MMS90Intelligent moisture management
for transformer oil — 24/7.
An on-line single-cylinder dehydration system that quietly removes water from transformer insulation before it can rob your asset of life — backed by a PLC, dual sensors and 10 years of onboard data.
Engineered to be seen.
Built for uptime. Designed for engineers.
Six engineered stages — from always-on operation to fail-safe isolation — work as one continuous moisture-management pipeline.
On-line continuous operation
24/7 dehydration without taking the transformer offline.
