Reduce your energy costs for dehumidification and effluent treatment by up to 80%.

STEM designs and manufactures industrial solutions based on water vapor permeable membranes — patented technology from Mines Paris PSL, commercially available.

Two industrial challenges. One common technology.

Industry faces two critical challenges: controlling humidity in its processes and reducing water consumption. STEM provides a unique solution thanks to a common technological core: membrane separation of water vapor, coupled with the exploitation of low-temperature waste heat.
NEODRY

​High-efficiency industrial dehumidification

Your dehumidification systems are consuming more and more energy due to climate change. NEODRY replaces or supplements them with unparalleled energy efficiency.
