Power control panels

CETAL power control panels are designed for industrial heating applications

We have developed a turn-key standard range to offer the best cost and delivery time.

Customized Power control panel can also be designed and manufactured according to customer spcification.

Reliability and robustness are key drivers for our engineers.

Advantages

  • Power control panels designed for industrial applications
  • Quick and safe installation and start-up
  • High-quality components (Eurotherm and Schneider Electric)
  • Safety power contactor separated from the temperature control loop
  • Optimized frame size for space saving
  • Faster engineering time

Technical description

CETAL, industrial heating system designer and manufacturer, offers you a range of turn-key power control panels optimized for your process.

Which control mode to choose ?

For processes with high thermal inertia (for example, heating of large tanks of water or oil), a power control panel with On/Off control mode (TOR) with contactor (ARS or ARC models) is recommended.

PID (Proportional, Integral, and Derivative) controls are better suited:

  • if the process consists in fast heating of liquid or gas (such as circulation heaters)
  • if a quick reaction time with temperature control accuracy is required
  • and/if a variable flowrate is needed with power control through thyristor (ART model).

For use in

  • Technical area
  • Non-ATEX environment

ATEX power control panel or panels for outdoor use are available on request.

The power control panels are equiped with high-quality components (Eurotherm and Schneider Electric).

Inside the power control panel

  • Main load break switch with external handle (lockable)
  • Fuse disconnect switch + fuses
  • 1 x safety power contactor
  • External safety loop on terminals (ARC and ART models)

On front side

  • On/Off illuminated green switch (ART model)
  • White lamp (voltage on)
  • Red lamp (global default)
  • Reset pushbutton (ART model)
  • Emergency stop pushbutton Technical data
  • IP54 steel box
  • Epoxy polyester surface, textured appearance 60 μm, colour Grey (RAL7035)
  • 3-phase 400 V + earth (without neutral point)
  • Safety transformer
  • Power and dimensions see page 3
  • Line safety contactor separated from temperature control loop
  • The PID controllers and electronic thermostats are equipped with a factory-set measurementinput which can be reconfigured by the user:
    • PT100 range from -200 to +200°C
    • TC J, range from 0 to +450°C
    • TC K, range from 0 to +1200°C
  • Wall stand included
  • Heating element connection through to terminal block, cable glands included
  • Possibility to install remote emergency stop and On/Off switches
  • Available information on any potential free terminal:
    • On/Off status
    • Globlal Default
    • Emergency stop

All our power control panels comply with IEC‑EN‑61639 / IEC‑EN‑60364 / IEC‑EN 60204 standards and 2014/35/UE, CE directive (low voltage).
