- 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).
