“Sustainability is part of our core values”

Man­ag­ing Direc­tor Hol­ger Michal­ka explains how “Made by Rein­hausen” has been shap­ing sus­tain­able devel­op­ment togeth­er with cus­tomers for gen­er­a­tions.


What does sustainability mean to Reinhausen?

Sus­tain­abil­i­ty has shaped our actions for gen­er­a­tions. As a fam­i­ly-owned com­pa­ny, Rein­hausen thinks and acts with a long-term per­spec­tive and a com­mit­ment to future gen­er­a­tions. This is reflect­ed in our open and val­ues-based cor­po­rate cul­ture as well as in the dura­bil­i­ty and qual­i­ty of our prod­ucts.

What is Reinhausen doing to promote sustainability?

We are dri­ving the sus­tain­able trans­for­ma­tion of our com­pa­ny world­wide and are cur­rent­ly fur­ther devel­op­ing our decar­boniza­tion roadmap as a cen­tral guid­ing frame­work. The focus is on reduc­ing our car­bon foot­print across the entire val­ue chain — from pro­cure­ment and pro­duc­tion to the use of our prod­ucts. At the same time, we take a holis­tic view of sus­tain­abil­i­ty and, in addi­tion to envi­ron­men­tal aspects, also strength­en social respon­si­bil­i­ty and clear gov­er­nance struc­tures — from human rights to bind­ing stan­dards in our col­lab­o­ra­tion with sup­pli­ers.

Reinhausen sees itself as an enabler of the energy transition. What does that mean?

We help our cus­tomers oper­ate their grids in a sta­ble, effi­cient, and future-proof man­ner. Our tap chang­ers and con­trol solu­tions make it pos­si­ble to reli­ably inte­grate renew­able ener­gies as well as the elec­tri­fi­ca­tion of heat­ing and mobil­i­ty into pow­er grids and to com­pen­sate for volt­age fluc­tu­a­tions. In addi­tion, we sup­port cus­tomers with dig­i­tal solu­tions such as mon­i­tor­ing and con­di­tion-based main­te­nance to increase oper­a­tional reli­a­bil­i­ty and use resources effi­cient­ly. We sup­port oper­a­tors through­out the entire life­cy­cle of their sys­tems so they can meet the require­ments of the ener­gy tran­si­tion.

Customers also have sustainability goals. How can Reinhausen help them achieve these?

We are work­ing to reduce the car­bon foot­print across the entire life­cy­cle when devel­op­ing new prod­ucts. To help our cus­tomers bet­ter assess the envi­ron­men­tal impact of their sys­tems, we pro­vide Envi­ron­men­tal Prod­uct Dec­la­ra­tions (EPDs).

In addi­tion, we are pub­lish­ing our first group-wide sus­tain­abil­i­ty report this year. This allows us to make our progress mea­sur­able, and clear­ly demon­strate where we have already made progress and where fur­ther action is need­ed. In this way, we ensure max­i­mum trans­paren­cy regard­ing our ongo­ing mea­sures — not only for our cus­tomers, but for all oth­er stake­hold­ers as well.


An exam­ple of how our onload tap-chang­ers for grid appli­ca­tions are becom­ing more sus­tain­able with every prod­uct gen­er­a­tion.

In 1978, Rein­hausen launched the OILTAP® V, a tap chang­er that was very com­pact for its time. A nov­el­ty at the time: Both the oil hous­ing and the dri­ve shaft were made of glass-fiber-rein­forced com­pos­ites, which, thanks to their high dura­bil­i­ty and long ser­vice life, con­tribute to reli­able oper­a­tion for decades.

Around the turn of the mil­len­ni­um, Rein­hausen intro­duced vac­u­um tech­nol­o­gy to tap chang­ers. Thanks to this tech­nol­o­gy, the oil is no longer con­t­a­m­i­nat­ed, and for the first time, it is pos­si­ble to oper­ate the tap chang­er with vir­tu­al­ly no main­te­nance. This reduces the need for ser­vice calls and low­ers the car­bon foot­print by elim­i­nat­ing the need for oil treat­ment. In addi­tion, vac­u­um tech­nol­o­gy enables the use of more envi­ron­men­tal­ly friend­ly, alter­na­tive insu­lat­ing flu­ids.

With the VACUTAP® VI, Rein­hausen engi­neers have tak­en the on-load tap-chang­er to a whole new lev­el of sus­tain­abil­i­ty. This tap chang­er shares the oil sup­ply with the trans­former and is con­trolled via a direct dri­ve. This elim­i­nates the need for addi­tion­al com­po­nents and saves mate­r­i­al, reduces oil and space require­ments, and allows trans­form­ers to deliv­er more pow­er while main­tain­ing the same size. Thanks to its clever design, instal­la­tion is also sim­ple and resource effi­cient.
