Our MI cable technology for heating solutions can withstand the harshest conditions: high radiation, vacuum or high pressure, aggressive media, high temperatures, high watt density...
When the environment does not permit standard heating solutions, we can offer our services to design a specific heating solution. Our team is used to making designs to match your specifications for:
- Construction standards (mechanical: ASME,YVL, KTA, RCC-M, RCC-MR, RCC-MX, RCC-MRx electrical: KBE, RCC-E, TBE, IEEE )
- CATIA thermal and mechanical modeling
