Mongstad TavleTeknikk AS

Inverters

Energy optimized, process control and safe operation

Powerful performance. Precise control. Proven security.

MTT delivers and integrates low - and medium ac drives (VFD) from Rockwell Automation. The solutions be designed, installed and the pump with a focus on reliability, energy efficiency and documented compliance with current requirements and standards.

Typical challenges for customers

Outdated or manual motor controller with high energy consumption
Big starting currents and voltage dips that affect networks and other devices
Væskeslag and trykkpulser in the processing plant with direct started engines
Lack of integration between the frequency inverter, PLC and process control
Unclear interface for the operation, service, documentation, and security level
Strict requirements for cyber security

Inverters – High Voltage

The PowerFlex® 7000 MV

The PowerFlex® 7000 MV is delivered in air-cooled or liquid cooledconstruction and is available in a wide power range, from 150 – 25000 kW. The inverter is power controlled and the perfect choice for retrofit, long connection cables, demanding loads and regenerative operation.

Ac drives – low voltage

PowerFlex® 755T

PowerFlex® 755T from Rockwell Automation is designed to reduce the harmonic distortion, the regeneration. The series will also include multi- converter solution with common DC-bus. PowerFlex 755T is the first omformerene that comes with TotalForce®technology. PF 755T include "Active Front End" as the default. MTT also offers the standard 6-pulse converters from Rockwell, complete system solutions with EMC and sinusfilter where this is necessary.
