At Prometek, we took the decision to use Blueshield's new T91 LMN to protect the health of our employees.
Air quality standards are becoming more and more stringent and we want to fully comply with them. It was found, following tests that, combined with ARCAL 211 gas, the deposition rate was 30% higher and that defluxing was practically non-existent.
We have not yet measured the time savings with the T91 LMN and Arcal 211, but we are very optimistic.
