VANTEC Hoses With Dielectric Union Design

comes with new technique for FCU hoses. Di-electric design.
The gasket, the nut, the inner part design is different from straight design.
The dielectric connection is used in HVAC systems to prevent or mitigate the effects of galvanic corrosion that occurs when two dissimilar metals are in direct contact with each other in the presence of an electrolyte (e.g., water). This is especially important when dealing with systems that use water for heating or cooling, as many fan coil units do.

Benefits of using a dielectric connection in fan coil units:

1. Prevention of Galvanic Corrosion

  • When materials like copper and steel come into direct contact, they can corrode due to the different electrical potentials of the metals. A dielectric connection acts as an insulator, stopping the electrical flow between the two metals and thus preventing galvanic corrosion.
  • By reducing corrosion, it extends the life of the piping system, valves, and the fan coil unit itself.

2. Increased System Longevity

  • Preventing corrosion ensures the longevity of both the fan coil unit and the entire HVAC system, reducing maintenance costs and system downtime. Corrosion can lead to leaks, blockages, and reduced system efficiency over time.

3. Better Water Quality

  • Galvanic corrosion can introduce rust, metallic particles, or other debris into the water system. This can clog filters and coils or damage pumps. By using dielectric connections, you help maintain cleaner water and better overall system performance.

4. Improved System Efficiency

  • A corroded system is less efficient due to increased pressure drops and reduced heat transfer capabilities. Using dielectric connections helps maintain optimal heat transfer and fluid flow by preventing buildup and blockages caused by corrosion.

5. Reduced Maintenance Costs

  • Fan coil units equipped with dielectric connections will require less frequent repairs related to leaks, corroded fittings, and failed piping. This translates to reduced operational costs for both maintenance and part replacements.

6. Safety

  • Corrosion can weaken the structural integrity of the fan coil unit and associated piping, potentially leading to leaks or failures. A dielectric connection mitigates this risk, providing a safer system with less chance of accidents.
