PolyGap® from MANGOLDT – your advantage

Thanks to PolyGap®, MANGOLDT chokes score highly on the global market with their superior performance and maximum service life. The key to this lies in the design of the air gap – instead of a single gap, MANGOLDT chokes with this design have a large number of small air gaps.

Diagram compares magnetic fields in transformers with an air gap, two gaps, three gaps, and PolyGap® technology. PolyGap® prevents magnetic fields in the windings, reduces hot spots, and lowers losses.

PolyGap® improves magnetic induction control, reduces stray flux to an absolute minimum and prevents unwanted power loss, especially at high harmonics and frequencies. It also makes our chokes quieter than any others on the market.

This core and coil design – optionally with indirect water cooling – ensures that heat is effectively dissipated and prevents local overheating. PolyGap® thus extends the average service life of our chokes to over 20 years. Save yourself costly early replacements and annoying downtime!
