H.VIR® 105, type 22

The H.VIR® 105 type 22 is the largest infrared window of the H.VIR® range. Benefiting from a larger viewing angle, it covers larger field of view for inspecting electrical components. The H.VIR® 105 type 22 optical window allows you to carry out preventive maintenance through a thermographic camera in an electrical condition of normal charge (low and high voltage).

The H.VIR® 105 type 22 IR optical window can be installed on new equipment or retrofitted to existing equipment of any age. The H.VIR® 105 type 22, like other optical windows of the H.VIR® range, allows you to prevent any risks associated with electrical equipment (e.g., switchgear, transformers, busbar and motors) without pre-inspection.
