Who We Are
We are an independent international technical team. Our work is servicing equipment our customers already own — we do not manufacture, distribute, or resell HELIOT units. Our engineers support facilities worldwide, from semiconductor fabs to cryogenic laboratories, from automotive production lines to research institutions.
All services are delivered in English, with the flexibility to travel for on-site work anywhere in the world. Our technical work is grounded in official manufacturer engineering documentation for the equipment we service.
