Expert Opinions and Consultancy on Technical Insulation in Industrial Plants

Industrial Plant - REICHINGER INGENIEURE - EiiF TIPCHECK Audit - Energieeffizienz - Stephan-F. Reichinger

Industrial plants can only be operated cost-effectively and sustainably if insulation systems are installed in accordance with the generally recognised rules of technology and are constantly maintained.

Damage to the metal cladding can result in rainwater penetrating the insulation system. On the one hand, moisture reduces the insulating effect, on the other hand, moisture in insulation systems can lead to damage to the insulation system as well as to corrosion of the insulated object. In addition to increasing energy losses, damage due to corrosion can also lead to spontaneous, dangerous system failure and thus to unwanted system shutdowns and costly maintenance measures.

EiiF TIPCHECK Energy Audit and FROSIO Insulation Inspection - Stephan Reichinger

Uninsulated objects in industrial facilities represent massive energy losses. The European Industrial Insulation Foundation (EiiF) introduced so-called TIPCHECKs more than 10 years ago. TIPCHECK stands for Technical Insulation Performance Check. Specially trained TIPCHECK engineers are able to quickly discover and quantify potential savings in industrial plants. This programme is a standardised audit in accordance with ISO 50002 and EN 16427.

Payback times can be in the range of a few months, depending on the operating conditions. In particular, previously uninsulated components of permanently running systems represent massive energy losses. Retrofitting insulation not only saves thermal energy but can also significantly reduce CO2 emissions. Especially in view of extremely increased energy and CO2 emission certificate costs, insulation work can pay off very quickly.

The EiiF Tesla example shows impressively that the annual energy losses of an uninsulated DN 150 fitting operated at 150 °C all year round could power a Tesla for 20,000 km. Find out more here:
