Complete systems
Designed to work as one system.
A generator alone does not guarantee a result. We prepare the feed gas, design transfer and contact, and integrate measurement and safety.

Technical resources
Answers before you buy.
How to specify an ozone system.
An equipment list is not yet a specification. The project starts with the result that must be measured.
Read guideDry air or oxygen: choosing the right feed gas.
Feed gas quality affects output, reliability and maintenance. The choice depends on model and application.
Read guideWhy pilot wastewater before investing.
Flow rate alone cannot reliably predict ozone demand. Testing the actual water allows a response to be measured.
Read guideVenturi, mixing and contact: one connected chain.
Injecting ozone does not complete treatment. Transfer and reaction time also need to be designed.
Read guideSafety starts in system design.
Ozone is useful inside the process and can be hazardous when it escapes into occupied air. Safety belongs in the design from the start.

We know what a real installation demands.
At Grupo 7 we design, fabricate and install ozone systems. Our direct participation in many installations helps us anticipate feed gas, transfer, instrumentation, safety and operational issues before recommending equipment.
From drawing to plant
We review space, hydraulics, power, ventilation and maintenance access. A technically sound solution must also be installable and operable.
On-site verification
We compare the design with actual flows, pressure, feed gas quality, measurement points and alarm logic. Performance is verified in the complete system.
Technical responsibility
We identify missing data, needed tests and acceptance criteria. We do not promise one universal dose for every water.
Portfolio
Real installations in our partnership
Explore three installed systems using technology from our partner ZonoSistem and see how different water problems are addressed.
Irrigation water
Fasanarella irrigation, Italy
Installation of a 2 kg/h GR 2000 generator in an irrigation network designed for approximately 1,800 m³/h. The photograph shows installed equipment and hydraulic integration.
Drinking water
Drinking-water plant trial
A 3 kg/h generator installed and commissioned for dose-optimization testing at a drinking-water plant. The publication describes the trial, not a final water-quality outcome.
Recreational water
Animal pools in Madrid
A 200 g/h HIDRO VT ozone system with an injection and mixing plant, commissioned for animal-pool water treatment at a Madrid zoological park.
Our brand and representation
Grupo 7 ozone generators. Our own engineering.
Grupo 7 designs, manufactures and markets its own brand of ozone generators. We also represent AZCO Industries and ZonoSistem in the Dominican Republic and integrate their equipment when a project calls for it.
