Primozone Cooling Skid
The Primozone Cooling Skid Module (CSM) is a high‑efficiency cooling solution engineered specifically for water‑cooled Primozone GM-ozone generator. To maintain maximum ozone production and ensure uninterrupted operation, stable cooling water is essential. The CSM enables facilities to use locally available process water—freshwater or seawater—while protecting the ozone generator through a closed-loop design.
The system separates the process water loop from the ozone generator cooling loop, preventing contamination and safeguarding the generator from dirty or corrosive water. This makes the Primozone CSM the preferred cooling solution wherever on-site cooling water is available.
The Primozone CSM is equipped with a heat exchanger, either in stainless steel (SS) for fresh water or titanium for sea water (TI), and an expansion tank. The CSM makes a closed loop, with the ozone generator(s) on one side and the cooling water on the other, to prevent any dirty water contamination. Therefore, mitigating the risk of damage to the ozone generator.
The Primozone CSM is available in a single pump or a dual pump configuration. The dual pump configuration safeguards your equipment by alternating the pumps for a safer installation.
Note: the cooling water temperature will affect the produced amount of ozone. Optimum cooling water temperature is 10°C (50°F).

Most energy‑efficient cooling solution for Primozone GM ozone generators
Cost‑effective installation and operation
Reliable performance in both freshwater and seawater applications
Extended equipment lifespan due to contamination prevention
Flexible sizing and pump redundancy options
The CSM cools Primozone GM ozone generators using on-site process water while protecting the generator through a closed-loop system.
Ozone production generates heat. Without proper cooling, ozone output decreases and equipment may be damaged.
Yes. Titanium heat exchangers (TI) are used for seawater applications to prevent corrosion.
10°C (50°F) provides the highest ozone production efficiency.
Single pump: Standard operation
Dual pump: Pumps alternate for redundancy, improving system reliability
Yes. The closed-loop design ensures process water never enters the ozone generator cooling circuit.
Yes. Primozone offers custom high-capacity cooling skid solutions on request.
The CSM is available in three standard sizes, suitable for different GM ozone generator capacities.
Energy-efficient cooling — Designed to minimize power consumption while maintaining optimal generator temperature.
Closed-loop protection — Prevents contamination and extends equipment lifespan.
Freshwater (SS) or seawater (TI) compatibility — Stainless steel heat exchangers for freshwater; titanium for seawater environments.
Single or dual pump configurations — Dual pump setups alternate operation for redundancy and increased reliability.
Three available sizes — Suitable for small, medium, and large ozone generator installations.
Custom large-capacity skids — Available on request for high-demand applications.
How the Primozone CSM Works
The CSM uses an integrated heat exchanger, circulation pump(s), and expansion tank to create a stable cooling loop.
Process water temperature requirement: +3°C to +20°C (37–68°F)
Optimal cooling temperature: 10°C (50°F) — ensures maximum ozone output
Closed-loop design: Protects the ozone generator from fouling, corrosion, and particulate contamination.
This configuration ensures consistent cooling performance even in challenging industrial environments.
Ozone generators used for drinking water purification, disinfection, and oxidation need stable cooling to maintain consistent ozone output. A CSM ensures the generator stays protected even when plant water quality fluctuates.
Ozone is used for:
Odour control
Sludge reduction
Micropollutant removal
Colour removal
Wastewater environments often have dirty or corrosive process water, making the CSM’s closed-loop protection essential.
Ozone improves water quality, reduces pathogens, and increases fish health. The CSM allows the use of seawater or freshwater while preventing contamination of the ozone generator.
Industries using ozone for oxidation, disinfection, or contaminant removal rely on stable cooling:
Chemical manufacturing
Petrochemical plants
Pulp & paper mills
Textile dyeing facilities
These sites often have variable water quality, making the CSM’s heat exchanger and closed loop vital.
Ozone is used for:
CIP (clean-in-place)
Surface sanitation
Bottling line sterilisation
Ingredient water treatment
A CSM ensures the ozone generator runs at peak efficiency even during high-demand production cycles.
These industries require ultra-reliable ozone systems for:
High-purity water
Disinfection
Biofilm control
The CSM ensures temperature stability and contamination-free cooling.
Ozone is used for air treatment, mould control, and extending shelf life. Cooling skids help maintain ozone generator performance in low-temperature environments.
Any facility running multiple GM ozone generators or high-output systems benefits from:
Dual pump redundancy
Larger custom cooling skid capacity
Stable, efficient cooling loops
