HVIR®

The interior of electrical equipment is often inaccessible for regular inspection. Thanks to HVIR (IR windows), it is possible to carry out maintenance testing on live equipment using thermography. Equipped with IR cameras, thermographic technicians and operators have real protection from electrical arcs (start of fire).

The HVIR is the only optical window in the world to be equipped with a Wideband crystal (Bands I, II and III) covering the field of use of all IR cameras on the market (0,3 µm to 13 µm). The use of HVIR IR windows means you can successfully prevent industrial fire risks linked to electrical equipment without production unit interruptions and without pre-inspection operations.

Properties of our infrared windows are no longer to be proven. Approved by the largest electrical equipment manufacturers in the world, the performance of the HVIR range has been validated by numerous tests and certifications.

Wintech Groupe carries 4 types of IR windows : HVIR 75 type 20, HVIR 85 type 21, HVIR 85 type EXR, and HVIR 105 type 22.

Types of HVIR windows

H.VIR® 75 Type 20

H.VIR® 75 Type 20

The H.VIR® 75 type 20 is the small infrared window of the H.VIR® range. Installed on electrical equipment, it allows you to carry out preventive maintenance through a thermographic camera in an electrical condition of normal charge.
