Forty year old actuators still going strong

27 January 2015

Actuators from AUMA’s first type range, SA 4 – 70, have been operating reliably at a district heating and power generation plant owned by ERZ Entsorgung + Recycling Zurich customer for four decades. Currently around 500 AUMA actuators are deployed at three combined heat and power plants and a 160 km district heating network operated by ERZ.

With the introduction of a Siemens T3000 process control system, the original actuators – which are dispersed across different plant sections – are gradually being replaced with the company’s latest generation of IntelligentSA .2 actuators. Combined with PROFIBUS DP these devices can be directly integrated into the Siemens DCS.
