Learn moreFAQ
Does NTH Therm also service furnaces from other manufacturers?
Yes. Our services – maintenance, DGUV-3 inspection, modernisation, commissioning and spare parts – are available for third-party systems too, regardless of the original manufacturer.
What services does NTH Therm offer?
Maintenance contracts with DGUV-3 inspection, modernisation and retrofit, commissioning and training, remote PLC support, and spare-parts supply across the full system lifecycle.
How quickly does NTH Therm respond to a breakdown?
Maintenance contracts include a 4-hour response time. Many faults can also be diagnosed and cleared by remote PLC support without a site visit.
Is modernisation worthwhile compared with buying new?
Often yes: the furnace body and insulation usually outlast the control system by a wide margin. A retrofit with Siemens S7 control, touch HMI and current safety technology typically costs 30–60% of a new installation.
