Cuno STM150 Reverse Osmosis System

The STM150 and TSR150 Reverse Osmosis water filtration systems are uniquely designed to produce
consistent quality water for the specific reduction of scale causing minerals in boiler based steamer
applications. The STM150/TSR150 RO membrane is designed to reject over 96% of minerals that cause scale
build-up and equipment problems. Activated carbon and graded density pretreatment protect the RO
membrane. The post-treatment filters adjust the product water to allow electronic probes to function correctly
in water conditions up to 2,000 ppm TDS.
