So that heat transfer plants operate reliably and failure-free, regular maintenance services are indispensable. As per DIN 4754 and VDI 3033 the used thermal oil needs to be checked at least once a year for its further usage since the thermal oils – in a similar way to engine oils at vehicles – are subject to wear and tear. If this does not happen, expensive plant failures or even destruction of the plant is the consequence.

The safety equipment also needs to be regularly checked and maintained- at least annually, many safety fittings even daily. A corresponding evidence in writing must be kept for these works – which may be performed by expert personnel only.

Scheduled preventive maintenances of the plant and heat transfer medium as well as the usage of the proper spare parts and wearing parts are therefore the best protection against expensive plant standstills and repairs.

However, when it happens after all that a plant stops or does not operate properly, quick and uncomplicated help must be provided. Our service technicians are on duty around the clock! And for the important verification all relevant plant characteristics along with repair and maintenance history remain saved in the electronic data bank. So no important detail escapes, no maintenance and service appointment is missed.
