A sealing system for infrared emitters developed by Heraeus Noblelight GmbH, Hanau, Germany, has been granted IP65 certification by VDE Offenbach. The system allows the use of infrared systems for outdoor heating processes, where it will protect against the ingress of dirt or spray water. This system was tested by the VDE in Offenbach, Germany, in June and July and proved itself sealed to dust and spray, conforming with VDE 0710 DIN40050, relating to IP65.

Heraeus Noblelight's infrared emitters are used in many process heating applications, where they provide high heat transfer capacity, heat transfer without contact and high efficiency.
