE® electrical heat tracing system
Field and Installation (level 3)
It´s made up of all the elements in the system´s control and is where the electrical heat tracing circuit is placed. It
includes all the necessary field components, and depending on the process needs each control can have:
• Either standardized or custom made heating elements, depending on the tracing needs, including MI Cable, Self
Regulating Cable, heaters and all accessories required for a full installation
• Up until 4 thermal probes with different redundancy options, this guarantees data reliability.
• Current probes that constantly monitor the system´s control energy self-consumption, warning of any drop below certain
values, allowing us to identify possible failures in those cases when several tracing sections are integrated into the same
system´s control.

Control and Power (level 2)
In this level our PROTrace® cabinets are in charge of monitoring and distributing the power from the connection point to
system´s control. They can have differentmechanism of redundancy to avoid malfunction in case of failure or during
maintenance. They are fully adaptable. Based on the application, our PROTrace® cabinets can be concentrated in different
locations or distributed throughout the field. Their final placement depends on the technical and economical needs of the
project.
Our system´s control is based on our DUOControl Trace, founded on a PLC Platform,and integrated
into PROTrace® cabinets. It receives data from the thermal probes and power supply, protection conditions, configuration
variables, etc, and it acts accordingly, regulating the output power to reach and maintain the desirable temperature, thanks
to our advanced control algorithms.
Inside our PROTrace® cabinets there is the possibility to include the kind of control, via contactor or SSR; the air
conditioning or distribution elements and the automatic transfer switch.
It also accommodates safety and protection elements such as magneto-thermal circuit breaker, differential circuit breakers
protection and a contactor´s security system in each control, adding an extra safety component in case of switcher´s
failure.

Supervision and Connectivity (level 1)
Our ProTrace® cabinets are stick to each other with optical fiber connectors. Their ring configuration allows for non-stop
communication in case of malfunction in one of the links.
In this ring configuration we have our DUOWarm Trace, supervising key variables such as power distribution and the
environment conditions in the cabinet. It also functions as agateway with the plant´s DCS system and with the firewall that
allows the internet connection to manage the installation remotely. It has a redundancy system to avoid communication
breakdowns and to facilitate maintenance work.
The local operator panel, made up of a PC Panel with our control software AKONet Trace, only needs an Ethernet link to
the network control DUOControl Trace, allowing for the total control and supervision of the tracing installation.
We have just share with you the electrical heat tracing system that makes us worldwide leaders in the sector. We have
installed this architecture solution in more than 25 plants, but we are constantly looking to innovate and find new ways to
optimize our system and at the same time, the productivity of any CSP plant.
