The technical specifications of hydro-massage systems for pools can vary significantly depending on the specific model and manufacturer. However, here are some common technical characteristics that are often considered when choosing a hydro-massage system:

1. Pump Power: The pump power determines the intensity of the water jets used for hydro-massage. It is measured in liters per minute (l/min) or gallons per minute (GPM). Higher power provides a more intense massage experience.

2. Jet Adjustment: Some hydro-massage systems offer the ability to adjust the intensity and direction of the water jets, allowing users to customize their massage experience.

3. Nozzle Types: Different models may come with various nozzle types, including ball nozzles, adjustable nozzles, and different jet types.

4. Materials: It&single_quot;s essential that the components of the hydro-massage system are made from high-quality, corrosion-resistant materials, such as stainless steel or durable plastics.

5. Energy Efficiency: Hydro-massage systems can consume a significant amount of energy, so it&single_quot;s important to consider their energy efficiency to save on electricity costs.

6. Control and Automation: Some systems can be controlled using specialized remotes or automated systems, making operation more convenient.

7. Safety Features: Hydro-massage systems should have safety features, such as emergency shut-off and accident prevention systems.

8. Dimensions and Installation: When selecting a system, it&single_quot;s crucial to ensure that it fits the size and requirements of your pool. Consider the dimensions and installation methods.

9. Certifications and Standards: Verify that the hydro-massage system complies with relevant safety and quality standards and possesses appropriate certifications.

When choosing a specific hydro-massage system, paying attention to these technical specifications is crucial to ensure that it meets your needs and expectations.
