EWCO 240 Hypochlorous Acid Generator System

The EWCO 240 system is a compact, low-maintenance, single stream system that generates hypochlorous acid (HOCl) in solution through the electrolysis of salt and water. The system uses patented electrolysis cells that are unique in that they generate a stable HOCl molecule that is electrically neutral and with high oxidation potential (>800 mV), contributing to its effectiveness against microbial pathogens.

Why should you choose onsite generation?

Athena Cleanse = $70/gallon

Hypo 7.5 = $0.20/gallon

One gallon of bottled hypochlorous acid (such as Athena Cleanse or Clear Line) will cost anywhere from $70 to $150 USD. With the Hypo 7.5 machine, you can make 2 gallons of 500 ppm* hypochlorous for $0.40 USD--and that includes the amortized cost of the machine, which comes with a 5-year or 2,000 hour warranty.

With onsite generation, you have complete control over the quantity and strength of your hypochlorous. Make as much as you want, whenever you need it, at an extremely low cost. 

*For reference, Current Culture's Clear Line is 1500 ppm and Athena Cleanse is 280 ppm.

Hypochlorous acid is a non-toxic multipurpose solution for all aspects of a hydroponic system. It is the most effective form of chlorine and has a neutral pH, low TDS, and is organic-approved by the USDA. Hypochlorous is the active ingredient in popular brands such as Athena Cleanse, Current Culture's Clear Line and UC Roots, and Plant Aid.

What can hypochlorous acid do?

• Root zone optimizer
• Pre-germination seed soak
• Equipment sanitation
• Biofilm eliminator
• Descaler
• Antifungal + sporicidal
• Produce rinse
• Cuttings dip
• Growing media cleanser
• Algae inhibitor

Dosage

Hypochlorous acid can be added directly to water systems, (R) deep water culture tanks, flood tables, hydro-buckets, and misters. Free available chlorine levels should not exceed 5 ppm at the plant root.

• Descaling: 5 ppm in a recirculating system or 500 ppm for flush to waste
• Root zone optimization: 2-4 ppm in a recirculating system
• Equipment sanitation: 200 ppm dip or soak
• Growing media: 200 ppm soak (>10 minutes), then rinse with water
• Cuttings: 10 ppm dip
• Seed sanitizer: 2 ppm soak 
• Produce wash: 50-100 ppm (dependent on type of produce)
