Retrofit & Modernization Services


Even the best technology eventually starts to show its age, keep your machines ready for the future with the ALL NEW G120X.

Drive systems need to run safely and reliably, as a result, the drive train and all its components are subject to extreme wear and tear, and these factors also increase the risk of unscheduled downtime over the years. This risk can be averted with specific retrofit measures.

We offer a full range of options as part of our retrofit program – for Siemens and third-party products alike – that increase the availability, reliability, and energy efficiency of the drives installed at your plant.

In our retrofit solutions for integrated drive systems (IDS), we take a holistic approach that focuses on the drive train in its entirety: motors, converters, and gear units. Our comprehensive retrofit program includes a large variety of options – one of which is bound to match your requirements.

If you are concerned about aging equipment and need to maintain reliability Alpha Drives Ltd are offering a service where we will work with you to replace old VSD’s such as SED2’s, Micromasters any other brand you may have.

Engineers from Alpha Drives Ltd will help you to migrate to the latest equipment and make the project a success, from the initial inventory to planning the best actions to take, implementing the project, and finally commissioning your system.

SINAMICS G120X: Master the elements

SINAMICS G120X is the new frequency converter from the proven SINAMICS family of drives – optimised for infrastructure and industrial water/wastewater applications as well as pumps and fans in building automation. This makes SINAMICS G120X the first choice for users who want to tap into the power of the elements. Part of a complete and seamless family of products, the frequency converter meets practically every requirement.

Unlock your drive’s digital potential and harness the power of the elements.

Specific functions for water / waste water applications

  • Deragging function to sustainably remove deposits and dirt from pump impellers.
  • The pipe filling mode allows pipes to be gently filled at the beginning of the control process before going into closed-loop controlled operation.
  • The innovative cavitation detection function protects pumps and reduces maintenance costs.
  • The keep running mode reduces the speed before a possible shutdown.
  • Multipump operation (staging) allows several pumps to be controlled from just one frequency converter.
  • Many additional functions, directly supported by the converter, makes SINAMICS G120X universally applicable in infrastructure projects.

Specific functions for HVAC applications

  • The flying restart function reduces starting times after brief power failures.
  • SINAMICS G120X also provides an automatic restart function after power failures.
  • The essential service mode maintains fan operation for smoke extraction systems or emergency ventilation systems for as long as required in extreme situations.
  • Multipump operation (staging) allows for the control of several pumps with just one frequency converter.
  • Skipping critical motor speeds is another HVAC-specific feature which reduces vibration and, in turn, premature wear.
  • SINAMICS G120X also provides a real-time clock for autonomous, time-controlled operation as well as a timestamp for fault and alarm reports


With SINAMICS G120X, the new low cost frequency converter comes as a complete product series – standardized and seamless when it comes to all supply voltages and supply types and is available in a power range extending from 0.75 kW to 630 kW.
