Chillers, Heaters & Purification

Replace membranes when product water decreases and/or ppm increase. Merlin Garden Pro and Evolution RO1000 membranes reduce 94%+ of total dissolved solids. Stealth RO100/200, Stealth RO150/300 and microRO-75 membranes reduces 98%+ of total dissolved solids. The Evolution RO1000 and Merlin Garden Pro systems need two (2) membranes. For all membranes, RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output.

Removes 98%+ of all contaminants in your tap water. Leading the industry in efficiency, the Stealth has a 2:1 waste to product water ratio. Optional 1:1 ratio flow restrictor saves 50% more waste water. Customized for gardening and hydroponics. The Stealth RO™ 300 produces 300 GPD of ultra pure water. Includes: 3-stage RO unit, 2 RO membranes, carbon filter, cleanable sediment filter, automatic shut-off cartridge, wall mountable metal bracket, garden hose connector, inline shut-off, 8 ft RO and drain line, 5 ft inlet line, filter wrench and instructions. Membrane Power Flush Kit now included.

Unit size: 18.5 in x 16 in x 6 in and weight: 12.5 Ib.

Green Coconut Carbon Filters are the carbon block pre-filter that will reduce chlorine, organic chemicals, mercury, lead, PBCs, sulfur and heavy metals. #741604 is 20 in x 4.5 in. #728845 is 20 in x 2.5 in. #741646 is 10 in x 2.5 in. #741656 is 20 in x 2.75 in.

The pleated sediment filters are cleaned by rinsing regularly with a hose. The filters reduces silt, rust, dirt, sand and sediment. Change filters every 6 months. #741654 is 10 in x 2.5 in. #741642 is 10 in x 4.5 in. #741606 is 20 in x 4.5 in.

Hydro-Logic® KDF/Catalytic Carbon Upgrade Filters are advanced carbon block pre-filters effective in capturing water-soluble metals, chlorine, chloramines and scale. The carbon media is more porous than coco carbon providing a wider range of filtration.

Replacement should be performed when inlet pressure and outlet pressure difference is greater than 10%. NOTE: Systems come standard with Hydro-Logic® Green Coconut Carbon Filters but Hydro-Logic® KDF/Catalytic Carbon Filters are an upgrade option.
