DEPU Complete Digital Solution – Controller-Limiter-Power Setpoint
Ex Proof Heat Tracing Equipment - DEPU Complete Digital Solution – Controller-Limiter-Power Setpoint
DEPU is ATEX-certified and approved for use in potentially explosive areas.
DEPU Complete Digital Solution – Controller-Limiter-Power Setpoint
- Complete solution for trace heating: controller, limiter and power setpoint adjustment all in one unit
- Alteration of adjusting parameters also possible in potentially explosive areas
- Current carrying capacity 25 A
- Fault-free full wave contro
- Sensor input, intrinsically safe
- Allows easy output adaptation to heating circuit changes
DEPU serves as complete solution for pipe heating and provides temperature control, limitation and power output control in one device. DEPU is ATEX-certified and approved for use in potentially explosive areas.
Application Areas:
- Industrial furnaces and dryers
- Heat treatment plants
- Plastic processing machines (extruders, injection machines)
- Food processing equipment
- Chemical processes
- Laboratory equipment
- Power plants
- HVAC systems
- Extruder Heating
- Hot press applications.
STRUCTURE
All functional units are integrated in a standard Ex e aluminium enclosure. Connection to mains is established through 6 mm² tension clamp terminals
FUNCTION
The controller is designed as a ON/OFF controller and measures the temperature through RTD sensor inputs. The limiter works as an independent system and measures the temperature at the hot spot with its own sensor. If the temperature exceeds the limit value the limiter interrupts the heating circuit permanently from mains and a fault alarm signal is given
The power output controller works in interference free full wave control mode by means of a semi-conductor relay. Two 7-segment displays guarantee good readability of the controller and limiter temperature values through the lid's w
