  • Gas-heated infrared emitters are subject to wear during operation, so that it is necessary to use them after a useful life of between approximately two and four years replace. Furthermore, they usually have to be serviced once or twice a year to check whether the gas nozzles in the mixing tube or the heater itself its function is impaired by pollution.
  • the exchange and the Maintenance of the well-known spotlights is very time-consuming, since several assembly steps to loosen the lamp housing and to clean the nozzles when the drying unit has cooled down and is therefore not in operation. This causes downtimes of the system in which the drying unit is integrated, for example a coating system for paper or cardboard webs.
