Anyone who operates thermal oil plants and does not regularly service them, takes the full risks!” says Karsten Bednarz, customer service manager at heat 11. Without maintenances and relevant evidences the plant operator does not only loose his warranty claims against the manufacturer of the plant, but under some circumstances even his insurance coverage. “This can be very expensive or even existence-threatening!” continues Bednarz.
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. Where this is not the case, expensive plant failures up to the destruction of the plant are the consequences.
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. “In the event of damage, the required evidences otherwise can not be provided”, says Bednarz.
Scheduled preventive maintenances of the plant and heat transfer medium are therefore the best protection against expensive plant standstills and repairs. “An annual maintenance normally costs only a fraction of the damage that occures in the event of a plant standstill or even a necessary repair of the plant!” knows Bednarz from his many years of experience.
However, when it happens after all that a plant stops or does not operate properly, quick and uncomplicated help must be provided. “Therefore we are available to our customers 7 days a week for 24 hours!”, emphasizes Karsten Loedige, service technician at heat 11, the credo for his work.
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.
“Our customers should take care of their production, we will do the rest!” outlines Bednarz the service philosophy of heat 11. It does not matter which company originally supplied the plant. Bednarz concludes: “We are pleased with any inquiry because our customers are always amazed at how much money they can save in the maintenance!”
